### Merging
When development is complete on an issue, the first step toward merging it
back into the master branch is to file a Pull Request (PR). The contributions
back into the master branch is to file a Pull Request. The contributions
should meet code, test, and commit message standards as described below,
and the pull request should include a completed author checklist, also
as described below. Pull requests may be assigned to specific team
members when appropriate (e.g. to draw to a specific person's attention).
members when appropriate (e.g. to draw to a specific person's attention.)
Code review should take place using discussion features within the pull
request. When the reviewer is satisfied, they should add a comment to
the pull request containing the reviewer checklist (from below) and complete
the merge back to the master branch.
Additionally:
* Every pull request must link to the issue that it addresses. Eg. “Addresses #1234” or “Closes #1234”. This is the responsibility of the pull requests __author__. If no issue exists, [create one](https://github.com/nasa/openmct/issues/new/choose).
* Every __author__ must include testing instructions. These instructions should identify the areas of code affected, and some minimal test steps. If addressing a bug, reproduction steps should be included, if they were not included in the original issue. If reproduction steps were included on the original issue, and are sufficient, refer to them.
* A pull request that closes an issue should say so in the description. Including the text “Closes #1234” will cause the linked issue to be automatically closed when the pull request is merged. This is the responsibility of the pull requests __author__.
* When a pull request is merged, and the corresponding issue closed, the __reviewer__ must add the tag “unverified” to the original issue. This will indicate that although the issue is closed, it has not been tested yet.
* Every PR must have two reviewers assigned, though only one approval is necessary for merge.
* Changes to API require approval by a senior developer.
* When creating a PR, it is the author's responsibility to apply any priority label from the issue to the PR as well. This helps with prioritization.
## Standards
Contributions to Open MCT are expected to meet the following standards.
Contributions to Open MCT Web are expected to meet the following standards.
In addition, reviewers should use general discretion before accepting
changes.
### Code Standards
JavaScript sources in Open MCT must satisfy the [ESLint](https://eslint.org/) rules defined in
this repository. [Prettier](https://prettier.io/) is used in conjunction with ESLint to enforce code style
via automated formatting. These are verified by the command line build.
JavaScript sources in Open MCT Web must satisfy JSLint under its default
settings. This is verified by the command line build.
#### Code Guidelines
The following guidelines are provided for anyone contributing source code to the Open MCT project:
JavaScript sources in Open MCT Web should:
1. Write clean code. Heres a good summary - <https://github.com/ryanmcdermott/clean-code-javascript>.
1. Include JSDoc for any exposed API (e.g. public methods, classes).
1. Include non-JSDoc comments as-needed for explaining private variables,
methods, or algorithms when they are non-obvious. Otherwise code
should be self-documenting.
1. Classes and Vue components should use camel case, first letter capitalized
(e.g. SomeClassName).
1. Methods, variables, fields, events, and function names should use camelCase,
first letter lower-case (e.g. someVariableName).
1. Source files that export functions should use camelCase, first letter lower-case (eg. testTools.js)
1. Constants (variables or fields which are meant to be declared and
initialized statically, and never changed) should use only capital
letters, with underscores between words (e.g. SOME_CONSTANT). They should always be declared as `const`s
1. File names should be the name of the exported class, plus a .js extension
(e.g. SomeClassName.js).
1. Avoid anonymous functions, except when functions are short (one or two lines)
and their inclusion makes sense within the flow of the code
(e.g. as arguments to a forEach call). Anonymous functions should always be arrow functions.
1. Named functions are preferred over functions assigned to variables.
eg.
* Use four spaces for indentation. Tabs should not be used.
* Include JSDoc for any exposed API (e.g. public methods, constructors.)
* Include non-JSDoc comments as-needed for explaining private variables,
methods, or algorithms when they are non-obvious.
* Define one public class per script, expressed as a constructor function
returned from an AMD-style module.
* Follow “Java-like” naming conventions. These includes:
* Classes should use camel case, first letter capitalized
(e.g. SomeClassName.)
* Methods, variables, fields, and function names should use camel case,
first letter lower-case (e.g. someVariableName.) Constants
(variables or fields which are meant to be declared and initialized
statically, and never changed) should use only capital letters, with
underscores between words (e.g. SOME_CONSTANT.)
* File name should be the name of the exported class, plus a .js extension
(e.g. SomeClassName.js)
* Avoid anonymous functions, except when functions are short (a few lines)
and/or their inclusion makes sense within the flow of the code
(e.g. as arguments to a forEach call.)
* Avoid deep nesting (especially of functions), except where necessary
(e.g. due to closure scope.)
* End with a single new-line character.
* Expose public methods by declaring them on the class's prototype.
* Within a given function's scope, do not mix declarations and imperative
code, and present these in the following order:
* First, variable declarations and initialization.
* Second, function declarations.
* Third, imperative statements.
* Finally, the returned value.
```JavaScript
function renameObject(object, newName) {
Object.name = newName;
}
```
is preferable to
```JavaScript
const rename = (object, newName) => {
Object.name = newName;
}
```
1. Avoid deep nesting (especially of functions), except where necessary
(e.g. due to closure scope).
1. End with a single new-line character.
1. Always use ES6 `Class`es and inheritance rather than the pre-ES6 prototypal
pattern.
1. Within a given function's scope, do not mix declarations and imperative
code, and present these in the following order:
* First, variable declarations and initialization.
* Secondly, imperative statements.
* Finally, the returned value. A single return statement at the end of the function should be used, except where an early return would improve code clarity.
1. Avoid the use of "magic" values.
eg.
```JavaScript
const UNAUTHORIZED = 401;
if (responseCode === UNAUTHORIZED)
```
is preferable to
```JavaScript
if (responseCode === 401)
```
1. Use the ternary operator only for simple cases such as variable assignment. Nested ternaries should be avoided in all cases.
1. Unit Test specs should reside alongside the source code they test, not in a separate directory.
1. Organize code by feature, not by type.
eg.
```txt
- telemetryTable
- row
TableRow.js
TableRowCollection.js
TableRow.vue
- column
TableColumn.js
TableColumn.vue
plugin.js
pluginSpec.js
```
is preferable to
```txt
- telemetryTable
- components
TableRow.vue
TableColumn.vue
- collections
TableRowCollection.js
TableColumn.js
TableRow.js
plugin.js
pluginSpec.js
```
Deviations from Open MCT code style guidelines require two-party agreement,
Deviations from Open MCT Web code style guidelines require two-party agreement,
typically from the author of the change and its reviewer.
#### Code Example
```js
/*global define*/
/**
* Bundles should declare themselves as namespaces in whichever source
* file is most like the "main point of entry" to the bundle.
* @namespace some/bundle
*/
define(
['./OtherClass'],
function (OtherClass) {
"use strict";
/**
* A summary of how to use this class goes here.
*
* @constructor
* @memberof some/bundle
*/
function ExampleClass() {
}
// Methods which are not intended for external use should
// not have JSDoc (or should be marked @private)
ExampleClass.prototype.privateMethod = function () {
};
/**
* A summary of this method goes here.
* @param {number} n a parameter
* @returns {number} a return value
*/
ExampleClass.prototype.publicMethod = function (n) {
return n * 2;
}
return ExampleClass;
}
);
```
### Test Standards
Automated testing shall occur whenever changes are merged into the main
development branch and must be confirmed alongside any pull request.
Automated tests are typically unit tests which exercise individual software
components. Tests are subject to code review along with the actual
implementation, to ensure that tests are applicable and useful.
Examples of useful tests:
* Tests which replicate bugs (or their root causes) to verify their
resolution.
* Tests which reflect details from software specifications.
* Tests which exercise edge or corner cases among inputs.
* Tests which verify expected interactions with other components in the
system.
During automated testing, code coverage metrics will be reported. Line
coverage must remain at or above 80%.
### Commit Message Standards
Commit messages should:
@ -245,7 +234,7 @@ Commit messages should:

* Contain a short (usually one word) reference to the feature or subsystem

Issues are tracked at https://github.com/nasa/openmctweb/issues
Issues should include:
* A short description of the issue encountered.
* A longer-form description of the issue encountered. When possible, steps to
reproduce the issue.
* When possible, a description of the impact of the issue. What use case does
it impede?
* An assessment of the severity of the issue.
Issue severity is categorized as follows (in ascending order):
* _Trivial_: Minimal impact on the usefulness and functionality of the software; a "nice-to-have." Visual impact without functional impact,
* _Medium_: Some impairment of use, but simple workarounds exist
* _Critical_: Significant loss of functionality or impairment of use. Display of telemetry data is not affected though. Complex workarounds exist.
* _Blocker_: Major functionality is impaired or lost, threatening mission success. Display of telemetry data is impaired or blocked by the bug, which could lead to loss of situational awareness.
* _Trivial_: Minimal impact on the usefulness and functionality of the
software; a "nice-to-have."
* _(Unspecified)_: Major loss of functionality or impairment of use.
* _Critical_: Large-scale loss of functionality or impairment of use,
such that remaining utility becomes marginal.
* _Blocker_: Harmful or otherwise unacceptable behavior. Must fix.

# Open MCT Web
Open MCT (Open Mission Control Technologies) is a next-generation mission control framework for visualization of data on desktop and mobile devices. It is developed at NASA's Ames Research Center, and is being used by NASA for data analysis of spacecraft missions, as well as planning and operation of experimental rover systems. As a generalizable and open source framework, Open MCT could be used as the basis for building applications for planning, operation, and analysis of any systems producing telemetry data.
Open MCT Web is a web-based platform for mission operations user interface
software.
> [!NOTE]
> Please visit our [Official Site](https://nasa.github.io/openmct/) and [Getting Started Guide](https://nasa.github.io/openmct/getting-started/)
## Bundles
Once you've created something amazing with Open MCT, showcase your work in our GitHub Discussions [Show and Tell](https://github.com/nasa/openmct/discussions/categories/show-and-tell) section. We love seeing unique and wonderful implementations of Open MCT!
A bundle is a group of software components (including source code, declared
as AMD modules, as well as resources such as images and HTML templates)
that are intended to be added or removed as a single unit. A plug-in for
Open MCT Web will be expressed as a bundle; platform components are also
expressed as bundles.
![Screen Shot 2022-11-23 at 9 51 36 AM](https://user-images.githubusercontent.com/4215777/203617422-4d912bfc-766f-4074-8324-409d9bbe7c05.png)
A bundle is also just a directory which contains a file `bundle.json`,
which declares its contents.
## Building and Running Open MCT Locally
The file `bundles.json` (note the plural), at the top level of the
repository, is a JSON file containing an array of all bundles (expressed as
directory names) to include in a running instance of Open MCT Web. Adding or
removing paths from this list will add or remove bundles from the running
application.
Building and running Open MCT in your local dev environment is very easy. Be sure you have [Git](https://git-scm.com/downloads) and [Node.js](https://nodejs.org/) installed, then follow the directions below. Need additional information? Check out the [Getting Started](https://nasa.github.io/openmct/getting-started/) page on our website.
(These instructions assume you are installing as a non-root user; developers have [reported issues](https://github.com/nasa/openmct/issues/1151) running these steps with root privileges.)
### Bundle Contents
1. Clone the source code:
A bundle directory will contain:
```sh
git clone https://github.com/nasa/openmct.git
```
* `bundle.json`, the declaration of the bundles contents.
* A source code directory, named `src` by convention. This contains all
JavaScript sources exposed by the bundle. These are declared as
AMD modules.
* A directory for other resources, named `res` by convention. This
contains all HTML templates, CSS files, images, and so forth to be
used within a given bundle.
* A library directory, named `lib` by convention. This contains all
external libraries used and/or exposed by the bundle.
* A test directory, named `test` by convention. This contains all unit
tests declared for the bundle, as well as a `suite.json` that acts
as a listing of these dependencies. See the section on unit testing
below.
2. (Optional) Install the correct node version using [nvm](https://github.com/nvm-sh/nvm):
```sh
nvm install
```
3. Install development dependencies (Note: Check the `package.json` engine for our tested and supported node versions):
```sh
npm install
```
4. Run a local development server:
```
npm start
```
> [!IMPORTANT]
> Open MCT is now running, and can be accessed by pointing a web browser at [http://localhost:8080/](http://localhost:8080/)
Open MCT is built using [`npm`](http://npmjs.com/) and [`webpack`](https://webpack.js.org/).
## Documentation
Documentation is available on the [Open MCT website](https://nasa.github.io/openmct/documentation/).
### Examples
The clearest examples for developing Open MCT plugins are in the
[tutorials](https://github.com/nasa/openmct-tutorial) provided in
our documentation.
> [!NOTE]
> We want Open MCT to be as easy to use, install, run, and develop for as
> possible, and your feedback will help us get there!
> Feedback can be provided via [GitHub issues](https://github.com/nasa/openmct/issues/new/choose),
> [Starting a GitHub Discussion](https://github.com/nasa/openmct/discussions),
> or by emailing us at [arc-dl-openmct@mail.nasa.gov](mailto:arc-dl-openmct@mail.nasa.gov).
## Developing Applications With Open MCT
For more on developing with Open MCT, see our documentation for a guide on [Developing Applications with Open MCT](./API.md#starting-an-open-mct-application).
## Compatibility
This is a fast moving project and we do our best to test and support the widest possible range of browsers, operating systems, and NodeJS APIs. We have a published list of support available in our package.json's `browserslist` key.
The project utilizes `nvm` to maintain consistent node and npm versions across all projects. For UNIX, MacOS, Windows WSL, and other POSIX-compliant shell environments, click [here](https://github.com/nvm-sh/nvm). For Windows, check out [nvm-windows](https://github.com/coreybutler/nvm-windows).
If you encounter an issue with a particular browser, OS, or NodeJS API, please [file an issue](https://github.com/nasa/openmct/issues/new/choose).
## Plugins
Open MCT can be extended via plugins that make calls to the Open MCT API. A plugin is a group
of software components (including source code and resources such as images and HTML templates)
that is intended to be added or removed as a single unit.
As well as providing an extension mechanism, most of the core Open MCT codebase is also
written as plugins.
For information on writing plugins, please see [our API documentation](./API.md#plugins).
Following these bundle conventions is required, at present, to ensure
that Open MCT Web (and its build and tests) execute correctly.
## Tests
Our automated test coverage comes in the form of unit, e2e, visual, performance, and security tests.
The repository for Open MCT Web includes a test suite that can be run
directly from the web browser, `test.html`. This page will:
### Unit Tests
* Load `bundles.json` to determine which bundles are in the application.
* Load `test/suite.json` to determine which source files are to be tested.
This should contain an array of strings, where each is the name of an
AMD module in the bundle's source directory. For each source file:
* Code coverage instrumentation will be added, via Blanket.
* The associated test file will be loaded, via RequireJS. These will
be located in the bundle's test folder; the test runner will presume
these follow a naming convention where each module to be tested has a
corresponding test module with the suffix `Spec` in that folder.
* Jasmine will then be invoked to run all tests defined in the loaded
test modules. Code coverage reporting will be displayed at the bottom
of the test page.
Unit Tests are written for [Jasmine](https://jasmine.github.io/api/edge/global)
and run by [Karma](http://karma-runner.github.io). To run:
At present, the test runner presumes that bundle conventions are followed
as above; that is, sources are contained in `src`, and tests are contained
in `test`. Additionally, individual test files must use the `Spec` suffix
as described above.
`npm test`
An example of this is expressed in `platform/framework`, which follows
bundle conventions.
The test suite is configured to load any scripts ending with `Spec.js` found
in the `src` hierarchy. Full configuration details are found in
`karma.conf.js`. By convention, unit test scripts should be located
alongside the units that they test; for example, `src/foo/Bar.js` would be
tested by `src/foo/BarSpec.js`.
### Functional Testing
### e2e, Visual, and Performance Testing
The tests described above are all at the unit-level; an additional
test suite using [Protractor](https://angular.github.io/protractor/)
us under development, in the `protractor` folder.
Our e2e (end-to-end), Visual, and Performance tests leverage the Playwright framework and are executed using Playwright's test runner, [@playwright/test](https://playwright.dev/).
To run:
#### How to Run Tests
* Install protractor following the instructions above.
* `cd protractor`
* `npm install`
* `npm run all`
- **e2e Tests**: These tests are run on every commit. To run the tests locally, use:
## Build
```sh
npm run test:e2e:ci
```
Open MCT Web includes a Maven command line build. Although Open MCT Web
can be run as-is using the repository contents (that is, by viewing
`index.html` in a web browser), and its tests can be run in-place
similarly (that is, by viewing `test.html` in a browser), the command
line build allows machine-driven verification and packaging.
- **Visual Tests**: For running the visual test suite, use:
This build will:
```sh
npm run test:e2e:visual
```
* Check all sources (excluding those in directories named `lib`) with
JSLint for code style compliance. The build will fail if any sources
do not satisfy JSLint.
* Run unit tests. This is done by running `test.html` in a PhantomJS
browser-like environment. The build will fail if any tests fail.
* Package the application as a `war` (web archive) file. This is
convenient for deployment on Tomcat or similar. This archive will
include sources, resources, and libraries for bundles, as well
as the top-level files used to initiate running of the application
(`index.html` and `bundles.json`).
- **Performance Tests**: To initiate the performance tests, enter:
Run as `mvn clean install`.
```sh
npm run test:perf
```
### Building Documentation
All tests are located within the `e2e/tests/` directory and are identified by the `*.e2e.spec.js` filename pattern. For more information about the e2e test suite, refer to the [README](./e2e/README.md).
Open MCT Web's documentation is generated by an
[npm](https://www.npmjs.com/)-based build:
### Security Tests
* `npm install` _(only needs to run once)_
* `npm run docs`
Each commit is analyzed for known security vulnerabilities using [CodeQL](https://codeql.github.com/docs/codeql-language-guides/codeql-library-for-javascript/). The list of CWE coverage items is available in the [CodeQL docs](https://codeql.github.com/codeql-query-help/javascript-cwe/). The CodeQL workflow is specified in the [CodeQL analysis file](./.github/workflows/codeql-analysis.yml) and the custom [CodeQL config](./.github/codeql/codeql-config.yml).
Documentation will be generated in `target/docs`. Note that diagram
generation is dependent on having [Cairo](http://cairographics.org/download/)
installed; see
[node-canvas](https://github.com/Automattic/node-canvas#installation)'s
documentation for help with installation.
### Test Reporting and Code Coverage
Each test suite generates a report in CircleCI. For a complete overview of testing functionality, please see our [Circle CI Test Insights Dashboard](https://app.circleci.com/insights/github/nasa/openmct/workflows/the-nightly/overview?branch=master&reporting-window=last-30-days)
# Glossary
Our code coverage is generated during the runtime of our unit, e2e, and visual tests. The combination of those reports is published to [codecov.io](https://app.codecov.io/gh/nasa/openmct/)
For more on the specifics of our code coverage setup, [see](TESTING.md#code-coverage)
## Glossary
Certain terms are used throughout Open MCT with consistent meanings
Certain terms are used throughout Open MCT Web with consistent meanings
or conventions. Any deviations from the below are issues and should be
addressed (either by updating this glossary or changing code to reflect
correct usage.) Other developer documentation, particularly in-line
documentation, may presume an understanding of these terms.
| Term | Definition |
|---------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| _plugin_ | A removable, reusable grouping of software elements. The application is composed of plugins. |
| _composition_ | In the context of a domain object, this term refers to the set of other domain objects that compose or are contained by that object. A domain object's composition is the set of domain objects that should appear immediately beneath it in a tree hierarchy. It is described in its model as an array of ids, providing a means to asynchronously retrieve the actual domain object instances associated with these identifiers. |
| _description_ | When used as an object property, this term refers to the human-readable description of a thing, usually a single sentence or short paragraph. It is most often used in the context of extensions, domain object models, or other similar application-specific objects. |
| _domain object_ | A meaningful object to the user and a distinct thing in the work supported by Open MCT. Anything that appears in the left-hand tree is a domain object. |
| _identifier_ | A tuple consisting of a namespace and a key, which together uniquely identifies a domain object. |
| _model_ | The persistent state associated with a domain object. A domain object's model is a JavaScript object that can be converted to JSON without losing information, meaning it contains no methods. |
| _name_ | When used as an object property, this term refers to the human-readable name for a thing. It is most often used in the context of extensions, domain object models, or other similar application-specific objects. |
| _navigation_ | This term refers to the current state of the application with respect to the user's expressed interest in a specific domain object. For example, when a user clicks on a domain object in the tree, they are navigating to it, and it is thereafter considered the navigated object until the user makes another such choice. |
| _namespace_ | A name used to identify a persistence store. A running Open MCT application could potentially use multiple persistence stores. |
## Open MCT v2.0.0
Support for our legacy bundle-based API, and the libraries that it was built on (like Angular 1.x), have now been removed entirely from this repository.
For now if you have an Open MCT application that makes use of the legacy API, [a plugin](https://github.com/nasa/openmct-legacy-plugin) is provided that bootstraps the legacy bundling mechanism and API. This plugin will not be maintained over the long term however, and the legacy support plugin will not be tested for compatibility with future versions of Open MCT. It is provided for convenience only.
### How do I know if I am using legacy API?
You might still be using legacy API if your source code
- Contains files named bundle.js, or bundle.json,
- Makes calls to `openmct.$injector()`, or `openmct.$angular`,
- Makes calls to `openmct.legacyRegistry`, `openmct.legacyExtension`, or `openmct.legacyBundle`.
### What should I do if I am using legacy API?
Please refer to [the modern Open MCT API](https://nasa.github.io/openmct/documentation/). Post any questions to the [Discussions section](https://github.com/nasa/openmct/discussions) of the Open MCT GitHub repository.
## Related Repos
> [!NOTE]
> Although Open MCT functions as a standalone project, it is primarily an extensible framework intended to be used as a dependency with users' own plugins and packaging. Furthermore, Open MCT is intended to be used with an HTTP server such as Apache or Nginx. A great example of hosting Open MCT with Apache is `openmct-quickstart` and can be found in the table below.

