+## Types
+
+The Open MCT library includes its own TypeScript declaration files which can be
+used to provide code hints and typechecking in your own Open MCT application.
+
+Open MCT's type declarations are generated via `tsc` from JSDoc-style comment
+blocks. For more information on this, [check out TypeScript's documentation](https://www.typescriptlang.org/docs/handbook/declaration-files/dts-from-js.html).
+
+### Using Types
+
+In order to use Open MCT's provided types in your own application, create a
+`jsconfig.js` at the root of your project with this minimal configuration:
+
+```json
+{
+  "compilerOptions": {
+    "baseUrl": "./",
+      "target": "es6",
+      "checkJs": true,
+      "moduleResolution": "node",
+      "paths": {
+        "openmct": ["node_modules/openmct/dist/openmct.d.ts"]
+      }
+  }
+}
+```
+
+Then, simply import and use `openmct` in your application:
+
+```js
+import openmct from "openmct";
+```
+
+### Limitations
+
+The effort to add types for Open MCT's public API is ongoing, and the provided
+type declarations may be incomplete.
+
+If you would like to contribute types to Open MCT, please check out
+[TypeScript's documentation](https://www.typescriptlang.org/docs/handbook/declaration-files/dts-from-js.html) on generating type declarations from JSDoc-style comment blocks.
+Then read through our [contributing guide](https://github.com/nasa/openmct/blob/f7cf3f72c2efd46da7ce5719c5e52c8806d166f0/CONTRIBUTING.md) and open a PR!

 ###### Value Hints
 
 Each telemetry value description has an object defining hints.  Keys in this object represent the hint itself, and the value represents the weight of that hint.  A lower weight means the hint has a higher priority.  For example, multiple values could be hinted for use as the y-axis of a plot (raw, engineering), but the highest priority would be the default choice.  Likewise, a table will use hints to determine the default order of columns.
 
 Known hints:
 
-* `domain`: Values with a `domain` hint will be used for the x-axis of a plot, and tables will render columns for these values first.
-* `range`: Values with a `range` hint will be used as the y-axis on a plot, and tables will render columns for these values after the `domain` values.
-* `image`: Indicates that the value may be interpreted as the URL to an image file, in which case appropriate views will be made available.
-* `imageDownloadName`: Indicates that the value may be interpreted as the name of the image file.
+- `domain`: Values with a `domain` hint will be used for the x-axis of a plot, and tables will render columns for these values first.
+- `range`: Values with a `range` hint will be used as the y-axis on a plot, and tables will render columns for these values after the `domain` values.

+- `imageDownloadName`: Indicates that the value may be interpreted as the name of the image file.
 
 ##### The Time Conductor and Telemetry
 
 Open MCT provides a number of ways to pivot through data and link data via time.  The Time Conductor helps synchronize multiple views around the same time.
 
-In order for the time conductor to work, there will always be an active "time system".  All telemetry metadata *must* have a telemetry value with a `key` that matches the `key` of the active time system.  You can use the `source` attribute on the value metadata to remap this to a different field in the telemetry datum-- especially useful if you are working with disparate datasources that have different field mappings.

+They have a simple structure, provided here as a TypeScript interface:
 
-* `key`: A `string` that uniquely identifies this formatter.
-* `format`: A `function` that takes a raw telemetry value, and returns a 
-  human-readable `string` representation of that value. It has one required 
-  argument, and three optional arguments that provide context and can be used 
-  for returning scaled representations of a value. An example of this is 
-  representing time values in a scale such as the time conductor scale. There 
-  are multiple ways of representing a point in time, and by providing a minimum
-  scale value, maximum scale value, and a count, it's possible to provide more
-  useful representations of time given the provided limitations.  
-    * `value`: The raw telemetry value in its native type.
-    * `minValue`: An __optional__ argument specifying the minimum displayed 
-      value.
-    * `maxValue`: An __optional__ argument specifying the maximum displayed 
-      value.
-    * `count`: An __optional__ argument specifying the number of displayed 
-      values.
-* `parse`: A `function` that takes a `string` representation of a telemetry 
-  value, and returns the value in its native type. **Note** parse might receive an already-parsed value.  This function should be idempotent.
-* `validate`: A `function` that takes a `string` representation of a telemetry 
-  value, and returns a `boolean` value indicating whether the provided string
-  can be parsed.
+```ts
+interface Formatter {
+    key: string; // A string that uniquely identifies this formatter.
+
+    format: (
+        value: any, // The raw telemetry value in its native type.

