-  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

+
+##### 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;
+}

+
+The `setMode` method can be used to set the current time mode. It accepts a mode argument,

+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()) {

+can be used to manage user information and roles.
+
+### Example
+
+Open MCT provides an example [user](example/exampleUser/exampleUserCreator.js) and [user provider](example/exampleUser/ExampleUserProvider.js) which
+can be used as a starting point for creating a custom user provider.
+
+## 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.

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.

+## 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.)

 ## 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`.

 ## Code Coverage
 
-* 100% statement coverage is achievable and desirable.
+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.
 
-Codecov.io will combine each of the above commands with [Codecov.io Flags](https://docs.codecov.com/docs/flags). Effectively, this allows us to combine multiple reports which are run at various stages of our CI Pipeline or run as part of a parallel process.
+Line Code Coverage is generated by our unit tests and e2e tests, then combined by ([Codecov.io Flags](https://docs.codecov.com/docs/flags)), and finally reported in GitHub PRs by Codecov.io's PR Bot. This workflow gives a comprehensive (if flawed) view of line coverage.
+
+### Karma-istanbul
+
+Line coverage is generated by our `karma-coverage-istanbul-reporter` package as defined in our `karma.conf.js` file:
+
+```js
+    coverageIstanbulReporter: {
+      fixWebpackSourcePaths: true,
+      skipFilesWithNoCoverage: true,
+      dir: 'coverage/unit', //Sets coverage file to be consumed by codecov.io
+      reports: ['lcovonly']
+    },
+```
+
+Once the file is generated, it can be published to codecov with
+
+```json
+    "cov:unit:publish": "codecov --disable=gcov -f ./coverage/unit/lcov.info -F unit",
+```
+
+### e2e
+The e2e line coverage is a bit more complex than the karma implementation. This is the general sequence of events:
+
+1. Each e2e suite will start webpack with the ```npm run start:coverage``` command with config `webpack.coverage.mjs` and the `babel-plugin-istanbul` plugin to generate code coverage during e2e test execution using our custom [baseFixture](./baseFixtures.js). 
+1. During testcase execution, each e2e shard will generate its piece of the larger coverage suite. **This coverage file is not merged**. The raw coverage file is stored in a `.nyc_report` directory.
+1. [nyc](https://github.com/istanbuljs/nyc) converts this directory into a `lcov` file with the following command `npm run cov:e2e:report`
+1. Most of the tests focus on chrome/ubuntu at a single resolution. This coverage is published to codecov with `npm run cov:e2e:ci:publish`.
+1. The rest of our coverage only appears when run against persistent datastore (couchdb), non-ubuntu machines, and non-chrome browsers with the `npm run cov:e2e:full:publish` flag. Since this happens about once a day, we have leveraged codecov.io's carryforward flag to report on lines covered outside of each commit on an individual PR.
 
-This e2e coverage is combined with our unit test report to give a comprehensive (if flawed) view of line coverage.
 
 ### Limitations in our code coverage reporting
+Our code coverage implementation has some known limitations:
+- [Variability](https://github.com/nasa/openmct/issues/5811)
+- [Accuracy](https://github.com/nasa/openmct/issues/7015)
+- [Vue instrumentation gaps](https://github.com/nasa/openmct/issues/4973)

+## Troubleshooting CI
+The following is an evolving guide to troubleshoot CI and PR issues.
+
+### Github Checks failing
+There are a few reasons that your GitHub PR could be failing beyond simple failed tests.
+* Required Checks. We're leveraging required checks in GitHub so that we can quickly and precisely control what becomes and informational failure vs a hard requirement. The only way to determine the difference between a required vs information check is check for the `(Required)` emblem next to the step details in GitHub Checks.
+* Not all required checks are run per commit. You may need to manually trigger addition GitHub checks with a `pr:<label>` label added to your PR.
+
+### Flaky tests
+
+(CircleCI's test insights feature)[https://circleci.com/blog/introducing-test-insights-with-flaky-test-detection/] collects historical data about the individual test results for both unit and e2e tests. Note: only a 14 day window of flake is available.
+
+### Local=Pass and CI=Fail
+Although rare, it is possible that your test can pass locally but fail in CI.
+
+### Reset your workspace
+It's possible that you're running with dependencies or a local environment which is out of sync with the branch you're working on. Make sure to execute the following:
+
+```sh
+nvm use
+npm run clean
+npm install
+```
+
+#### Run tests in the same container as CI
+
+In extreme cases, tests can fail due to the constraints of running within a container. To execute tests in exactly the same way as run in CircleCI. 
+
+```sh
+// Replace {X.X.X} with the current Playwright version 
+// from our package.json or circleCI configuration file
+docker run --rm --network host --cpus="2" -v $(pwd):/work/ -w /work/ -it mcr.microsoft.com/playwright:v{X.X.X}-focal /bin/bash
+npm install
+```
+
+At this point, you're running inside the same container and with 2 cpu cores. You can specify the unit tests:
+```sh
+npm run test
+```
+or e2e tests:
+
+```sh
+npx playwright test --config=e2e/playwright-ci.config.js --project=chrome --grep <the testcase name>