* _bundle_: A bundle is a removable, reusable grouping of software elements.
The application is composed of bundles. Plug-ins are bundles. For more
information, refer to framework documentation (under `platform/framework`.)
* _capability_: An object which exposes dynamic behavior or non-persistent
state associated with a domain object.
* _composition_: In the context of a domain object, this refers to the set of
other domain objects that compose or are contained by that object. A domain
object's composition is the set of domain objects that should appear
immediately beneath it in a tree hierarchy. A domain object's composition is
described in its model as an array of id's; its composition capability
provides a means to retrieve the actual domain object instances associated
with these identifiers asynchronously.
* _description_: When used as an object property, this refers to the human-readable
description of a thing; usually a single sentence or short paragraph.
(Most often used in the context of extensions, domain
object models, or other similar application-specific objects.)
* _domain object_: A meaningful object to the user; a distinct thing in
the work support by Open MCT Web. Anything that appears in the left-hand
tree is a domain object.
* _extension_: An extension is a unit of functionality exposed to the
platform in a declarative fashion by a bundle. For more
information, refer to framework documentation (under `platform/framework`.)
* _id_: A string which uniquely identifies a domain object.
* _key_: When used as an object property, this refers to the machine-readable
identifier for a specific thing in a set of things. (Most often used in the
context of extensions or other similar application-specific object sets.)
* _model_: The persistent state associated with a domain object. A domain
object's model is a JavaScript object which can be converted to JSON
without losing information (that is, it contains no methods.)
* _name_: When used as an object property, this refers to the human-readable
name for a thing. (Most often used in the context of extensions, domain
object models, or other similar application-specific objects.)
* _navigation_: Refers to the current state of the application with respect
to the user's expressed interest in a specific domain object; e.g. when
a user clicks on a domain object in the tree, they are _navigating_ to
it, and it is thereafter considered the _navigated_ object (until the
user makes another such choice.)
* _space_: A name used to identify a persistence store. Interactions with
persistence with generally involve a `space` parameter in some form, to
distinguish multiple persistence stores from one another (for cases
where there are multiple valid persistence locations available.)

# Testing
Open MCT Testing is iterating and improving at a rapid pace. This document serves to capture and index existing testing documentation and house documentation which no other obvious location as our testing evolves.
## General Testing Process
Documentation located [here](./docs/src/process/testing/plan.md)
## Unit Testing
Unit testing is essential part of our test strategy and complements our e2e testing strategy.
#### Unit Test Guidelines
* Unit Test specs should reside alongside the source code they test, not in a separate directory.
* Unit test specs for plugins should be defined at the plugin level. Start with one test spec per plugin named pluginSpec.js, and as this test spec grows too big, break it up into multiple test specs that logically group related tests.
* Unit tests for API or for utility functions and classes may be defined at a per-source file level.
* Wherever possible only use and mock public API, builtin functions, and UI in your test specs. Do not directly invoke any private functions. ie. only call or mock functions and objects exposed by openmct.* (eg. openmct.telemetry, openmct.objectView, etc.), and builtin browser functions (fetch, requestAnimationFrame, setTimeout, etc.).
* Where builtin functions have been mocked, be sure to clear them between tests.
* Test at an appropriate level of isolation. Eg.
* If youre testing a view, you do not need to test the whole application UI, you can just fetch the view provider using the public API and render the view into an element that you have created.
* You do not need to test that the view switcher works, there should be separate tests for that.
* You do not need to test that telemetry providers work, you can mock openmct.telemetry.request() to feed test data to the view.
* Use your best judgement when deciding on appropriate scope.
* Automated tests for plugins should start by actually installing the plugin being tested, and then test that installing the plugin adds the desired features and behavior to Open MCT, observing the above rules.
* All variables used in a test spec, including any instances of the Open MCT API should be declared inside of an appropriate block scope (not at the root level of the source file), and should be initialized in the relevant beforeEach block. `beforeEach` is preferable to `beforeAll` to avoid leaking of state between tests.
* A `afterEach` or `afterAll` should be used to do any clean up necessary to prevent leakage of state between test specs. This can happen when functions on `window` are wrapped, or when the URL is changed. [A convenience function](https://github.com/nasa/openmct/blob/master/src/utils/testing.js#L59) is provided for resetting the URL and clearing builtin spies between tests.
#### Unit Test Examples
* [Example of an automated test spec for an object view plugin](https://github.com/nasa/openmct/blob/master/src/plugins/telemetryTable/pluginSpec.js)
* [Example of an automated test spec for API](https://github.com/nasa/openmct/blob/master/src/api/time/TimeAPISpec.js)
#### Unit Testing Execution
The unit tests can be executed in one of two ways:
`npm run test` which runs the entire suite against headless chrome
`npm run test:debug` for debugging the tests in realtime in an active chrome session.
## e2e, performance, and visual testing
Documentation located [here](./e2e/README.md)
## Code Coverage
It's up to the individual developer as to whether they want to add line coverage in the form of a unit test or e2e test.
Line Code Coverage is generated by our unit tests and e2e tests, then combined by ([Codecov.io Flags](https://docs.codecov.com/docs/flags)), and finally reported in GitHub PRs by Codecov.io's PR Bot. This workflow gives a comprehensive (if flawed) view of line coverage.
### Karma-istanbul
Line coverage is generated by our `karma-coverage-istanbul-reporter` package as defined in our `karma.conf.js` file:
```js
coverageIstanbulReporter: {
fixWebpackSourcePaths: true,
skipFilesWithNoCoverage: true,
dir: 'coverage/unit', //Sets coverage file to be consumed by codecov.io
reports: ['lcovonly']
},
```
Once the file is generated, it can be published to codecov with
```json
"cov:unit:publish": "codecov --disable=gcov -f ./coverage/unit/lcov.info -F unit",
```
### e2e
The e2e line coverage is a bit more complex than the karma implementation. This is the general sequence of events:
1. Each e2e suite will start webpack with the ```npm run start:coverage``` command with config `webpack.coverage.mjs` and the `babel-plugin-istanbul` plugin to generate code coverage during e2e test execution using our custom [baseFixture](./baseFixtures.js).
1. During testcase execution, each e2e shard will generate its piece of the larger coverage suite. **This coverage file is not merged**. The raw coverage file is stored in a `.nyc_report` directory.
1. [nyc](https://github.com/istanbuljs/nyc) converts this directory into a `lcov` file with the following command `npm run cov:e2e:report`
1. Most of the tests focus on chrome/ubuntu at a single resolution. This coverage is published to codecov with `npm run cov:e2e:ci:publish`.
1. The rest of our coverage only appears when run against persistent datastore (couchdb), non-ubuntu machines, and non-chrome browsers with the `npm run cov:e2e:full:publish` flag. Since this happens about once a day, we have leveraged codecov.io's carryforward flag to report on lines covered outside of each commit on an individual PR.
### Limitations in our code coverage reporting
Our code coverage implementation has some known limitations:
- [Variability](https://github.com/nasa/openmct/issues/5811)
- [Accuracy](https://github.com/nasa/openmct/issues/7015)
- [Vue instrumentation gaps](https://github.com/nasa/openmct/issues/4973)
## Troubleshooting CI
The following is an evolving guide to troubleshoot CI and PR issues.
### Github Checks failing
There are a few reasons that your GitHub PR could be failing beyond simple failed tests.
* Required Checks. We're leveraging required checks in GitHub so that we can quickly and precisely control what becomes and informational failure vs a hard requirement. The only way to determine the difference between a required vs information check is check for the `(Required)` emblem next to the step details in GitHub Checks.
* Not all required checks are run per commit. You may need to manually trigger addition GitHub checks with a `pr:<label>` label added to your PR.
### Flaky tests
(CircleCI's test insights feature)[https://circleci.com/blog/introducing-test-insights-with-flaky-test-detection/] collects historical data about the individual test results for both unit and e2e tests. Note: only a 14 day window of flake is available.
### Local=Pass and CI=Fail
Although rare, it is possible that your test can pass locally but fail in CI.
### Reset your workspace
It's possible that you're running with dependencies or a local environment which is out of sync with the branch you're working on. Make sure to execute the following:
```sh
nvm use
npm run clean
npm install
```
#### Run tests in the same container as CI
In extreme cases, tests can fail due to the constraints of running within a container. To execute tests in exactly the same way as run in CircleCI.
```sh
// Replace {X.X.X} with the current Playwright version
// from our package.json or circleCI configuration file
docker run --rm --network host --cpus="2" -v $(pwd):/work/ -w /work/ -it mcr.microsoft.com/playwright:v{X.X.X}-focal /bin/bash
npm install
```
At this point, you're running inside the same container and with 2 cpu cores. You can specify the unit tests:
```sh
npm run test
```
or e2e tests:
```sh
npx playwright test --config=e2e/playwright-ci.config.js --project=chrome --grep <the testcase name>
```