+        maxValue?: number, // An optional argument specifying the maximum displayed value.
+        count?: number // An optional argument specifying the number of displayed values.
+    ) => string; // Returns a human-readable string representation of the provided value.
+
+    parse: (
+        value: string | any // A string representation of a telemetry value or an already-parsed value.
+    ) => any; // Returns the value in its native type. This function should be idempotent.
+
+    validate: (value: string) => boolean; // Takes a string representation of a telemetry value and returns a boolean indicating whether the provided string can be parsed.
+}
+```
+
+##### Built-in Formats
+
+Open MCT on its own defines a handful of built-in formats:
+
+###### **Number Format (default):** 
+
+Applied to data with `format: 'number'`
+```js
+valueMetadata = {
+    format: 'number'
+    // ...
+};
+```
+
+```ts
+interface NumberFormatter extends Formatter {
+    parse: (x: any) => number;
+    format: (x: number) => string;
+    validate: (value: any) => boolean;
+}
+```
+###### **String Format**:
+
+Applied to data with `format: 'string'`
+```js
+valueMetadata = {
+    format: 'string'
+    // ...
+};
+```
+```ts
+interface StringFormatter extends Formatter {
+    parse: (value: any) => string;
+    format: (value: string) => string;
+    validate: (value: any) => boolean;
+}
+```
+
+###### **Enum Format**:
+Applied to data with `format: 'enum'`
+```js
+valueMetadata = {
+    format: 'enum',
+    enumerations: [
+    {
+        value: 1,
+        string: 'APPLE'
+    }, 
+    {
+        value: 2,
+        string: 'PEAR',
+    },
+    {
+        value: 3,
+        string: 'ORANGE'
+    }]
+    // ...
+};
+```
+
+Creates a two-way mapping between enum string and value to be used in the `parse` and `format` methods.
+Ex:
+- `formatter.parse('APPLE') === 1;`
+- `formatter.format(1) === 'APPLE';`
+

 #### Clock Offsets
 
-When a clock is active, the time bounds of the application will be updated 
-automatically each time the clock "ticks". The bounds are calculated based on 
-the current value provided by the active clock (via its `tick` event, or its 
-`currentValue()` method). 
+When in Real-time [mode](#time-modes), the time bounds of the application will be updated automatically each time the 
+clock "ticks". The bounds are calculated based on the current value provided by 
+the active clock (via its `tick` event, or its `currentValue()` method).
 
 Unlike bounds, which represent absolute time values, clock offsets represent
 relative time spans. Offsets are defined as an object with two properties:
 
-* `start`: A `number` that must be < 0 and which is used to calculate the start 
+- `start`: A `number` that must be < 0 and which is used to calculate the start
 bounds on each clock tick. The start offset will be calculated relative to the
 value provided by a clock's tick callback, or its `currentValue()` function.
-* `end`: A `number` that must be >= 0 and which is used to calculate the end 
+- `end`: A `number` that must be >= 0 and which is used to calculate the end
 bounds on each clock tick.

+The `setClockOffsets` function can be used to get or set clock offsets. For example,

-openmct.time.clockOffsets({

+
+### Time Modes
+
+There are two time modes in Open MCT, "Fixed" and "Real-time". In Real-time mode the 
+time bounds of the application will be updated automatically each time the clock "ticks".
+The bounds are calculated based on the current value provided by the active clock. In 
+Fixed mode, the time bounds are set for a specified time range. When Open MCT is first
+initialized, it will be in Real-time mode.
+
+The `setMode` method can be used to set the current time mode. It accepts a mode argument,
+`'realtime'` or `'fixed'` and it also accepts an optional [offsets](#clock-offsets)/[bounds](#time-bounds) argument dependent
+on the current mode.
+
+``` javascript
+openmct.time.setMode('fixed');
+openmct.time.setMode('fixed', bounds); // with optional bounds
+```
+
+or
+
+``` javascript
+openmct.time.setMode('realtime');
+openmct.time.setMode('realtime', offsets); // with optional offsets
+```
+
+The `getMode` method will return the current time mode, either `'realtime'` or `'fixed'`.
+
+``` javascript
+openmct.time.getMode();
+```
+
+#### Time Mode Helper Methods
+
+There are two methods available to determine the current time mode in Open MCT programmatically,
+`isRealTime` and `isFixed`. Each one will return a boolean value based on the current mode.
+
+``` javascript
+if (openmct.time.isRealTime()) {

