+### Example

+
+## Visibility-Based Rendering in View Providers
+
+To enhance performance and resource efficiency in OpenMCT, a visibility-based rendering feature has been added. This feature is designed to defer the execution of rendering logic for views that are not currently visible. It ensures that views are only updated when they are in the viewport, similar to how modern browsers handle rendering of inactive tabs but optimized for the OpenMCT tabbed display. It also works when views are scrolled outside the viewport (e.g., in a Display Layout).
+
+### Overview
+
+The show function is responsible for the rendering of a view. An [Intersection Observer](https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API) is used internally to determine whether the view is visible. This observer drives the visibility-based rendering feature, accessed via the `renderWhenVisible` function provided in the `viewOptions` parameter.
+
+### Implementing Visibility-Based Rendering
+
+The `renderWhenVisible` function is passed to the show function as part of the `viewOptions` object. This function can be used for all rendering logic that would otherwise be executed within a `requestAnimationFrame` call. When called, `renderWhenVisible` will either execute the provided function immediately (via `requestAnimationFrame`) if the view is currently visible, or defer its execution until the view becomes visible.
+
+Additionally, `renderWhenVisible` returns a boolean value indicating whether the provided function was executed immediately (`true`) or deferred (`false`).
+
+Monitoring of visibility begins after the first call to `renderWhenVisible` is made.
+
+Here’s the signature for the show function:
+
+`show(element, isEditing, viewOptions)`
+
+- `element` (HTMLElement) - The DOM element where the view should be rendered.
+- `isEditing` (boolean) - Indicates whether the view is in editing mode.
+- `viewOptions` (Object) - An object with configuration options for the view, including:
+  - `renderWhenVisible` (Function) - This function wraps the `requestAnimationFrame` and only triggers the provided render logic when the view is visible in the viewport.
+
+### Example
+
+An OpenMCT view provider might implement the show function as follows:
+
+```js
+// Define your view provider
+const myViewProvider = {
+  // ... other properties and methods ...
+  show: function (element, isEditing, viewOptions) {
+    // Callback for rendering view content
+    const renderCallback = () => {
+      // Your view rendering logic goes here
+    };
+    
+    // Use the renderWhenVisible function to ensure rendering only happens when view is visible
+    const wasRenderedImmediately = viewOptions.renderWhenVisible(renderCallback);
+
+    // Optionally handle the immediate rendering return value
+    if (wasRenderedImmediately) {
+      console.debug('🪞 Rendering triggered immediately as the view is visible.');
+    } else {
+      console.debug('🛑 Rendering has been deferred until the view becomes visible.');
+    }
+  }
+};
+```
+
+Note that `renderWhenVisible` defers rendering while the view is not visible and caters to the latest execution call. This provides responsiveness for dynamic content while ensuring performance optimizations.
+
+Ensure your view logic is prepared to handle potentially multiple deferrals if using this API, as only the last call to renderWhenVisible will be queued for execution upon the view becoming visible.

 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.

+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/).
 
-`npm run test:e2e:stable`
+#### How to Run Tests
 
-To run the visual test suite:
+- **e2e Tests**: These tests are run on every commit. To run the tests locally, use:
 
-`npm run test:e2e:visual`
+  ```sh
+  npm run test:e2e:ci
+  ```
 
-To run the performance tests:
+- **Visual Tests**: For running the visual test suite, use:
 
-`npm run test:perf`
+  ```sh
+  npm run test:e2e:visual
+  ```
 
-The test suite is configured to all tests located in `e2e/tests/` ending in `*.e2e.spec.js`. For more about the e2e test suite, please see the [README](./e2e/README.md)
+- **Performance Tests**: To initiate the performance tests, enter:
+
+  ```sh
+  npm run test:perf
+  ```
+
+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).
 
 ### Security Tests
+
 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).

-# Glossary
+## Glossary
 
 Certain terms are used throughout Open MCT 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.
-
-* _plugin_: A plugin is a removable, reusable grouping of software elements.
-  The application is composed of plugins.
-* _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. 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 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.)
-* _namespace_: A name used to identify a persistence store. A running open MCT 
-application could potentially use multiple persistence stores, with the

 ## 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`.

+- 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.

+# 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.

+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".

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.

+## 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:
 
-`./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.
+`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 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)

 #### 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.

 - 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.

 - 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.