* _Extensions_: Individual units of functionality that can be added to
or removed from Open MCT Web. _Extension categories_ distinguish what
type of functionality is being added/removed.
* _Bundles_: A grouping of related extensions
(named after an analogous concept from [OSGi](http://www.osgi.org/))
that may be added or removed as a group.
The framework layer operates by taking a set of active bundles, and
exposing extensions to one another as-needed, using
[dependency injection](https://en.wikipedia.org/wiki/Dependency_injection).
Extensions are responsible for declaring their dependencies in a
manner which the framework layer can understand.
```nomnoml
#direction: down
[Open MCT Web|
[Dependency injection framework]-->[Platform bundle #1]
[Dependency injection framework]-->[Platform bundle #2]
[Dependency injection framework]-->[Plugin bundle #1]
[Dependency injection framework]-->[Plugin bundle #2]
[Platform bundle #1|[Extensions]]
[Platform bundle #2|[Extensions]]
[Plugin bundle #1|[Extensions]]
[Plugin bundle #2|[Extensions]]
[Platform bundle #1]<->[Platform bundle #2]
[Plugin bundle #1]<->[Platform bundle #2]
[Plugin bundle #1]<->[Plugin bundle #2]
]
```
The "dependency injection framework" in this case is
[AngularJS](https://angularjs.org/). Open MCT Web's framework layer
is really just a thin wrapper over Angular that recognizes the
concepts of bundles and extensions (as declared in JSON files) and
registering extensions with Angular. It additionally acts as a
mediator between Angular and [RequireJS](http://requirejs.org/),
which is used to load JavaScript sources which implement
extensions.
```nomnoml
[Framework layer|
[AngularJS]<-[Framework Component]
[RequireJS]<-[Framework Component]
[Framework Component]1o-*[Bundles]
]
```
It is worth noting that _no other components_ are "aware" of the
framework component directly; Angular and Require are _used by_ the
framework components, and extensions in various bundles will have
their dependencies satisfied by Angular as a consequence of registration
activities which were performed by the framework component.
## Application Initialization
The framework component initializes an Open MCT Web application following
a simple sequence of steps.
```nomnoml
[<start> Start]->[<state> Load bundles.json]
[Load bundles.json]->[<state> Load bundle.json files]
[Load bundle.json files]->[<state> Resolve implementations]
[Resolve implementations]->[<state> Register with Angular]
[Register with Angular]->[<state> Bootstrap application]
[Bootstrap application]->[<end> End]
```
1. __Loading bundles.json.__ A file named `bundles.json` is loaded to determine
which bundles to load. Bundles are given in this file as relative paths
which point to bundle directories.
2. __Load bundle.json files.__ Individual bundle definitions are loaded; a
`bundle.json` file is expected in each bundle directory.
2. __Resolving implementations.__ Any scripts which provide implementations for
extensions exposed by bundles are loaded, using RequireJS.
3. __Register with Angular.__ Resolved extensions are registered with Angular,
such that they can be used by the application at run-time. This stage
includes both registration of Angular built-ins (directives, controllers,
routes, constants, and services) as well as registration of non-Angular
extensions.
4. __Bootstrap application.__ Once all extensions have been registered,
the Angular application
[is bootstrapped](https://docs.angularjs.org/guide/bootstrap).
## Architectural Paradigm
```nomnoml
[Extension]
[Extension]o->[Dependency #1]
[Extension]o->[Dependency #2]
[Extension]o->[Dependency #3]
```
Open MCT Web's architecture relies on a simple premise: Individual units
(extensions) only have access to the dependencies they declare that they
need, and they acquire references to these dependencies via dependency
injection. This has several desirable traits:
* Programming to an interface is enforced. Any given dependency can be
swapped out for something which exposes an equivalent interface. This
improves flexibility against refactoring, simplifies testing, and
provides a common mechanism for extension and reconfiguration.
* The dependencies of a unit must be explicitly defined. This means that
it can be easily determined what a given unit's role is within the
larger system, in terms of what other components it will interact with.
It also helps to enforce good separation of concerns: When a set of
declared dependencies becomes long it is obvious, and this is usually
a sign that a given unit is involved in too many concerns and should
be refactored into smaller pieces.
* Individual units do not need to be aware of the framework; they need
only be aware of the interfaces to the components they specifically
use. This avoids introducing a ubiquitous dependency upon the framework
layer itself; it is plausible to modify or replace the framework
without making changes to individual software components which run upon
the framework.
A drawback to this approach is that it makes it difficult to define
"the architecture" of Open MCT Web, in terms of describing the specific
units that interact at run-time. The run-time architecture is determined
by the framework as the consequence of wiring together dependencies.
As such, the specific architecture of any given application built on
Open MCT Web can look very different.
Keeping that in mind, there are a few useful patterns supported by the
framework that are useful to keep in mind.
The specific service infrastructure provided by the platform is described
in the [Platform Architecture](Platform.md).
## Extension Categories
One of the capabilities that the framework component layers on top of
AngularJS is support for many-to-one dependencies. That is, a specific
extension may declare a dependency to _all extensions of a specific
category_, instead of being limited to declaring specific dependencies.
```nomnoml
#direction: right
[Specific Extension] 1 o-> * [Extension of Some Category]
```
This is useful for introducing specific extension points to an application.
Some unit of software will depend upon all extensions of a given category
and integrate their behavior into the system in some fashion; plugin authors
can then add new extensions of that category to augment existing behaviors.
Some developers may be familiar with the use of registries to achieve
similar characteristics. This approach is similar, except that the registry
is effectively implicit whenever a new extension category is used or
depended-upon. This has some advantages over a more straightforward
registry-based approach:
* These many-to-one relationships are expressed as dependencies; an
extension category is registered as having dependencies on all individual
extensions of this category. This avoids ordering issues that may occur
with more conventional registries, which may be observed before all
dependencies are resolved.
* The need for service registries of specific types is removed, reducing
the number of interfaces to manage within the system. Groups of
extensions are provided as arrays.
## Composite Services
Composite services (registered via extension category `components`) are
a pattern supported by the framework. These allow service instances to
be built from multiple components at run-time; support for this pattern
allows additional bundles to introduce or modify behavior associated
with these services without modifying or replacing original service
instances.
```nomnoml
#direction: down
[<abstract> FooService]
[FooDecorator #1]--:>[FooService]
[FooDecorator #n]--:>[FooService]
[FooAggregator]--:>[FooService]
[FooProvider #1]--:>[FooService]
[FooProvider #n]--:>[FooService]
[FooDecorator #1]o->[<state> ...decorators...]
[...decorators...]o->[FooDecorator #n]
[FooDecorator #n]o->[FooAggregator]
[FooAggregator]o->[FooProvider #1]
[FooAggregator]o->[<state> ...providers...]
[FooAggregator]o->[FooProvider #n]
[FooDecorator #1]--[<note> Exposed as fooService]
```
In this pattern, components all implement an interface which is
standardized for that service. Components additionally declare
that they belong to one of three types:
* __Providers.__ A provider actually implements the behavior
(satisfies the contract) for that kind of service. For instance,
if a service is responsible for looking up documents by an identifier,
one provider may do so by querying a database, while another may
do so by reading a static JSON document. From the outside, either
provider would look the same (they expose the same interface) and
they could be swapped out easily.
* __Aggregator.__ An aggregator takes many providers and makes them
behave as one. Again, this implements the same interface as an
individual provider, so users of the service do not need to be
concerned about the difference between consulting many providers
and consulting one. Continuing with the example of a service that
looks up documents by identifiers, an aggregator here might consult
all providers, and return any document is found (perhaps picking one
over the other or merging documents if there are multiple matches.)
* __Decorators.__ A decorator exposes the same interface as other
components, but instead of fully implementing the behavior associated
with that kind of service, it only acts as an intermediary, delegating
the actual behavior to a different component. Decorators may transform
inputs or outputs, or initiate some side effects associated with a
service. This is useful if certain common behavior associated with a
service (caching, for instance) may be useful across many different
implementations of that same service.
The framework will register extensions in this category such that an
aggregator will depend on all of its providers, and decorators will
depend upon on one another in a chain. The result of this compositing step
(the last decorator, if any; otherwise the aggregator, if any;
otherwise a single provider) will be exposed as a single service that
other extensions can acquire through dependency injection. Because all
components of the same type of service expose the same interface, users
of that service do not need to be aware that they are talking to an
aggregator or a provider, for instance.

# Introduction
The purpose of this document is to familiarize developers with the
overall architecture of Open MCT Web.
The target audience includes:
* _Platform maintainers_: Individuals involved in developing,
extending, and maintaing capabilities of the platform.
* _Integration developers_: Individuals tasked with integrated
Open MCT Web into a larger system, who need to understand
its inner workings sufficiently to complete this integration.
As the focus of this document is on architecture, whenever possible
implementation details (such as relevant API or JSON syntax) have been
omitted. These details may be found in the developer guide.
# Overview
Open MCT Web is client software: It runs in a web browser and
provides a user interface, while communicating with various
server-side resources through browser APIs.
```nomnoml
#direction: right
[Client|[Browser|[Open MCT Web]->[Browser APIs]]]
[Server|[Web services]]
[Client]<->[Server]
```
While Open MCT Web can be configured to run as a standalone client,
this is rarely very useful. Instead, it is intended to be used as a
display and interaction layer for information obtained from a
variety of back-end services. Doing so requires authoring or utilizing
adapter plugins which allow Open MCT Web to interact with these services.
Typically, the pattern here is to provide a known interface that
Open MCT Web can utilize, and implement it such that it interacts with
whatever back-end provides the relevant information.
Examples of back-ends that can be utilized in this fashion include
databases for the persistence of user-created objects, or sources of
telemetry data.
## Software Architecture
The simplest overview of Open MCT Web is to look at it as a "layered"
architecture, where each layer more clearly specifies the behavior
of the software.
```nomnoml
#direction: down
[Open MCT Web|
[Platform]<->[Application]
[Framework]->[Application]
[Framework]->[Platform]
]
```
These layers are:
* [_Framework_](framework.md): The framework layer is responsible for
managing the interactions between application components. It has no
application-specific knowledge; at this layer, we have only
established an abstraction by which different software components
may communicate and/or interact.
* [_Platform_](platform.md): The platform layer defines the general look,
feel, and behavior of Open MCT Web. This includes user-facing components like
Browse mode and Edit mode, as well as underlying elements of the
information model and the general service infrastructure.
* _Application_: The application layer defines specific features of
an application built on Open MCT Web. This includes adapters to
specific back-ends, new types of things for users to create, and
new ways of visualizing objects within the system. This layer
typically consists of a mix of custom plug-ins to Open MCT Web,
as well as optional features (such as Plot view) included alongside
the platform.