-### 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 tests which exercise plugins, API, and utility classes. 
-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.
-
-#### Guidelines
-* 100% statement coverage is achievable and desirable.
-* Do blackbox testing. Test external behaviors, not internal details. Write tests that describe what your plugin is supposed to do. How it does this doesn't matter, so don't test it.
-* 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 you’re 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.
-* If writing unit tests for legacy Angular code be sure to follow [best practices in order to avoid memory leaks](https://www.thecodecampus.de/blog/avoid-memory-leaks-angularjs-unit-tests/).

 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.

+
+## 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 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.js` 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 are run in the '@stable' configuration and focus on chrome/ubuntu at a single resolution. This coverage is published to codecov with `npm run cov:e2e:stable:publish`.
+1. The rest of our coverage only appears when run against `@unstable` tests, 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
+There are two ways to know if a test on your branch is historically flaky: 
+1. `deploysentinel`'s PR comment bot to give an accurate and historical view of e2e flakiness. Check your PR for a view of the test failures and flakes (with link to the failing test). Note: only a 7 day window of flake is available.
+2. (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.
+
+#### Busting Cache
+In certain circumstances, the CircleCI cache can become stale. In order to bust the cache, we've implemented a runtime boolean parameter in Circle CI creatively name BUST_CACHE. To execute:
+1. Navigate to the branch in Circle CI believed to have stale cache.
+1. Click on the 'Trigger Pipeline' button.
+1. Add Parameter -> Parameter Type = boolean , Name = BUST_CACHE ,Value = true
+1. Click 'Trigger Pipeline'
+
+#### 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>
+```

+
+## 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 three 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.**
+
+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
+npx playwright test --config=e2e/playwright-ci.config.js --project=chrome --grep @snapshot
+```
+
+### 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.
+
+MacOS
+
+```
+npm run test:e2e:updatesnapshots
+```
+
+Linux/CI
+
+```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
+```
+
+## Performance Testing
+
+The open source performance tests function in three ways which match their naming and folder structure:
+
+`./e2e/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.
+`./e2e/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.
+`./e2e/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.
+
+## Test Architecture and CI
+
+### Architecture
+
+### File Structure
+
+Our file structure follows the type of type of testing being excercised 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/`             | Visual tests.|
+|`./tests/visual/component/`             | Visual 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.config.js` | Used to run the visual 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|
+|:-:|-|
+|`@ipad` | 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).|
+|`@gds` | Denotes a GDS Test Case used in the VIPER Mission.|
+|`@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.|
+|`@unstable` | A new test or test which is known to be flaky.|
+|`@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.|
+
+### Continuous Integration
+
+The cheapest time to catch a bug is pre-merge. Unfortuantely, 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
+
+- Stable e2e tests against ubuntu and chrome
+- Performance tests against ubuntu and chrome
+- e2e tests are linted
+- Visual 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 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 CircelCI 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.
+
+#### Test Promotion
+
+In order to maintain fast and reliable feedback, tests go through a promotion process. All new test cases or test suites must be labeled with the `@unstable` annotation. The Open MCT dev team runs these unstable tests in our private repos to ensure they work downstream and are reliable.
+
+- To run the stable tests, use the `npm run test:e2e:stable` command.
+- To run the new and flaky tests, use the `npm run test:e2e:unstable` command.
+
+A testcase and testsuite are to be unmarked as @unstable when:
+
+1. They run as part of "full" run 5 times without failure.
+2. They've been by a Open MCT Developer 5 times in the closed source repo without failure.
+
+### 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 the Mission-need to support iPad. To run our iPad suite, please see our `playwright-*.config.js` with the 'iPad' project.
+
+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) and so this will likely turn into a separate suite.
+
+#### **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
+  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.
+
+##### 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.
+
+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/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})`)
+    ```
+
+#### 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. To do this, use the `overrideClock` fixture as such:
+
+```js
+const { test, expect } = require('../../pluginFixtures.js');
+
+test.describe('foo test suite', () => {

+
+- 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.
+
+### 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?
+
+### 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`
