Support binary websockets

* feat(IndicatorAPI): accept Vue components

- Adds a new property to Indicators, `component`, which is a synchronous or asynchronous Vue component.
- Adds `wrapHtmlElement` utility function to create anonymous Vue components out of `HTMLElement`s (for backwards compatibility)
- Refactors StatusIndicators.vue to use dynamic components, allowing us to dynamically render indicators (and keep it all within Vue's ecosystem).

* refactor(indicators): use dynamic Vue components instead of `mount()`

- Refactors some indicators to use Vue components directly as async components

* refactor: use Vue reactivity for timestamps in clock indicator

* fix(test): fix unit tests and remove some console logs

* test(e2e): stabilize ladSet e2e test

* test: mix in some Vue indicators in indicatorSpec

* refactor: cleanup variable names

* docs: update IndicatorAPI docs

* fix(e2e): wait for async status bar components to load before snapshot

* a11y(e2e): add aria-labels and wait for status bar to load

* test(e2e): add exact: true

* fix: initializing indicators

* fix(typo): uhhh.. how did that get there? O_o

* fix: use synchronous components for default indicators

* test: clean up, remove unnecessary `nextTick()`s

* test: remove more `nextTick()`s

* refactor: lint:fix

* fix: `on` -> `off`

* test(e2e): stabilize tabs test

* test(e2e): attempt to stabilize limit lines tests with `toHaveCount()` assertion

+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.
+        minValue?: number, // An optional argument specifying the minimum displayed value.
+        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';`
+
+```ts
+interface EnumFormatter extends Formatter {
+    parse: (value: string) => string;
+    format: (value: number) => string;
+    validate: (value: any) => boolean;
+}

+## 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.

-### 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.

+# 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 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.
+
+#### 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.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
+
+(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>
+```

-### (Advanced) Snapshot Testing
+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. 
 
-Snapshot testing is very similar to visual testing but allows us to be more precise in detecting change without relying on a 3rd party service. Unfortuantely, this precision requires advanced test setup and teardown and so we're using this pattern as a last resort.
+### Advanced: Snapshot Testing (Not Recommended)
 
-To give an example, if a _single_ visual test assertion for an Overlay plot is run through multiple DOM rendering engines at various viewports to see how the Plot looks. If that same test were run as a snapshot test, it could only be executed against a single browser, on a single platform (ubuntu docker container).
+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.

+
+## 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 mostly as a contract for the locator logic, functionality, and assumptions will work in our downstream, closed source test suites.
+The open source performance tests function in three ways which match their naming and folder structure:
 
-They're found under `./e2e/tests/performance` and are to be executed with the following npm script:
-
-`npm run test:perf`
+`./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.
 
+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)

 ### 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.

-- `./test-data` - contains test data which is leveraged or generated in the functional, performance, or visual test suites. i.e. localStorage data
-- `./tests/functional` - the bulk of the tests are contained within this folder to verify the functionality of open mct

-- `./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

+#### Test as the User
 
-### How to write a great test (TODO)
+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):
 
-#### How to write a great visual test (TODO)
+> "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-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})`)
+    ```
+
+#### 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.
 
-### Tips & Tricks (TODO)
+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
+import { test, expect } from '../../pluginFixtures.js';
+
+test.describe('foo test suite', () => {
+  
+  // All subsequent tests in this suite will override the clock
+  test.use({
+    clockOptions: {
+      now: 1732413600000, // A timestamp given as milliseconds since the epoch
+      shouldAdvanceTime: true // Should the clock tick?
+    }
+  });
+
+  test('bar test', async ({ page }) => {
+    // ...
+  });
+});
+  ```
+  More info and options for `overrideClock` can be found in [baseFixtures.js](baseFixtures.js)
+
 - Working with multiple pages
-There are instances where multiple browser pages will need to be opened to verify multi-page or multi-tab application behavior.
+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.

+
+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.

-- Why is my test failing on CI and not locally?
-- How can I view the failing tests on 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.

+#### **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`