# Overview
The Open MCT Web platform utilizes the [framework layer](Framework.md)
to provide an extensible baseline for applications which includes:
* A common user interface (and user interface paradigm) for dealing with
domain objects of various sorts.
* A variety of extension points for introducing new functionality
of various kinds within the context of the common user interface.
* A service infrastructure to support building additional components.
## Platform Architecture
While the framework provides a more general architectural paradigm for
building application, the platform adds more specificity by defining
additional extension types and allowing for integration with back end
components.
The run-time architecture of an Open MCT Web application can be categorized
into certain high-level tiers:
```nomnoml
[DOM]->[<state> AngularJS]
[AngularJS]->[Presentation Layer]
[Presentation Layer]->[Information Model]
[Presentation Layer]->[Service Infrastructure]
[Information Model]->[Service Infrastructure]
[Service Infrastructure]->[<state> Browser APIs]
[Browser APIs]->[Back-end]
```
Applications built using Open MCT Web may add or configure functionality
in __any of these tiers__.
* _DOM_: The rendered HTML document, composed from HTML templates which
have been processed by AngularJS and will be updated by AngularJS
to reflect changes from the presentation layer. User interactions
are initiated from here and invoke behavior in the presentation layer. HTML 
templates are written in Angulars template syntax; see the [Angular documentation on templates](https://docs.angularjs.org/guide/templates). 
These describe the page as actually seen by the user. Conceptually, 
stylesheets (controlling the look­and­feel of the rendered templates) belong 
in this grouping as well. 
* [_Presentation layer_](#presentation-layer): The presentation layer
is responsible for updating (and providing information to update)
the displayed state of the application. The presentation layer consists
primarily of _controllers_ and _directives_. The presentation layer is
concerned with inspecting the information model and preparing it for
display.
* [_Information model_](#information-model): Provides a common (within Open MCT 
Web) set of interfaces for dealing with “things” ­ domain objects ­ within the 
system. User­facing concerns in a Open MCT Web application are expressed as 
domain objects; examples include folders (used to organize other domain 
objects), layouts (used to build displays), or telemetry points (used as 
handles for streams of remote measurements.) These domain objects expose a 
common set of interfaces to allow reusable user interfaces to be built in the 
presentation and template tiers; the specifics of these behaviors are then 
mapped to interactions with underlying services. 
* [_Service infrastructure_](#service-infrastructure): The service
infrastructure is responsible for providing the underlying general
functionality needed to support the information model. This includes
exposing underlying sets of extensions and mediating with the
back-end.
* _Back-end_: The back-end is out of the scope of Open MCT Web, except
for the interfaces which are utilized by adapters participating in the
service infrastructure. Includes the underlying persistence stores, telemetry 
streams, and so forth which the Open MCT Web client is being used to interact 
with.
## Application Start-up
Once the
[application has been initialized](Framework.md#application-initialization)
Open MCT Web primarily operates in an event-driven paradigm; various
events (mouse clicks, timers firing, receiving responses to XHRs) trigger
the invocation of functions, typically in the presentation layer for
user actions or in the service infrastructure for server responses.
The "main point of entry" into an initialized Open MCT Web application
is effectively the
[route](https://docs.angularjs.org/api/ngRoute/service/$route#example)
which is associated with the URL used to access Open MCT Web (or a
default route.) This route will be associated with a template which
will be displayed; this template will include references to directives
and controllers which will be interpreted by Angular and used to
initialize the state of the display in a manner which is backed by
both the information model and the service infrastructure.
```nomnoml
[<start> Start]->[<state> page load]
[page load]->[<state> route selection]
[route selection]->[<state> compile, display template]
[compile, display template]->[Template]
[Template]->[<state> use Controllers]
[Template]->[<state> use Directives]
[use Controllers]->[Controllers]
[use Directives]->[Directives]
[Controllers]->[<state> consult information model]
[consult information model]->[<state> expose data]
[expose data]->[Angular]
[Angular]->[<state> update display]
[Directives]->[<state> add event listeners]
[Directives]->[<state> update display]
[add event listeners]->[<end> End]
[update display]->[<end> End]
```
# Presentation Layer
The presentation layer of Open MCT Web is responsible for providing
information to display within templates, and for handling interactions
which are initiated from templated DOM elements. AngularJS acts as
an intermediary between the web page as the user sees it, and the
presentation layer implemented as Open MCT Web extensions.
```nomnoml
[Presentation Layer|
[Angular built-ins|
[routes]
[controllers]
[directives]
[templates]
]
[Domain object representation|
[views]
[representations]
[representers]
[gestures]
]
]
```
## Angular built-ins
Several extension categories in the presentation layer map directly
to primitives from AngularJS:
* [_Controllers_](https://docs.angularjs.org/guide/controller) provide
data to templates, and expose functionality that can be called from
templates.
* [_Directives_](https://docs.angularjs.org/guide/directive) effectively
extend HTML to provide custom behavior associated with specific
attributes and tags.
* [_Routes_](https://docs.angularjs.org/api/ngRoute/service/$route#example)
are used to associate specific URLs (including the fragment identifier)
with specific application states. (In Open MCT Web, these are used to
describe the mode of usage - e.g. browse or edit - as well as to
identify the object being used.)
* [_Templates_](https://docs.angularjs.org/guide/templates) are partial
HTML documents that will be rendered and kept up-to-date by AngularJS.
Open MCT Web introduces a custom `mct-include` directive which acts
as a wrapper around `ng-include` to allow templates to be referred
to by symbolic names.
## Domain object representation
The remaining extension categories in the presentation layer are specific
to displaying domain objects.
* _Representations_ are templates that will be used to display
domain objects in specific ways (e.g. "as a tree node.")
* _Views_ are representations which are exposed to the user as options
for displaying domain objects.
* _Representers_ are extensions which modify or augment the process
of representing domain objects generally (e.g. by attaching
gestures to them.)
* _Gestures_ provide associations between specific user actions
(expressed as DOM events) and resulting behavior upon domain objects
(typically expressed as members of the `actions` extension category)
that can be reused across domain objects. For instance, `drag` and
`drop` are both gestures associated with using drag-and-drop to
modify the composition of domain objects by interacting with their
representations.
# Information Model
```nomnoml
#direction: right
[Information Model|
[DomainObject|
getId() : string
getModel() : object
getCapability(key : string) : Capability
hasCapability(key : string) : boolean
useCapability(key : string, args...) : *
]
[DomainObject] 1 +- 1 [Model]
[DomainObject] 1 o- * [Capability]
]
```
Domain objects are the most fundamental component of Open MCT Web's
information model. A domain object is some distinct thing relevant to a
user's work flow, such as a telemetry channel, display, or similar.
Open MCT Web is a tool for viewing, browsing, manipulating, and otherwise
interacting with a graph of domain objects.
A domain object should be conceived of as the union of the following:
* _Identifier_: A machine-readable string that uniquely identifies the
domain object within this application instance.
* _Model_: The persistent state of the domain object. A domain object's
model is a JavaScript object that can be losslessly converted to JSON.
* _Capabilities_: Dynamic behavior associated with the domain object.
Capabilities are JavaScript objects which provide additional methods
for interacting with the domain objects which expose those capabilities.
Not all domain objects expose all capabilities. The interface exposed
by any given capability will depend on its type (as identified
by the `key` argument.) For instance, a `persistence` capability
has a different interface from a `telemetry` capability. Using
capabilities requires some prior knowledge of their interface.
## Capabilities and Services
```nomnoml
#direction: right
[DomainObject]o-[FooCapability]
[FooCapability]o-[FooService]
[FooService]o-[foos]
```
At run-time, the user is primarily concerned with interacting with
domain objects. These interactions are ultimately supported via back-end
services, but to allow customization per-object, these are often mediated
by capabilities.
A common pattern that emerges in the Open MCT Platform is as follows:
* A `DomainObject` has some particular behavior that will be supported
by a service.
* A `Capability` of that domain object will define that behavior,
_for that domain object_, supported by a service.
* A `Service` utilized by that capability will perform the actual behavior.
* An extension category will be utilized by that capability to determine
the set of possible behaviors.
Concrete examples of capabilities which follow this pattern
(or a subset of this pattern) include:
```nomnoml
#direction: right
[DomainObject]1 o- *[Capability]
[Capability]<:--[TypeCapability]
[Capability]<:--[ActionCapability]
[Capability]<:--[PersistenceCapability]
[Capability]<:--[TelemetryCapability]
[TypeCapability]o-[TypeService]
[TypeService]o-[types]
[ActionCapability]o-[ActionService]
[ActionService]o-[actions]
[PersistenceCapability]o-[PersistenceService]
[TelemetryCapability]o-[TelemetryService]
```
# Service Infrastructure
Most services exposed by the Open MCT Web platform follow the
[composite services](Framework.md#composite-services) to permit
a higher degree of flexibility in how a service can be modified
or customized for specific applications.
To simplify usage for plugin developers, the platform also usually
includes a provider implementation for these service type that consumes
some extension category. For instance, an `ActionService` provider is
included which depends upon extension category `actions`, and exposes
all actions declared as such to the system. As such, plugin developers
can simply implement the new actions they wish to be made available without
worrying about the details of composite services or implementing a new
`ActionService` provider; however, the ability to implement a new provider
remains useful when the expressive power of individual extensions is
insufficient.
```nomnoml
[ Service Infrastructure |
[ObjectService]->[ModelService]
[ModelService]->[PersistenceService]
[ObjectService]->[CapabilityService]
[CapabilityService]->[capabilities]
[capabilities]->[TelemetryService]
[capabilities]->[PersistenceService]
[capabilities]->[TypeService]
[capabilities]->[ActionService]
[capabilities]->[ViewService]
[PersistenceService]->[<database> Document store]
[TelemetryService]->[<database> Telemetry source]
[ActionService]->[actions]
[ActionService]->[PolicyService]
[ViewService]->[PolicyService]
[ViewService]->[views]
[PolicyService]->[policies]
[TypeService]->[types]
]
```
A short summary of the roles of these services:
* _[ObjectService](#object-service)_: Allows retrieval of domain objects by
their identifiers; in practice, often the main point of entry into the
[information model](#information-model).
* _[ModelService](#model-service)_: Provides domain object models, retrieved
by their identifier.
* _[CapabilityService](#capability-service)_: Provides capabilities, as they
apply to specific domain objects (as judged from their model.)
* _[TelemetryService](#telemetry-service)_: Provides access to historical
and real-time telemetry data.
* _[PersistenceService](#persistence-service)_: Provides the ability to
store and retrieve documents (such as domain object models.)
* _[ActionService](#action-service)_: Provides distinct user actions that
can take place within the system (typically, upon or using domain objects.)
* _[ViewService](#view-service)_: Provides views for domain objects. A view
is a user-selectable representation of a domain object (in practice, an
HTML template.)
* _[PolicyService](#policy-service)_: Handles decisions about which
behavior are allowed within certain specific contexts.
* _[TypeService](#type-service)_: Provides information to distinguish
different types of domain objects from one another within the system.
## Object Service
```nomnoml
#direction: right
[<abstract> ObjectService|
getObjects(ids : Array.<string>) : Promise.<object.<string, DomainObject>>
]
[DomainObjectProvider]--:>[ObjectService]
[DomainObjectProvider]o-[ModelService]
[DomainObjectProvider]o-[CapabilityService]
```
As domain objects are central to Open MCT Web's information model,
acquiring domain objects is equally important.
```nomnoml
#direction: right
[<start> Start]->[<state> Look up models]
[<state> Look up models]->[<state> Look up capabilities]
[<state> Look up capabilities]->[<state> Instantiate DomainObject]
[<state> Instantiate DomainObject]->[<end> End]
```
Open MCT Web includes an implementation of an `ObjectService` which
satisfies this capability by:
* Consulting the [Model Service](#model-service) to acquire domain object
models by identifier.
* Passing these models to a [Capability Service](#capability-service) to
determine which capabilities are applicable.
* Combining these results together as [DomainObject](#information-model)
instances.
## Model Service
```nomnoml
#direction: down
[<abstract> ModelService|
getModels(ids : Array.<string>) : Promise.<object.<string, object>>
]
[StaticModelProvider]--:>[ModelService]
[RootModelProvider]--:>[ModelService]
[PersistedModelProvider]--:>[ModelService]
[ModelAggregator]--:>[ModelService]
[CachingModelDecorator]--:>[ModelService]
[MissingModelDecorator]--:>[ModelService]
[MissingModelDecorator]o-[CachingModelDecorator]
[CachingModelDecorator]o-[ModelAggregator]
[ModelAggregator]o-[StaticModelProvider]
[ModelAggregator]o-[RootModelProvider]
[ModelAggregator]o-[PersistedModelProvider]
[PersistedModelProvider]o-[PersistenceService]
[RootModelProvider]o-[roots]
[StaticModelProvider]o-[models]
```
The platform's model service is responsible for providing domain object
models (effectively, JSON documents describing the persistent state
associated with domain objects.) These are retrieved by identifier.
The platform includes multiple components of this variety:
* `PersistedModelProvider` looks up domain object models from
a persistence store (the [`PersistenceService`](#persistence-service));
this is how user-created and user-modified
domain object models are retrieved.
* `RootModelProvider` provides domain object models that have been
declared via the `roots` extension category. These will appear at the
top level of the tree hierarchy in the user interface.
* `StaticModelProvider` provides domain object models that have been
declared via the `models` extension category. This is useful for
allowing plugins to expose new domain objects declaratively.
* `ModelAggregator` merges together the results from multiple providers.
If multiple providers return models for the same domain object,
the most recently modified version (as determined by the `modified`
property of the model) is chosen.
* `CachingModelDecorator` caches model instances in memory. This
ensures that only a single instance of a domain object model is
present at any given time within the application, and prevent
redundant retrievals.
* `MissingModelDecorator` adds in placeholders when no providers
have returned domain object models for a specific identifier. This
allows the user to easily see that something was expected to be
present, but wasn't.
## Capability Service
```nomnoml
#direction: down
[<abstract> CapabilityService|
getCapabilities(model : object) : object.<string, Function>
]
[CoreCapabilityProvider]--:>[CapabilityService]
[QueuingPersistenceCapabilityDecorator]--:>[CapabilityService]
[CoreCapabilityProvider]o-[capabilities]
[QueuingPersistenceCapabilityDecorator]o-[CoreCapabilityProvider]
```
The capability service is responsible for determining which capabilities
are applicable for a given domain object, based on its model. Primarily,
this is handled by the `CoreCapabilityProvider`, which examines
capabilities exposed via the `capabilities` extension category.
Additionally, `platform/persistence/queue` decorates the persistence
capability specifically to batch persistence attempts among multiple
objects (this allows failures to be recognized and handled in groups.)
## Telemetry Service
```nomnoml
[<abstract> TelemetryService|
requestData(requests : Array.<TelemetryRequest>) : Promise.<object>
subscribe(requests : Array.<TelemetryRequest>) : Function
]<--:[TelemetryAggregator]
```
The telemetry service is responsible for acquiring telemetry data.
Notably, the platform does not include any providers for
`TelemetryService`; applications built on Open MCT Web will need to
implement a provider for this service if they wish to expose telemetry
data. This is usually the most important step for integrating Open MCT Web
into an existing telemetry system.
Requests for telemetry data are usually initiated in the
[presentation layer](#presentation-layer) by some `Controller` referenced
from a view. The `telemetryHandler` service is most commonly used (although
one could also use an object's `telemetry` capability directly) as this
handles capability delegation, by which a domain object such as a Telemetry
Panel can declare that its `telemetry` capability should be handled by the
objects it contains. Ultimately, the request for historical data and the
new subscriptions will reach the `TelemetryService`, and, by way of the
provider(s) which are present for that `TelemetryService`, will pass the
same requests to the back-end.
```nomnoml
[<start> Start]->[Controller]
[Controller]->[<state> declares object of interest]
[declares object of interest]->[TelemetryHandler]
[TelemetryHandler]->[<state> requests telemetry from capabilities]
[TelemetryHandler]->[<state> subscribes to telemetry using capabilities]
[requests telemetry from capabilities]->[TelemetryCapability]
[subscribes to telemetry using capabilities]->[TelemetryCapability]
[TelemetryCapability]->[<state> requests telemetry]
[TelemetryCapability]->[<state> subscribes to telemetry]
[requests telemetry]->[TelemetryService]
[subscribes to telemetry]->[TelemetryService]
[TelemetryService]->[<state> issues request]
[TelemetryService]->[<state> updates subscriptions]
[TelemetryService]->[<state> listens for real-time data]
[issues request]->[<database> Telemetry Back-end]
[updates subscriptions]->[Telemetry Back-end]
[listens for real-time data]->[Telemetry Back-end]
[Telemetry Back-end]->[<end> End]
```
The back-end, in turn, is expected to provide whatever historical
telemetry is available to satisfy the request that has been issue.
```nomnoml
[<start> Start]->[<database> Telemetry Back-end]
[Telemetry Back-end]->[<state> transmits historical telemetry]
[transmits historical telemetry]->[TelemetryService]
[TelemetryService]->[<state> packages telemetry, fulfills requests]
[packages telemetry, fulfills requests]->[TelemetryCapability]
[TelemetryCapability]->[<state> unpacks telemetry per-object, fulfills request]
[unpacks telemetry per-object, fulfills request]->[TelemetryHandler]
[TelemetryHandler]->[<state> exposes data]
[TelemetryHandler]->[<state> notifies controller]
[exposes data]->[Controller]
[notifies controller]->[Controller]
[Controller]->[<state> prepares data for template]
[prepares data for template]->[Template]
[Template]->[<state> displays data]
[displays data]->[<end> End]
```
One peculiarity of this approach is that we package many responses
together at once in the `TelemetryService`, then unpack these in the
`TelemetryCapability`, then repackage these in the `TelemetryHandler`.
The rationale for this is as follows:
* In the `TelemetryService`, we want to have the ability to combine
multiple requests into one call to the back-end, as many back-ends
will support this. It follows that we give the response as a single
object, packages in a manner that allows responses to individual
requests to be easily identified.
* In the `TelemetryCapability`, we want to provide telemetry for a
_single object_, so the telemetry data gets unpacked. This allows
for the unpacking of data to be handled in a single place, and
also permits a flexible substitution method; domain objects may have
implementations of the `telemetry` capability that do not use the
`TelemetryService` at all, while still maintaining compatibility
with any presentation layer code written to utilize this capability.
(This is true of capabilities generally.)
* In the `TelemetryHandler`, we want to group multiple responses back
together again to make it easy for the presentation layer to consume.
In this case, the grouping is different from what may have occurred
in the `TelemetryService`; this grouping is based on what is expected
to be useful _in a specific view_. The `TelemetryService`
may be receiving requests from multiple views.
```nomnoml
[<start> Start]->[<database> Telemetry Back-end]
[Telemetry Back-end]->[<state> notifies client of new data]
[notifies client of new data]->[TelemetryService]
[TelemetryService]->[<choice> relevant subscribers?]
[relevant subscribers?] yes ->[<state> notify subscribers]
[relevant subscribers?] no ->[<state> ignore]
[ignore]->[<end> Ignored]
[notify subscribers]->[TelemetryCapability]
[TelemetryCapability]->[<state> notify listener]
[notify listener]->[TelemetryHandler]
[TelemetryHandler]->[<state> exposes data]
[TelemetryHandler]->[<state> notifies controller]
[exposes data]->[Controller]
[notifies controller]->[Controller]
[Controller]->[<state> prepares data for template]
[prepares data for template]->[Template]
[Template]->[<state> displays data]
[displays data]->[<end> End]
```
The flow of real-time data is similar, and is handled by a sequence
of callbacks between the presentation layer component which is
interested in data and the telemetry service. Providers in the
telemetry service listen to the back-end for new data (via whatever
mechanism their specific back-end supports), package this data in
the same manner as historical data, and pass that to the callbacks
which are associated with relevant requests.
## Persistence Service
```nomnoml
#direction: right
[<abstract> PersistenceService|
listSpaces() : Promise.<Array.<string>>
listObjects() : Promise.<Array.<string>>
createObject(space : string, key : string, document : object) : Promise.<boolean>
readObject(space : string, key : string, document : object) : Promise.<object>
updateObject(space : string, key : string, document : object) : Promise.<boolean>
deleteObject(space : string, key : string, document : object) : Promise.<boolean>
]
[ElasticPersistenceProvider]--:>[PersistenceService]
[ElasticPersistenceProvider]->[<database> ElasticSearch]
[CouchPersistenceProvider]--:>[PersistenceService]
[CouchPersistenceProvider]->[<database> CouchDB]
```
Closely related to the notion of domain objects models is their
persistence. The `PersistenceService` allows these to be saved
and loaded. (Currently, this capability is only used for domain
object models, but the interface has been designed without this idea
in mind; other kinds of documents could be saved and loaded in the
same manner.)
There is no single definitive implementation of a `PersistenceService` in
the platform. Optional adapters are provided to store and load documents
from CouchDB and ElasticSearch, respectively; plugin authors may also
write additional adapters to utilize different back end technologies.
## Action Service
```nomnoml
[ActionService|
getActions(context : ActionContext) : Array.<Action>
]
[ActionProvider]--:>[ActionService]
[CreateActionProvider]--:>[ActionService]
[ActionAggregator]--:>[ActionService]
[LoggingActionDecorator]--:>[ActionService]
[PolicyActionDecorator]--:>[ActionService]
[LoggingActionDecorator]o-[PolicyActionDecorator]
[PolicyActionDecorator]o-[ActionAggregator]
[ActionAggregator]o-[ActionProvider]
[ActionAggregator]o-[CreateActionProvider]
[ActionProvider]o-[actions]
[CreateActionProvider]o-[TypeService]
[PolicyActionDecorator]o-[PolicyService]
```
Actions are discrete tasks or behaviors that can be initiated by a user
upon or using a domain object. Actions may appear as menu items or
buttons in the user interface, or may be triggered by certain gestures.
Responsibilities of platform components of the action service are as
follows:
* `ActionProvider` exposes actions registered via extension category
`actions`, supporting simple addition of new actions. Actions are
filtered down to match action contexts based on criteria defined as
part of an action's extension definition.
* `CreateActionProvider` provides the various Create actions which
populate the Create menu. These are driven by the available types,
so do not map easily ot extension category `actions`; instead, these
are generated after looking up which actions are available from the
[`TypeService`](#type-service).
* `ActionAggregator` merges together actions from multiple providers.
* `PolicyActionDecorator` enforces the `action` policy category by
filtering out actions which violate this policy, as determined by
consulting the [`PolicyService`](#policy-service).
* `LoggingActionDecorator` wraps exposed actions and writes to the
console when they are performed.
## View Service
```nomnoml
[ViewService|
getViews(domainObject : DomainObject) : Array.<View>
]
[ViewProvider]--:>[ViewService]
[PolicyViewDecorator]--:>[ViewService]
[ViewProvider]o-[views]
[PolicyViewDecorator]o-[ViewProvider]
```
The view service provides views that are relevant to a specified domain
object. A "view" is a user-selectable visualization of a domain object.
The responsibilities of components of the view service are as follows:
* `ViewProvider` exposes views registered via extension category
`views`, supporting simple addition of new views. Views are
filtered down to match domain objects based on criteria defined as
part of a view's extension definition.
* `PolicyViewDecorator` enforces the `view` policy category by
filtering out views which violate this policy, as determined by
consulting the [`PolicyService`](#policy-service).
## Policy Service
```nomnoml
[PolicyService|
allow(category : string, candidate : object, context : object, callback? : Function) : boolean
]
[PolicyProvider]--:>[PolicyService]
[PolicyProvider]o-[policies]
```
The policy service provides a general-purpose extensible decision-making
mechanism; plugins can add new extensions of category `policies` to
modify decisions of a known category.
Often, the policy service is referenced from a decorator for another
service, to filter down the results of using that service based on some
appropriate policy category.
The policy provider works by looking up all registered policy extensions
which are relevant to a particular _category_, then consulting each in
order to see if they allow a particular _candidate_ in a particular
_context_; the types for the `candidate` and `context` arguments will
vary depending on the `category`. Any one policy may disallow the
decision as a whole.
```nomnoml
[<start> Start]->[<state> is something allowed?]
[is something allowed?]->[PolicyService]
[PolicyService]->[<state> look up relevant policies by category]
[look up relevant policies by category]->[<state> consult policy #1]
[consult policy #1]->[Policy #1]
[Policy #1]->[<choice> policy #1 allows?]
[policy #1 allows?] no ->[<state> decision disallowed]
[policy #1 allows?] yes ->[<state> consult policy #2]
[consult policy #2]->[Policy #2]
[Policy #2]->[<choice> policy #2 allows?]
[policy #2 allows?] no ->[<state> decision disallowed]
[policy #2 allows?] yes ->[<state> consult policy #3]
[consult policy #3]->[<state> ...]
[...]->[<state> consult policy #n]
[consult policy #n]->[Policy #n]
[Policy #n]->[<choice> policy #n allows?]
[policy #n allows?] no ->[<state> decision disallowed]
[policy #n allows?] yes ->[<state> decision allowed]
[decision disallowed]->[<end> Disallowed]
[decision allowed]->[<end> Allowed]
```
The policy decision is effectively an "and" operation over the individual
policy decisions: That is, all policies must agree to allow a particular
policy decision, and the first policy to disallow a decision will cause
the entire decision to be disallowed. As a consequence of this, policies
should generally be written with a default behavior of "allow", and
should only disallow the specific circumstances they are intended to
disallow.
## Type Service
```nomnoml
[TypeService|
listTypes() : Array.<Type>
getType(key : string) : Type
]
[TypeProvider]--:>[TypeService]
[TypeProvider]o-[types]
```
The type service provides metadata about the different types of domain
objects that exist within an Open MCT Web application. The platform
implementation reads these types in from extension category `types`
and wraps them in a JavaScript interface.

# Security Guide
Open MCT is a rich client with plugin support that executes as a single page
web application in a browser environment. Security concerns and
vulnerabilities associated with the web as a platform should be considered
before deploying Open MCT (or any other web application) for mission or
production usage.
This document describes several important points to consider when developing
for or deploying Open MCT securely. Other resources such as
[Open Web Application Security Project (OWASP)](https://www.owasp.org)
provide a deeper and more general overview of security for web applications.
## Security Model
Open MCT has been architected assuming the following deployment pattern:
* A tagged, tested Open MCT version will be used.
* Externally authored plugins will be installed.
* A server will provide persistent storage, telemetry, and other shared data.
* Authorization, authentication, and auditing will be handled by a server.
## Security Procedures
The Open MCT team secures our code base using a combination of code review,
dependency review, and periodic security reviews. Static analysis performed
during automated verification additionally safeguards against common
coding errors which may result in vulnerabilities.
### Code Review
All contributions are reviewed by internal team members. External
contributors receive increased scrutiny for security and quality,
and must sign a licensing agreement.
### Dependency Review
Before integrating third-party dependencies, they are reviewed for security
and quality, with consideration given to authors and users of these
dependencies, as well as review of open source code.
### Periodic Security Reviews
Open MCT's code, design, and architecture are periodically reviewed
(approximately annually) for common security issues, such as the
[OWASP Top Ten](https://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project).
## Security Concerns
Certain security concerns deserve special attention when deploying Open MCT,
or when authoring plugins.
### Identity Spoofing
Open MCT issues calls to web services with the privileges of a logged in user.
Compromised sources (either for Open MCT itself or a plugin) could
therefore allow malicious code to execute with those privileges.
To avoid this:
* Serve Open MCT and other scripts over SSL (https rather than http)
to prevent man-in-the-middle attacks.
* Exercise precautions such as security reviews for any plugins or
applications built for or with Open MCT to reject malicious changes.
### Information Disclosure
If Open MCT is used to handle or display sensitive data, any components
(such as adapter plugins) must take care to avoid leaking or disclosing
this information. For example, avoid sending sensitive data to third-party
servers or insecure APIs.
### Data Tampering
The web application architecture leaves open the possibility that direct
calls will be made to back-end services, circumventing Open MCT entirely.
As such, Open MCT assumes that server components will perform any necessary
data validation during calls issues to the server.
Additionally, plugins which serialize and write data to the server must
escape that data to avoid database injection attacks, and similar.
### Repudiation
Open MCT assumes that servers log any relevant interactions and associates
these with a user identity; the specific user actions taken within the
application are assumed not to be of concern for auditing.
In the absence of server-side logging, users may disclaim (maliciously,
mistakenly, or otherwise) actions taken within the system without any
way to prove otherwise.
If keeping client-level interactions is important, this will need to be
implemented via a plugin.
### Denial-of-service
Open MCT assumes that server-side components will be insulated against
denial-of-service attacks. Services should only permit resource-intensive
tasks to be initiated by known or trusted users.
### Elevation of Privilege
Corollary to the assumption that servers guide against identity spoofing,
Open MCT assumes that services do not allow a user to act with
inappropriately escalated privileges. Open MCT cannot protect against
such escalation; in the clearest case, a malicious actor could interact
with web services directly to exploit such a vulnerability.
## Additional Reading
The following resources have been used as a basis for identifying potential
security threats to Open MCT deployments in preparation of this document:
* [STRIDE model](https://www.owasp.org/index.php/Threat_Risk_Modeling#STRIDE)
* [Attack Surface Analysis Cheat Sheet](https://www.owasp.org/index.php/Attack_Surface_Analysis_Cheat_Sheet)
* [XSS Prevention Cheat Sheet](https://www.owasp.org/index.php/XSS_(Cross_Site_Scripting)_Prevention_Cheat_Sheet)

# Open MCT Documentation
## Overview
Documentation is provided to support the use and development of
Open MCT. It's recommended that before doing
any development with Open MCT you take some time to familiarize yourself
with the documentation below.
Open MCT provides functionality out of the box, but it's also a platform for
building rich mission operations applications based on modern web technology.
The platform is configured by plugins which extend the platform at a variety
of extension points. The details of how to
extend the platform are provided in the following documentation.
## Sections
* The [API](api/) uses inline documentation.
using [TypeScript](https://www.typescriptlang.org) and some legacy [JSDoc](https://jsdoc.app/). It describes the JavaScript objects and
functions that make up the software platform.
* The [Development Process](process/) document describes the
Open MCT software development cycle.
* The [tutorial](https://github.com/nasa/openmct-tutorial) and [plugin template](https://github.com/nasa/openmct-hello) give examples of extending the platform to add
functionality and integrate with data sources.

# Development Cycle
Development of Open MCT occurs on an iterative cycle of
sprints and releases.
* A _sprint_ is three weeks in duration, and represents a
set of improvements that can be completed and tested by the
development team. Software at the end of the sprint is
"semi-stable"; it will have undergone reduced testing and may carry
defects or usability issues of lower severity, particularly if
there are workarounds.
* A _release_ occurs every four sprints. Releases are stable, and
will have undergone full acceptance testing to ensure that the
software behaves correctly and usably.
## Roles
The sprint process assumes the presence of a __project manager.__
The project manager is responsible for
making tactical decisions about what development work will be
performed, and for coordinating with stakeholders to arrive at
higher-level strategic decisions about desired functionality
and characteristics of the software, major external milestones,
and so forth.
In the absence of a dedicated project manager, this role may be rotated
among members of the development team on a per-sprint basis.
Responsibilities of the project manager including:
* Maintaining (with agreement of stakeholders) a "road map" of work
planned for future releases/sprints; this should be higher-level,
usually expressed as "themes",
with just enough specificity to gauge feasibility of plans,
relate work back to milestones, and identify longer-term
dependencies.
* Determining (with assistance from the rest of the team) which
issues to work on in a given sprint and how they shall be
assigned.
* Pre-planning subsequent sprints to ensure that all members of the
team always have a clear direction.
* Scheduling and/or ensuring adherence to
[process points](#process-points).
* Responding to changes within the sprint (shifting priorities,
new issues) and re-allocating work for the sprint as needed.
## Sprint Calendar
Certain [process points](#process-points) are regularly scheduled in
the sprint cycle.
### Sprints by Release
Allocation of work among sprints should be planned relative to release
goals and milestones. As a general guideline, higher-risk work (large
new features which may carry new defects, major refactoring, design
changes with uncertain effects on usability) should be allocated to
earlier sprints, allowing for time in later sprints to ensure stability.
| Sprint | Focus |
|:------:|:--------------------------------------------------------|
| __1__ | Prototyping, design, experimentation. |
| __2__ | New features, refinements, enhancements. |
| __3__ | Feature completion, low-risk enhancements, bug fixing. |
| __4__ | Stability & quality assurance. |
### Sprints 1-3
The first three sprints of a release are primarily centered around
development work, with regular acceptance testing in the third
week. During this third week, the top priority should be passing
acceptance testing (e.g. by resolving any blockers found); any
resources not needed for this effort should be used to begin work
for the subsequent sprint.
| Week | Mon | Tue | Wed | Thu | Fri |
|:-----:|:-------------------------:|:------:|:---:|:----------------------------:|:-------------------------------------:|
| __1__ | Sprint plan | Tag-up | | | |
| __2__ | | Tag-up | | | Code freeze and sprint branch |
| __3__ | Per-sprint testing | Triage | | _Per-sprint testing*_ | Ship and merge sprint branch to master|
&ast; If necessary.
### Sprint 4
The software must be stable at the end of the fourth sprint; because of
this, the fourth sprint is scheduled differently, with a heightened
emphasis on testing.
| Week | Mon | Tue | Wed | Thu | Fri |
|-------:|:-------------------------:|:------:|:---:|:----------------------------:|:-----------:|
| __1__ | Sprint plan | Tag-up | | | Code freeze |
| __2__ | Per-release testing | Triage | | | |
| __3__ | _Per-release testing*_ | Triage | | _Per-release testing*_ | Ship |
&ast; If necessary.
## Process Points
* __Sprint plan.__ Project manager allocates issues based on
theme(s) for sprint, then reviews with team. Each team member
should have roughly two weeks of work allocated (to allow time
in the third week for testing of work completed.)
* Project manager should also sketch out subsequent sprint so
that team may begin work for that sprint during the
third week, since testing and blocker resolution is unlikely
to require all available resources.
* Testing success criteria identified per issue (where necessary). This could be in the form of acceptance tests on the issue or detailing performance tests, for example.
* __Tag-up.__ Check in and status update among development team.
May amend plan for sprint as-needed.
* __Code freeze.__ Any new work from this sprint
(features, bug fixes, enhancements) must be integrated by the
end of the second week of the sprint. After code freeze, a sprint
branch will be created (and until the end of the sprint) the only
changes that should be merged into the sprint branch should
directly address issues needed to pass acceptance testing.
During this time, any other feature development will continue to
be merged into the master branch for the next sprint.
* __Sprint branch merge to master.__ After acceptance testing, the sprint branch
will be merged back to the master branch. Any code conflicts that
arise will be resolved by the team.
* [__Per-release Testing.__](testing/plan.md#per-release-testing)
Structured testing with predefined
success criteria. No release should ship without passing
acceptance tests. Time is allocated in each sprint for subsequent
rounds of acceptance testing if issues are identified during a
prior round. Specific details of acceptance testing need to be
agreed-upon with relevant stakeholders and delivery recipients,
and should be flexible enough to allow changes to plans
(e.g. deferring delivery of some feature in order to ensure
stability of other features.) Baseline testing includes:
* [__Testathon.__](testing/plan.md#user-testing)
Multi-user testing, involving as many users as
is feasible, plus development team. Open-ended; should verify
completed work from this sprint using the sprint branch, test
exploratory for regressions, et cetera.
* [__Long-Duration Test.__](testing/plan.md#long-duration-testing) A
test to verify that the software remains
stable after running for longer durations. May include some
combination of automated testing and user verification (e.g.
checking to verify that software remains subjectively
responsive at conclusion of test.)
* [__Unit Testing.__](testing/plan.md#unit-testing)
Automated testing integrated into the
build. (These tests are verified to pass more often than once
per sprint, as they run before any merge to master, but still
play an important role in per-release testing.)
* [__Per-sprint Testing.__](testing/plan.md#per-sprint-testing)
Subset of Pre-release Testing
which should be performed before shipping at the end of any
sprint. Time is allocated for a second round of
Pre-release Testing if the first round is not passed. Smoke tests collected from issues/PRs
* __Triage.__ Team reviews issues from acceptance testing and uses
success criteria to determine whether or not they should block
release, then formulates a plan to address these issues before
the next round of acceptance testing. Focus here should be on
ensuring software passes that testing in order to ship on time;
may prefer to disable malfunctioning components and fix them
in a subsequent sprint, for example.
* [__Ship.__](version.md) Tag a code snapshot that has passed release/sprint
testing and deploy that version. (Only true if relevant
testing has passed by this point; if testing has not
been passed, will need to make ad hoc decisions with stakeholders,
e.g. "extend the sprint" or "defer shipment until end of next
sprint.")

The process used to develop Open MCT is described in the following
documents:
* The [Development Cycle](cycle.md) describes how and when specific
process points are repeated during development.
* The [Version Guide](version.md) describes version numbering for

# Release of NASA Open MCT NPM Package
This document outlines the process and key considerations for releasing a new version of the NASA Open MCT project as an NPM (Node Package Manager) package.
## 1. Pre-requisites
Before releasing a new version of the NASA Open MCT NPM package, ensure all dependencies are updated, and comprehensive tests are performed. This ensures compatibility and performance of the Open MCT within the Node.js ecosystem.
## 2. Versioning
Versioning is a critical step for package release. The Open MCT team follows [Semantic Versioning (SemVer)](https://semver.org) that consists of three major components: MAJOR.MINOR.PATCH. These ensure a structured process for updating, bug fixes, backward compatibility, and software progress.
## 3. Changelog Maintenance
A comprehensive changelog file, `CHANGELOG.md`, documents any changes, adding a high level of transparencies for anyone desiring to look into the status of new and past progress. It includes the summation of any major new enhancements, changes, bug fixes, and the credits to the users responsible for each unique progress.
## 4. Notable Changes Labels on GitHub PRs
For the Open MCT package, we leverage GitHub's Pull Request (PR) mechanisms extensively, with three important PR labels dedicated to signifying 'notable_changes':
- **Breaking Change** Highlights the integration of changes that are suspected to break, or without a doubt will break, backward compatibility. These should signal to users the upgrade might be seamless only if dependency and integration factors are properly managed, if not, one should expect to manage atypical technical snags.
- **API change** Signifies when a contribution makes any complete or under layer changes to the communication or its supporting access processes. This label flags required see-through insight on how the web-based control panel sees and manipulates any value and or network logs.
- **Default Behavior Change:** In the incident an update either adjusts a form to or integrates a not previously kept setting or plugin. i.e. autoscale is enabled by default when working with plots.
## 6. Community & Contributions
A flat community and the rounded center are kept in continuous celebration, with the given station open for two open-specifying dialogues, research, and all-for development probing. State the ownership for a handed looped, a welcome for even structure-core and architectural draft and impend.
Thank you for your collaboration and commitment to moving the project onto a text big club.

# Test Plan
## Test Levels
Testing for Open MCT includes:
* _Smoke testing_: Brief, informal testing to verify that no major issues
or regressions are present in the software, or in specific features of
the software.
* _Unit testing_: Automated verification of the performance of individual
software components.
* _User testing_: Testing with a representative user base to verify
that application behaves usably and as specified.
* _Long-duration testing_: Testing which takes place over a long period
of time to detect issues which are not readily noticeable during
shorter test periods.
### Smoke Testing
Manual, non-rigorous testing of the software and/or specific features
of interest. Verifies that the software runs and that basic functionality
is present. The outcome of Smoke Testing should be a simplified list of Acceptance Tests which could be executed by another team member with sufficient context.
### Unit Testing
Unit tests are automated tests which exercise individual software
components. Tests are subject to code review along with the actual
implementation, to ensure that tests are applicable and useful.
Unit tests should meet
[test standards](https://github.com/nasa/openmctweb/blob/master/CONTRIBUTING.md#test-standards)
as described in the contributing guide.
### User Testing
User testing is performed at scheduled times involving target users
of the software or reasonable representatives, along with members of
the development team exercising known use cases. Users test the
software directly; the software should be configured as similarly to
its planned production configuration as is feasible without introducing
other risks (e.g. damage to data in a production instance.)
User testing will focus on the following activities:
* Verifying issues resolved since the last test session.
* Checking for regressions in areas related to recent changes.
* Using major or important features of the software,
as determined by the user.
* General "trying to break things."
During user testing, users will
[report issues](https://github.com/nasa/openmct/issues/new/choose)
as they are encountered.
Desired outcomes of user testing are:
* Identified software defects.
* Areas for usability improvement.
* Feature requests (particularly missed requirements.)
* Recorded issue verification.
### Long-duration Testing
Long-duration testing occurs over a twenty-four hour period. The
software is run in one or more stressing cases representative of expected
usage. After twenty-four hours, the software is evaluated for:
* Performance metrics: Have memory usage or CPU utilization increased
during this time period in unexpected or undesirable ways?
* Subjective usability: Does the software behave in the same way it did
at the start of the test? Is it as responsive?
Any defects or unexpected behavior identified during testing should be
[reported as issues](https://github.com/nasa/openmct/issues/new/choose)
and reviewed for severity.
## Test Performance
Tests are performed at various levels of frequency.
* _Per-merge_: Performed before any new changes are integrated into
the software.
* _Per-sprint_: Performed at the end of every [sprint](../cycle.md).
* _Per-release_: Performed at the end of every [release](../cycle.md).
### Per-merge Testing
Before changes are merged, the author of the changes must perform:
* _Smoke testing_ (both generally, and for areas which interact with
the new changes.)
* _Unit testing_ (as part of the automated build step.)
Changes are not merged until the author has affirmed that both
forms of testing have been performed successfully; this is documented
by the [Author Checklist](https://github.com/nasa/openmctweb/blob/master/CONTRIBUTING.md#author-checklist).
### Per-sprint Testing
Before a sprint is closed, the development team must additionally
perform:
* A relevant subset of [_user testing_](procedures.md#user-test-procedures)
identified by the acting [project manager](../cycle.md#roles).
* [_Long-duration testing_](procedures.md#long-duration-testing)
(specifically, for 24 hours.)
Issues are reported as a product of both forms of testing.
A sprint is not closed until both categories have been performed on
the latest snapshot of the software, _and_ no issues labelled as
["blocker"](https://github.com/nasa/openmctweb/blob/master/CONTRIBUTING.md#issue-reporting)
remain open.
### Per-release Testing
As [per-sprint testing](#per-sprint-testing), except that _user testing_
should cover all test cases, with less focus on changes from the specific
sprint or release.
Per-release testing should also include any acceptance testing steps
agreed upon with recipients of the software.
A release is not closed until both categories have been performed on
the latest snapshot of the software, _and_ no issues labelled as
["blocker" or "critical"](https://github.com/nasa/openmctweb/blob/master/CONTRIBUTING.md#issue-reporting)
remain open.
### Testathons
Testathons can be used as a means of performing per-sprint and per-release testing.
#### Timing
For per-sprint testing, a testathon is typically performed at the beginning of the third week of a sprint, and again later that week to verify any fixes. For per-release testing, a testathon is typically performed prior to any formal testing processes that are applicable to that release.
#### Process
1. Prior to the scheduled testathon, a list will be compiled of all issues that are closed and unverified.
2. For each issue, testers should review the associated PR for testing instructions. See the contributing guide for instructions on [pull requests](https://github.com/nasa/openmct/blob/master/CONTRIBUTING.md#merging).
3. As each issue is verified via testing, any team members testing it should leave a comment on that issue indicating that it has been verified fixed.
4. If a bug is found that relates to an issue being tested, notes should be included on the associated issue, and the issue should be reopened. Bug notes should include reproduction steps.
5. For any bugs that are not obviously related to any of the issues under test, a new issue should be created with details about the bug, including reproduction steps. If unsure about whether a bug relates to an issue being tested, just create a new issue.
6. At the end of the testathon, triage will take place, where all tested issues will be reviewed.
7. If verified fixed, an issue will remain closed, and will have the “unverified” label removed.
8. For any bugs found, a severity will be assigned.
9. A second testathon will be scheduled for later in the week that will aim to address all issues identified as blockers, as well as any other issues scoped by the team during triage.
10. Any issues that were not tested will remain "unverified" and will be picked up in the next testathon.

# Version Guide
This document describes semantics and processes for providing version
numbers for Open MCT, and additionally provides guidelines for dependent
projects developed by the same team.
Versions are incremented at specific points in Open MCT's
[Development Cycle](cycle.md); see that document for a description of
sprints and releases.
## Audience
Individuals interested in consuming version numbers can be categorized as
follows:
* _Users_: Generally disinterested, occasionally wish to identify version
to cross-reference against documentation, or to report issues.
* _Testers_: Want to identify which version of the software they are
testing, e.g. to file issues for defects.
* _Internal developers_: Often, inverse of testers; want to identify which
version of software was/is in use when certain behavior is observed. Want
to be able to correlate versions in use with “streams” of development
(e.g. dev vs. prod), when possible.
* _External developers_: Need to understand which version of software is
in use when developing/maintaining plug-ins, in order to ensure
compatibility of their software.
## Version Reporting
Software versions should be reflected in the user interface of the
application in three ways:
* _Version number_: A semantic version (see below) which serves both to
uniquely identify releases, as well as to inform plug-in developers
about compatibility with previous releases.
* _Revision identifier_: While using git, the commit hash. Supports
internal developers and testers by uniquely identifying client
software snapshots.
* _Branding_: Identifies which variant is in use. (Typically, Open MCT
is re-branded when deployed for a specific mission or center.)
## Version Numbering
Open MCT shall provide version numbers consistent with
[Semantic Versioning 2.0.0](http://semver.org/). In summary, versions
are expressed in a "major.minor.patch" form, and incremented based on
nature of changes to external API. Breaking changes require a "major"
version increment; backwards-compatible changes require a "minor"
version increment; neutral changes (such as bug fixes) require a "patch"
version increment. A hyphen-separated suffix indicates a pre-release
version, which may be unstable or may not fully meet compatibility
requirements.
Additionally, the following project-specific standards will be used:
* During development, a "-next" suffix shall be appended to the
version number. The version number before the suffix shall reflect
the next expected version number for release.
* Prior to a 1.0.0 release, the _minor_ version will be incremented
on a per-release basis; the _patch_ version will be incremented on a
per-sprint basis.
* Starting at version 1.0.0, version numbers will be updated with each
completed sprint. The version number for the sprint shall be
determined relative to the previous released version; the decision
to increment the _major_, _minor_, or _patch_ version should be
made based on the nature of changes during that release. (It is
recommended that these numbers are incremented as changes are
introduced, such that at end of release the version number may
be chosen by simply removing the suffix.)
* The first three sprints in a release may be unstable; in these cases, a
unique version identifier should still be generated, but a suffix
should be included to indicate that the version is not necessarily
production-ready. Recommended suffixes are:
Sprint | Suffix
:------:|:--------:
1 | `-alpha`
2 | `-beta`
3 | `-rc`
### Scope of External API
"External API" refers to the API exposed to, documented for, and used by
plug-in developers. Changes to interfaces used internally by Open MCT
(or otherwise not documented for use externally) require only a _patch_
version bump.
## Incrementing Versions
At the end of a sprint, the [project manager](cycle.md#roles)
should update (or delegate the task of updating) Open MCT version
numbers by the following process:
1. Update version number in `package.json`
1. Checkout branch created for the last sprint that has been successfully tested.
2. Remove a `-next` suffix from the version in `package.json`.
3. Verify that resulting version number meets semantic versioning
requirements relative to previous stable version. Increment the
version number if necessary.
4. If version is considered unstable (which may be the case during
the first three sprints of a release), apply a new suffix per
[Version Numbering](#version-numbering) guidance above.
2. Tag the release.
1. Commit changes to `package.json` on the new branch created in
the previous step.
The commit message should reference the sprint being closed,
preferably by a URL reference to the associated Milestone in
GitHub.
2. Verify that build still completes, that application passes
smoke-testing, and that only differences from tested versions
are the changes to version number above.
3. Push the new branch.
4. Tag this commit with the version number, prepending the letter "v".
(e.g. `git tag v0.9.3-alpha`)
5. Push the tag to GitHub. (e.g. `git push origin v0.9.3-alpha`).
3. Upload a release archive.
1. Use the [GitHub release interface](https://github.com/nasa/openmct/releases)
to draft a new release.
2. Choose the existing tag for the new version (created and pushed above.)
Enter the tag name as the release name as well; see existing releases
for examples. (e.g. `Open MCT v0.9.3-alpha`)
3. Designate the release as a "pre-release" as appropriate (for instance,
when the version number has been suffixed as unstable, or when
the version number is below 1.0.0.)
4. Add release notes including any breaking changes, enhancements,
bug fixes with solutions in brief.
5. Publish the release.
4. Publish the release to npm
1. Login to npm
2. Checkout the tag created in the previous step.
3. In `package.json` change package to be public (private: false)
4. Test the package before publishing by doing `npm publish --dry-run`
if necessary.
5. Publish the package to the npmjs registry (e.g. `npm publish --access public`)
NOTE: Use the `--tag unstable` flag to the npm publish if this is a prerelease.
6. Confirm the package has been published (e.g. `https://www.npmjs.com/package/openmct`)
5. Update snapshot status in `package.json`
1. Create a new branch off the `master` branch.
2. Remove any suffix from the version number,
or increment the _patch_ version if there is no suffix.
3. Append a `-next` suffix.
4. Commit changes to `package.json` on the `master` branch.
The commit message should reference the sprint being opened,
preferably by a URL reference to the associated Milestone in
GitHub.
5. Verify that build still completes, that application passes
smoke-testing.
6. Create a PR to be merged into the `master` branch.
Projects dependent on Open MCT being co-developed by the Open MCT
team should follow a similar process, except that they should
additionally update their dependency on Open MCT to point to the
latest archive when removing their `-next` status, and
that they should be pointed back to the `master` branch after
this has completed.

# e2e testing
This document captures information specific to the e2e testing of Open MCT. For general information about testing, please see [the Open MCT README](https://github.com/nasa/openmct/blob/master/README.md#tests).
## Table of Contents
This document is designed to capture on the What, Why, and How's of writing and running e2e tests in Open MCT. Please use the built-in Github Table of Contents functionality at the top left of this page or the markup.
1. [Getting Started](#getting-started)
2. [Types of Testing](#types-of-e2e-testing)
3. [Architecture](#test-architecture-and-ci)
## Getting Started
While our team does our best to lower the barrier to entry to working with our e2e framework and Open MCT, there is a bit of work required to get from 0 to 1 test contributed.
### Getting started with Playwright
If this is your first time ever using the Playwright framework, we recommend going through the [Getting Started Guide](https://playwright.dev/docs/next/intro) which can be completed in about 15 minutes. This will give you a concise tour of Playwright's functionality and an understanding of the official Playwright documentation which we leverage in Open MCT.
### Getting started with Open MCT's implementation of Playwright
Once you've got an understanding of Playwright, you'll need a baseline understanding of Open MCT:
1. Follow the steps [Building and Running Open MCT Locally](../README.md#building-and-running-open-mct-locally)
2. Once you're serving Open MCT locally, create a 'Display Layout' object. Save it.
3. Create a 'Plot' Object (e.g.: 'Stacked Plot')
4. Create an Example Telemetry Object (e.g.: 'Sine Wave Generator')
5. Expand the Tree and note the hierarchy of objects which were created.
6. Navigate to the Demo Display Layout Object to edit and modify the embedded plot.
7. Modify the embedded plot with Telemetry Data.
What you've created is a display which mimics the display that a mission control operator might use to understand and model telemetry data.
Recreate the steps above with Playwright's codegen tool:
1. `npm run start` in a terminal window to serve Open MCT locally
2. `npx @playwright/test install` to install playwright and dependencies
3. Open another terminal window and start the Playwright codegen application `npx playwright codegen`
4. Navigate the browser to `http://localhost:8080`
5. Click the Create button and notice how your actions in the browser are being recorded in the Playwright Inspector
6. Continue through the steps 2-6 above
What you've created is an automated test which mimics the creation of a mission control display.
Next, you should walk through our implementation of Playwright in Open MCT:
1. Close any terminals which are serving up a local instance of Open MCT
2. Run our 'Getting Started' test in debug mode with `npm run test:e2e:local -- exampleTemplate --debug`
3. Step through each test step in the Playwright Inspector to see how we leverage Playwright's capabilities to test Open MCT
## Types of e2e Testing
e2e testing describes the layer at which a test is performed without prescribing the assertions which are made. Generally, when writing an e2e test, we have five choices to make on an assertion strategy:
1. Functional - Verifies the functional correctness of the application. Sometimes interchanged with e2e or regression testing.
2. Visual - Verifies the "look and feel" of the application and can only detect _undesirable changes when compared to a previous baseline_.
3. Snapshot - Similar to Visual in that it captures the "look" of the application and can only detect _undesirable changes when compared to a previous baseline_. **Generally not preferred due to advanced setup necessary.**
4. Accessibility - Verifies that the application meets the accessibility standards defined by the [WCAG organization](https://www.w3.org/WAI/standards-guidelines/wcag/).
5. Performance - Verifies that application provides a performant experience. Like Snapshot testing, these tests are generally not recommended due to their difficulty in providing a consistent result.
When choosing between the different testing strategies, think only about the assertion that is made at the end of the series of test steps. "I want to verify that the Timer plugin functions correctly" vs "I want to verify that the Timer plugin does not look different than originally designed".
We do not want to interleave visual and functional testing inside the same suite because visual test verification of correctness must happen with a 3rd party service. This service is not available when executing these tests in other contexts (i.e. VIPER).
### Functional Testing
The bulk of our e2e coverage lies in "functional" test coverage which verifies that Open MCT is functionally correct as well as defining _how we expect it to behave_. This enables us to test the application exactly as a user would, while prescribing exactly how a user can interact with the application via a web browser.
### Visual Testing
Visual Testing is an essential part of our e2e strategy as it ensures that the application _appears_ correctly to a user while it compliments the functional e2e suite. It would be impractical to make thousands of assertions functional assertions on the look and feel of the application. Visual testing is interested in getting the DOM into a specified state and then comparing that it has not changed against a baseline.
For a better understanding of the visual issues which affect Open MCT, please see our bug tracker with the `label:visual` filter applied [here](https://github.com/nasa/openmct/issues?q=label%3Abug%3Avisual+)
To read about how to write a good visual test, please see [How to write a great Visual Test](#how-to-write-a-great-visual-test).
`npm run test:e2e:visual` commands will run all of the visual tests against a local instance of Open MCT. If no `PERCY_TOKEN` API key is found in the terminal or command line environment variables, no visual comparisons will be made.
- `npm run test:e2e:visual:ci` will run against every commit and PR.
- `npm run test:e2e:visual:full` will run every night with additional comparisons made for Larger Displays and with the `snow` theme.
#### Percy.io
To make this possible, we're leveraging a 3rd party service, [Percy](https://percy.io/). This service maintains a copy of all changes, users, scm-metadata, and baselines to verify that the application looks and feels the same _unless approved by a Open MCT developer_. To request a Percy API token, please reach out to the Open MCT Dev team on GitHub. For more information, please see the official [Percy documentation](https://docs.percy.io/docs/visual-testing-basics).
At present, we are using percy with two configuration files: `./e2e/.percy.nightly.yml` and `./e2e/.percy.ci.yml`. This is mainly to reduce the number of snapshots.
### Advanced: Snapshot Testing (Not Recommended)
While snapshot testing offers a precise way to detect changes in your application without relying on third-party services like Percy.io, we've found that it doesn't offer any advantages over visual testing in our use-cases. Therefore, snapshot testing is **not recommended** for further implementation.
#### CI vs Manual Checks
Snapshot tests can be reliably executed in Continuous Integration (CI) environments but lack the manual oversight provided by visual testing platforms like Percy.io. This means they may miss issues that a human reviewer could catch during manual checks.
#### Example
A single visual test assertion in Percy.io can be executed across 10 different browser and resolution combinations without additional setup, providing comprehensive testing with minimal configuration. In contrast, a snapshot test is restricted to a single OS and browser resolution, requiring more effort to achieve the same level of coverage.
#### Further Reading
For those interested in the mechanics of snapshot testing with Playwright, you can refer to the [Playwright Snapshots Documentation](https://playwright.dev/docs/test-snapshots). However, keep in mind that we do not recommend using this approach.
#### Open MCT's implementation
- Our Snapshot tests receive a `@snapshot` tag.
- Snapshots need to be executed within the official Playwright container to ensure we're using the exact rendering platform in CI and locally. To do a valid comparison locally:
```sh
// Replace {X.X.X} with the current Playwright version
// from our package.json or circleCI configuration file
docker run --rm --network host -v $(pwd):/work/ -w /work/ -it mcr.microsoft.com/playwright:v{X.X.X}-focal /bin/bash
npm install
npm run test:e2e:checksnapshots
```
### Updating Snapshots
When the `@snapshot` tests fail, they will need to be evaluated to determine if the failure is an acceptable and desireable or an unintended regression.
To compare a snapshot, run a test and open the html report with the 'Expected' vs 'Actual' screenshot. If the actual screenshot is preferred, then the source-controlled 'Expected' snapshots will need to be updated with the following scripts.
```sh
// Replace {X.X.X} with the current Playwright version
// from our package.json or circleCI configuration file
docker run --rm --network host -v $(pwd):/work/ -w /work/ -it mcr.microsoft.com/playwright:v{X.X.X}-focal /bin/bash
npm install
npm run test:e2e:updatesnapshots
```
Once that's done, you'll need to run the following to verify that the changes do not cause more problems:
```sh
npm run test:e2e:checksnapshots
```
## Automated Accessibility (a11y) Testing
Open MCT incorporates accessibility testing through two primary methods to ensure its compliance with accessibility standards:
1. **Usage of Playwright's Locator Strategy**: Open MCT utilizes Playwright's locator strategy, specifically the [page.getByRole('') function](https://playwright.dev/docs/api/class-framelocator#frame-locator-get-by-role), to ensure that web elements are accessible via assistive technologies. This approach focuses on the accessibility of elements rather than full adherence to a11y guidelines, which is covered in the second method.
2. **Enforcing a11y Guidelines with Playwright Axe Plugin**: To rigorously enforce a11y guideline compliance, Open MCT employs the [playwright axe plugin](https://playwright.dev/docs/accessibility-testing). This is achieved through the `scanForA11yViolations` function within the visual testing suite. This method not only benefits from the existing coverage of the visual tests but also targets specific a11y issues, such as `color-contrast` violations, which are particularly pertinent in the context of visual testing.
### a11y Standards (WCAG and Section 508)
Playwright axe supports a wide range of [WCAG Standards](https://playwright.dev/docs/accessibility-testing#scanning-for-wcag-violations) to test against. Open MCT is testing against the [Section 508](https://www.section508.gov/test/testing-overview/) accessibility guidelines with the intent to support higher standards over time. As of 2024, Section508 requirements now map completely to WCAG 2.0 AA. In the future, Section 508 requirements may map to WCAG 2.1 AA.
### Reading an a11y test failure
When an a11y test fails, the result must be interpreted in the html test report or the a11y report json artifact stored in the `/test-results/` folder. The json structure should be parsed for `"violations"` by `"id"` and identified `"target"`. Example provided for the 'color-contrast-enhanced' violation.
```json
"violations":
{
"id": "color-contrast-enhanced",
"impact": "serious",
"html": "<span class=\"label c-indicator__label\">0 Snapshots <button aria-label=\"Show Snapshots\">Show</button></span>",
"target": [
".s-status-off > .label.c-indicator__label"
],
"failureSummary": "Fix any of the following:\n Element has insufficient color contrast of 6.51 (foreground color: #aaaaaa, background color: #262626, font size: 8.1pt (10.8px), font weight: normal). Expected contrast ratio of 7:1"
}
```
## Performance Testing
The open source performance tests function in three ways which match their naming and folder structure:
`tests/performance` - The tests at the root of this folder path detect functional changes which are mostly apparent with large performance regressions like [this](https://github.com/nasa/openmct/issues/6879). These tests run against openmct webpack in `production-mode` with the `npm run test:perf:localhost` script.
`tests/performance/contract/` - These tests serve as [contracts](https://martinfowler.com/bliki/ContractTest.html) for the locator logic, functionality, and assumptions will work in our downstream, closed source test suites. These tests run against openmct webpack in `dev-mode` with the `npm run test:perf:contract` script.
`tests/performance/memory/` - These tests execute memory leak detection checks in various ways. This is expected to evolve as we move to the `memlab` project. These tests run against openmct webpack in `production-mode` with the `npm run test:perf:memory` script.
These tests are expected to become blocking and gating with assertions as we extend the capabilities of Playwright.
In addition to the explicit definition of performance tests, we also ensure that our test timeout timing is "tight" to catch performance regressions detectable by action timeouts. i.e. [Notebooks load much slower than they used to #6459](https://github.com/nasa/openmct/issues/6459)
## Test Architecture and CI
### Architecture
### File Structure
Our file structure follows the type of type of testing being exercised at the e2e layer and files containing test suites which matcher application behavior or our `src` and `example` layout. This area is not well refined as we figure out what works best for closed source and downstream projects. This may change altogether if we move `e2e` to it's own npm package.
|File Path|Description|
|:-:|-|
|`./helper` | Contains helper functions or scripts which are leveraged directly within the test suites (e.g.: non-default plugin scripts injected into the DOM)|
|`./test-data` | Contains test data which is leveraged or generated in the functional, performance, or visual test suites (e.g.: localStorage data).|
|`./tests/functional` | The bulk of the tests are contained within this folder to verify the functionality of Open MCT.|
|`./tests/functional/example/` | Tests which specifically verify the example plugins (e.g.: Sine Wave Generator).|
|`./tests/functional/plugins/` | Tests which loosely test each plugin. This folder is the most likely to change. Note: some `@snapshot` tests are still contained within this structure.|
|`./tests/framework/` | Tests which verify that our testing framework's functionality and assumptions will continue to work based on further refactoring or Playwright version changes (e.g.: verifying custom fixtures and appActions).|
|`./tests/performance/` | Performance tests which should be run on every commit.|
|`./tests/performance/contract/` | A subset of performance tests which are designed to provide a contract between the open source tests which are run on every commit and the downstream tests which are run post merge and with other frameworks.|
|`./tests/performance/memory` | A subset of performance tests which are designed to test for memory leaks.|
|`./tests/visual-a11y/` | Visual tests and accessibility tests.|
|`./tests/visual-a11y/component/` | Visual and accessibility tests which are only run against a single component.|
|`./appActions.js` | Contains common methods which can be leveraged by test case authors to quickly move through the application when writing new tests.|
|`./baseFixture.js` | Contains base fixtures which only extend default `@playwright/test` functionality. The expectation is that these fixtures will be removed as the native Playwright API improves|
Our functional tests end in `*.e2e.spec.js`, visual tests in `*.visual.spec.js` and performance tests in `*.perf.spec.js`.
### Configuration
Where possible, we try to run Open MCT without modification or configuration change so that the Open MCT doesn't fail exclusively in "test mode" or in "production mode".
Open MCT is leveraging the [config file](https://playwright.dev/docs/test-configuration) pattern to describe the capabilities of Open MCT e2e _where_ it's run
|Config File|Description|
|:-:|-|
|`./playwright-ci.config.js` | Used when running in CI or to debug CI issues locally|
|`./playwright-local.config.js` | Used when running locally|
|`./playwright-performance.config.js` | Used when running performance tests in CI or locally|
|`./playwright-performance-devmode.config.js` | Used when running performance tests in CI or locally|
|`./playwright-visual-a11y.config.js` | Used to run the visual and a11y tests in CI or locally|
#### Test Tags
Test tags are a great way of organizing tests outside of a file structure. To learn more see the official documentation [here](https://playwright.dev/docs/test-annotations#tag-tests).
Current list of test tags:
|Test Tag|Description|
|:-:|-|
|`@mobile` | Test case or test suite is compatible with Playwright's iPad support and Open MCT's read-only mobile view (i.e. no create button).|
|`@a11y` | Test case or test suite to execute playwright-axe accessibility checks and generate a11y reports.|
|`@addInit` | Initializes the browser with an injected and artificial state. Useful for loading non-default plugins. Likely will not work outside of `npm start`.|
|`@localStorage` | Captures or generates session storage to manipulate browser state. Useful for excluding in tests which require a persistent backend (i.e. CouchDB). See [note](#utilizing-localstorage)|
|`@snapshot` | Uses Playwright's snapshot functionality to record a copy of the DOM for direct comparison. Must be run inside of the playwright container.|
|`@2p` | Indicates that multiple users are involved, or multiple tabs/pages are used. Useful for testing multi-user interactivity.|
|`@generatedata` | Indicates that a test is used to generate testdata or test the generated test data. Usually to be associated with localstorage, but this may grow over time.|
|`@clock` | A test which modifies the clock. These have expanded out of the visual tests and into the functional tests.
|`@framework` | A test for open mct e2e capabilities. This is primarily to ensure we don't break projects which depend on sourcing this project's fixtures like appActions.js.
### Continuous Integration
The cheapest time to catch a bug is pre-merge. Unfortunately, this is the most expensive time to run all of the tests since each merge event can consist of hundreds of commits. For this reason, we're selective in _what we run_ as much as _when we run it_.
We leverage CircleCI to run tests against each commit and inject the Test Reports which are generated by Playwright so that they team can keep track of flaky and [historical test trends](https://app.circleci.com/insights/github/nasa/openmct/workflows/overall-circleci-commit-status/tests?branch=master&reporting-window=last-30-days)
We leverage Github Actions / Workflows to execute tests as it gives us the ability to run against multiple operating systems with greater control over git event triggers (i.e. Run on a PR Comment event).
Our CI environment consists of 3 main modes of operation:
#### 1. Per-Commit Testing
CircleCI
- e2e tests against ubuntu and chrome
- Performance tests against ubuntu and chrome
- e2e tests are linted
- Visual and a11y tests are run in a single resolution on the default `espresso` theme
#### 2. Per-Merge Testing
Github Actions / Workflow
- Full suite against all browsers/projects. Triggered with Github Label Event 'pr:e2e'
- CouchDB Tests. Triggered on PR Create and again with Github Label Event 'pr:e2e:couchdb'
#### 3. Scheduled / Batch Testing
Nightly Testing in Circle CI
- Full e2e suite against ubuntu and chrome, firefox, and an MMOC resolution profile
- Performance tests against ubuntu and chrome
- CouchDB suite
- Visual and a11y Tests are run in the full profile
Github Actions / Workflow
- None at the moment
#### Parallelism and Fast Feedback
In order to provide fast feedback in the Per-Commit context, we try to keep total test feedback at 5 minutes or less. That is to say, A developer should have a pass/fail result in under 5 minutes.
Playwright has native support for semi-intelligent sharding. Read about it [here](https://playwright.dev/docs/test-parallel#shard-tests-between-multiple-machines).
We will be adjusting the parallelization of the Per-Commit tests to keep below the 5 minute total runtime threshold.
In addition to the Parallelization of Test Runners (Sharding), we're also running two concurrent threads on every Shard. This is the functional limit of what CircleCI Agents can support from a memory and CPU resource constraint.
So for every commit, Playwright is effectively running 4 x 2 concurrent browsercontexts to keep the overall runtime to a miminum.
At the same time, we don't want to waste CI resources on parallel runs, so we've configured each shard to fail after 5 test failures. Test failure logs are recorded and stored to allow fast triage.
### Cross-browser and Cross-operating system
#### **What's supported:**
We are leveraging the `browserslist` project to declare our supported list of browsers. We support macOS, Windows, and ubuntu 20+.
#### **Where it's tested:**
We lint on `browserslist` to ensure that we're not implementing deprecated browser APIs and are aware of browser API improvements over time.
We also have the need to execute our e2e tests across this published list of browsers. Our browsers and browser version matrix is found inside of our `./playwright-*.config.js`, but mostly follows in order of bleeding edge to stable:
- `playwright-chromium channel:beta`
- A beta version of Chromium from official chromium channels. As close to the bleeding edge as we can get.
- `playwright-chromium`
- A stable version of Chromium from the official chromium channels. This is always at least 1 version ahead of desktop chrome.
- `playwright-chrome`
- The stable channel of Chrome from the official chrome channels. This is always 2 versions behind chromium.
- `playwright-firefox`
- Firefox Latest Stable. Modified slightly by the playwright team to support a CDP Shim.
In terms of operating system testing, we're only limited by what the CI providers are able to support. The bulk of our testing is performed on the official playwright container which is based on ubuntu. Github Actions allows us to use `windows-latest` and `mac-latest` and is run as needed.
#### **Mobile**
We have a Mission-need to support iPad and mobile devices. To run our test suites with mobile devices, please see our `playwright-mobile.config.js` projects.
In general, our test suite is not designed to run against mobile devices as the mobile experience is a focused version of the application. Core functionality is missing (chiefly the 'Create' button). To bypass the object creation, we leverage the `storageState` properties for starting the mobile tests with localstorage.
For now, the mobile tests will exist in the /tests/mobile/ suites and be executed with the
```sh
npm run test:e2e:mobile
```
command.
#### **Skipping or executing tests based on browser, os, and/os browser version:**
Conditionally skipping tests based on browser (**RECOMMENDED**):
```js
test('Can adjust image brightness/contrast by dragging the sliders', async ({ page, browserName }) => {
// eslint-disable-next-line playwright/no-skipped-test
test.skip(browserName === 'firefox', 'This test needs to be updated to work with firefox');
// ...
```
Conditionally skipping tests based on OS:
```js
test('Can adjust image brightness/contrast by dragging the sliders', async ({ page }) => {
// eslint-disable-next-line playwright/no-skipped-test
test.skip(process.platform === 'darwin', 'This test needs to be updated to work with MacOS');
// ...
```
Skipping based on browser version (Rarely used): <https://github.com/microsoft/playwright/discussions/17318>
## Test Design, Best Practices, and Tips & Tricks
### Test Design
#### Test as the User
In general, strive to test only through the UI as a user would. As stated in the [Playwright Best Practices](https://playwright.dev/docs/best-practices#test-user-visible-behavior):
> "Automated tests should verify that the application code works for the end users, and avoid relying on implementation details such as things which users will not typically use, see, or even know about such as the name of a function, whether something is an array, or the CSS class of some element. The end user will see or interact with what is rendered on the page, so your test should typically only see/interact with the same rendered output."
By adhering to this principle, we can create tests that are both robust and reflective of actual user experiences.
#### How to make tests robust to function in other contexts (VISTA, COUCHDB, YAMCS, VIPER, etc.)
1. Leverage the use of `appActions.js` methods such as `createDomainObjectWithDefaults()`. This ensures that your tests will create unique instances of objects for your test to interact with.
1. Do not assert on the order or structure of objects available unless you created them yourself. These tests may be used against a persistent datastore like couchdb with many objects in the tree.
1. Do not search for your created objects. Open MCT does not performance uniqueness checks so it's possible that your tests will break when run twice.
1. Avoid creating locator aliases. This likely means that you're compensating for a bad locator. Improve the application instead.
1. Leverage `await page.goto('./', { waitUntil: 'domcontentloaded' });` instead of `{ waitUntil: 'networkidle' }`. Tests run against deployments with websockets often have issues with the networkidle detection.
#### How to make tests faster and more resilient to application changes
1. Avoid app interaction when possible. The best way of doing this is to navigate directly by URL:
```js
// You can capture the CreatedObjectInfo returned from this appAction:
const clock = await createDomainObjectWithDefaults(page, { type: 'Clock' });
// ...and use its `url` property to navigate directly to it later in the test:
await page.goto(clock.url);
```
1. Leverage `await page.goto('./', { waitUntil: 'domcontentloaded' });`
- Initial navigation should _almost_ always use the `{ waitUntil: 'domcontentloaded' }` option.
1. Avoid repeated setup to test a single assertion. Write longer tests with multiple soft assertions.
This ensures that your changes will be picked up with large refactors.
1. Use [user-facing locators](https://playwright.dev/docs/best-practices#use-locators) (Now a eslint rule!)
```js
page.getByRole('button', { name: 'Create' } )
```
Instead of
```js
page.locator('.c-create-button')
```
Note: `page.locator()` can be used in performance tests as xk6-browser does not yet support the new `page.getBy` pattern and css lookups can be [1.5x faster](https://serpapi.com/blog/css-selectors-faster-than-getbyrole-playwright/)
##### Utilizing LocalStorage
1. In order to save test runtime in the case of tests that require a decent amount of initial setup (such as in the case of testing complex displays), you may use [Playwright's `storageState` feature](https://playwright.dev/docs/api/class-browsercontext#browser-context-storage-state) to generate and load localStorage states.
1. To generate a localStorage state to be used in a test:
- Add an e2e test to our generateLocalStorageData suite which sets the initial state (creating/configuring objects, etc.), saving it in the `test-data` folder:
```js
// Save localStorage for future test execution
await context.storageState({
path: path.join(__dirname, '../../../e2e/test-data/display_layout_with_child_layouts.json')
});
```
- Load the state from file at the beginning of the desired test suite (within the `test.describe()`). (NOTE: the storage state will be used for each test in the suite, so you may need to create a new suite):
```js
const LOCALSTORAGE_PATH = path.resolve(
__dirname,
'../../../../test-data/display_layout_with_child_layouts.json'
);
test.use({
storageState: path.resolve(__dirname, LOCALSTORAGE_PATH)
});
```
### How to write a great test
- Avoid using css locators to find elements to the page. Use modern web accessible locators like `getByRole`
- Use our [App Actions](./appActions.js) for performing common actions whenever applicable.
- Use `waitForPlotsToRender()` before asserting against anything that is dependent upon plot series data being loaded and drawn.
- If you create an object outside of using the `createDomainObjectWithDefaults` App Action, make sure to fill in the 'Notes' section of your object with `page.testNotes`:
```js
// Fill the "Notes" section with information about the
// currently running test and its project.
const { testNotes } = page;
const notesInput = page.locator('form[name="mctForm"] #notes-textarea');
await notesInput.fill(testNotes);
```
#### How to Write a Great Visual Test
1. **Look for the Unknown Unknowns**: Avoid asserting on specific differences in the visual diff. Visual tests are most effective for identifying unknown unknowns.
2. **Get the App into Interesting States**: Prioritize getting Open MCT into unusual layouts or behaviors before capturing a visual snapshot. For instance, you could open a dropdown menu.
3. **Expect the Unexpected**: Use functional expect statements only to verify assumptions about the state between steps. A great visual test doesn't fail during the test itself, but rather when changes are reviewed in Percy.io.
4. **Control Variability**: Account for variations inherent in working with time-based telemetry and clocks.
- Utilize `percyCSS` to ignore time-based elements. For more details, consult our [percyCSS file](./.percy.ci.yml).
- Use Open MCT's fixed-time mode unless explicitly testing realtime clock
- Employ the `createExampleTelemetryObject` appAction to source telemetry and specify a `name` to avoid autogenerated names.
- Avoid creating objects with a time component like timers and clocks.
- Utilize the playwright clock() API. See @clock Annotations for examples.
5. **Hide the Tree and Inspector**: Generally, your test will not require comparisons involving the tree and inspector. These aspects are covered in component-specific tests (explained below). To exclude them from the comparison by default, navigate to the root of the main view with the tree and inspector hidden:
- `await page.goto('./#/browse/mine?hideTree=true&hideInspector=true')`
6. **Component-Specific Tests**: If you wish to focus on a particular component, use the `/visual-a11y/component/` folder and limit the scope of the comparison to that component. For instance:
```js
await percySnapshot(page, `Tree Pane w/ single level expanded (theme: ${theme})`, {
scope: treePane
});
```
- Note: The `scope` variable can be any valid CSS selector.
7. **Write many `percySnapshot` commands in a single test**: In line with our approach to longer functional tests, we recommend that many test percySnapshots are taken in a single test. For instance:
```js
//<Some interesting state>
await percySnapshot(page, `Before object expanded (theme: ${theme})`);
//<Click on object>
await percySnapshot(page, `object expanded (theme: ${theme})`);
//Select from object
await percySnapshot(page, `object selected (theme: ${theme})`)
```
8. **Use `networkidle` to wait for network requests to complete**: This is necessary to ensure that all network requests have completed before taking a snapshot. This ensures that icons are loaded and other assets are available. https://github.com/nasa/openmct/issues/7549
#### How to write a great network test
- Where possible, it is best to mock out third-party network activity to ensure we are testing application behavior of Open MCT.
- It is best to be as specific as possible about the expected network request/response structures in creating your mocks.
- Make sure to only mock requests which are relevant to the specific behavior being tested.
- Where possible, network requests and responses should be treated in an order-agnostic manner, as the order in which certain requests/responses happen is dynamic and subject to change.
Some examples of mocking network responses in regards to CouchDB can be found in our [couchdb.e2e.spec.js](./tests/functional/couchdb.e2e.spec.js) test file.
### Best Practices
For now, our best practices exist as self-tested, living documentation in our [exampleTemplate.e2e.spec.js](./tests/framework/exampleTemplate.e2e.spec.js) file.
For best practices with regards to mocking network responses, see our [couchdb.e2e.spec.js](./tests/functional/couchdb.e2e.spec.js) file.
### Tips & Tricks
The following contains a list of tips and tricks which don't exactly fit into a FAQ or Best Practices doc.
- (Advanced) Overriding the Browser's Clock
It is possible to override the browser's clock in order to control time-based elements. Since this can cause unwanted behavior -- i.e. Tree not rendering -- only use this sparingly. Use the `page.clock()` API as such:
```js
import { test, expect } from '../../pluginFixtures.js';
test.describe('foo test suite @clock', () => {
test.beforeEach(async ({ page }) => {
//Set clock time
await page.clock.install({ time: MISSION_TIME });
await page.clock.resume();
//Navigate to page with new clock
await page.goto('./', { waitUntil: 'domcontentloaded' });
});
test('bar here', async ({ page }) => {
/// ...
});
```
- Working with multiple pages
There are instances where multiple browser pages will needed to verify multi-page or multi-tab application behavior. Make sure to use the `@2p` annotation as well as name each page appropriately: i.e. `page1` and `page2` or `tab1` and `tab2` depending on the intended use case. Generally pages should be used unless testing `sharedWorker` code, specifically.
- Working with file downloads and JSON data
Open MCT has the capability of exporting certain objects in the form of a JSON file handled by the chrome browser. The best example of this type of test can be found in the exportAsJson test.
```js
const [download] = await Promise.all([
page.waitForEvent('download'), // Waits for the download event
page.getByLabel('Export as JSON').click() // Triggers the download
]);
// Wait for the download process to complete
const path = await download.path();
// Read the contents of the downloaded file using readFile from fs/promises
const fileContents = await fs.readFile(path, 'utf8');
const jsonData = JSON.parse(fileContents);
// Use the function to retrieve the key
const key = getFirstKeyFromOpenMctJson(jsonData);
// Verify the contents of the JSON file
expect(jsonData.openmct[key]).toHaveProperty('name', 'e2e folder');
```
### Reporting
Test Reporting is done through official Playwright reporters and the CI Systems which execute them.
We leverage the following official Playwright reporters:
- HTML
- junit
- github annotations
- Tracefile
- Screenshots
When running the tests locally with the `npm run test:e2e:local` command, the html report will open automatically on failure. Inside this HTML report will be a complete summary of the finished tests. If the tests failed, you'll see embedded links to screenshot failure, execution logs, and the Tracefile.
When looking at the reports run in CI, you'll leverage this same HTML Report which is hosted either in CircleCI or Github Actions as a build artifact.

### About e2e testing
e2e testing is an industry-standard approach to automating the testing of web-based UIs such as Open MCT. Broadly speaking, e2e tests differentiate themselves from unit tests by preferring replication of real user interactions over execution of raw JavaScript functions.
Historically, the abstraction necessary to replicate real user behavior meant that:
- e2e tests were "expensive" due to how much code each test executed. The closer a test replicates the user, the more code is needed run during test execution. Unit tests could run smaller units of code more efficiently.
- e2e tests were flaky due to network conditions or the underlying protocols associated with testing a browser.
- e2e frameworks relied on a browser communication standard which lacked the observability and controls necessary needed to reach the code paths possible with unit and integration tests.
- e2e frameworks provided insufficient debug information on test failure
However, as the web ecosystem has matured to the point where mission-critical UIs can be written for the web (Open MCT), the e2e testing tools have matured as well. There are now fewer "trade-offs" when choosing to write an e2e test over any other type of test.
Modern e2e frameworks:
- Bypass the surface layer of the web-application-under-test and use a raw debugging protocol to observe and control application and browser state.
- These new browser-internal protocols enable near-instant, bi-directional communication between test code and the browser, speeding up test execution and making the tests as reliable as the application itself.
- Provide test debug tooling which enables developers to pinpoint failure
Furthermore, the abstraction necessary to run e2e tests as a user enables them to be extended to run within a variety of contexts. This matches the extensible design of Open MCT.
A single e2e test in Open MCT is extended to run:
- Against a matrix of browser versions.
- Against a matrix of OS platforms.
- Against a local development version of Open MCT.
- A version of Open MCT loaded as a dependency (VIPER, VISTA, etc)
- Against a variety of data sources or telemetry endpoints.
### Why Playwright?
[Playwright](https://playwright.dev/) was chosen as our e2e framework because it solves a few VIPER Mission needs:
1. First-class support for Automated Performance Testing
2. Official Chrome, Chrome Canary, and iPad Capabilities
3. Support for Browserless.io to run tests in a "hermetically sealed" environment
4. Ability to generate code coverage reports
### FAQ
- How does this help NASA missions?
- When should I write an e2e test instead of a unit test?
- When should I write a functional vs visual test?
- How is Open MCT extending default Playwright functionality?
- What about Component Testing?
### Writing Tests
Playwright provides 3 supported methods of debugging and authoring tests:
- A 'watch mode' for running tests locally and debugging on the fly
- A 'debug mode' for debugging tests and writing assertions against tests
- A 'VSCode plugin' for debugging tests within the VSCode IDE.
Generally, we encourage folks to use the watch mode and provide a script `npm run test:e2e:watch` which launches the launch mode ui and enables hot reloading on the dev server.
### e2e Troubleshooting
Please follow the general guide troubleshooting in [the general troubleshooting doc](../TESTING.md#troubleshooting-ci)
- Tests won't start because 'Error: <http://localhost:8080/># is already used...'
This error will appear when running the tests locally. Sometimes, the webserver is left in an orphaned state and needs to be cleaned up. To clear up the orphaned webserver, execute the following from your Terminal:
```lsof -n -i4TCP:8080 | awk '{print$2}' | tail -1 | xargs kill -9```
### Upgrading Playwright
In order to upgrade from one version of Playwright to another, the version should be updated in several places in both `openmct` and `openmct-yamcs` repos. An easy way to identify these locations is to search for the current version in all files and find/replace.
For reference, all of the locations where the version should be updated are listed below:
#### **In `openmct`:**
- `package.json`
- Both packages `@playwright/test` and `playwright-core` should be updated to the same target version.
- `.circleci/config.yml`
- `.github/workflows/e2e-couchdb.yml`
- `.github/workflows/e2e-pr.yml`
#### **In `openmct-yamcs`:**
- `package.json`
- `@playwright/test` should be updated to the target version.
- `.github/workflows/yamcs-quickstart-e2e.yml`