+# 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.

 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.**

For more information, please see the official [Percy documentation](https://docs.percy.io/docs/visual-testing-basics).
 
-### (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.
 
-Read more about [Playwright Snapshots](https://playwright.dev/docs/test-snapshots)
+#### 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`
+`tests/performance` - The tests at the root of this folder path detect functional changes which are mostly apparent with large performance regressions like [this](https://github.com/nasa/openmct/issues/6879). These tests run against openmct webpack in `production-mode` with the `npm run test:perf:localhost` script.
+`tests/performance/contract/` -  These tests serve as [contracts](https://martinfowler.com/bliki/ContractTest.html) for the locator logic, functionality, and assumptions will work in our downstream, closed source test suites. These tests run against openmct webpack in `dev-mode` with the `npm run test:perf:contract` script.
+`tests/performance/memory/` -  These tests execute memory leak detection checks in various ways. This is expected to evolve as we move to the `memlab` project. These tests run against openmct webpack in `production-mode` with the `npm run test:perf:memory` script.
 
 These tests are expected to become blocking and gating with assertions as we extend the capabilities of Playwright.
 
+In addition to the explicit definition of performance tests, we also ensure that our test timeout timing is "tight" to catch performance regressions detectable by action timeouts. i.e. [Notebooks load much slower than they used to #6459](https://github.com/nasa/openmct/issues/6459)

-- How to make tests faster and more resilient

+#### Test as the User
 
-  ```javascript
+In general, strive to test only through the UI as a user would. As stated in the [Playwright Best Practices](https://playwright.dev/docs/best-practices#test-user-visible-behavior):
+
+> "Automated tests should verify that the application code works for the end users, and avoid relying on implementation details such as things which users will not typically use, see, or even know about such as the name of a function, whether something is an array, or the CSS class of some element. The end user will see or interact with what is rendered on the page, so your test should typically only see/interact with the same rendered output."
+
+By adhering to this principle, we can create tests that are both robust and reflective of actual user experiences.
+
+#### How to make tests robust to function in other contexts (VISTA, COUCHDB, YAMCS, VIPER, etc.)
+
+  1. Leverage the use of `appActions.js` methods such as `createDomainObjectWithDefaults()`. This ensures that your tests will create unique instances of objects for your test to interact with.
+  1. Do not assert on the order or structure of objects available unless you created them yourself. These tests may be used against a persistent datastore like couchdb with many objects in the tree.
+  1. Do not search for your created objects. Open MCT does not performance uniqueness checks so it's possible that your tests will break when run twice.
+  1. Avoid creating locator aliases. This likely means that you're compensating for a bad locator. Improve the application instead.
+  1. Leverage `await page.goto('./', { waitUntil: 'domcontentloaded' });` instead of `{ waitUntil: 'networkidle' }`. Tests run against deployments with websockets often have issues with the networkidle detection.
+  
+#### How to make tests faster and more resilient to application changes
+  1. Avoid app interaction when possible. The best way of doing this is to navigate directly by URL:
+
+  ```js
     // You can capture the CreatedObjectInfo returned from this appAction:
     const clock = await createDomainObjectWithDefaults(page, { type: 'Clock' });

-### How to write a great test (WIP)
+##### 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)
+      }); 
+    ```

+- 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.

-#### How to write a great visual test (TODO)
+#### How to Write a Great Visual Test
+
+1. **Look for the Unknown Unknowns**: Avoid asserting on specific differences in the visual diff. Visual tests are most effective for identifying unknown unknowns.
+
+2. **Get the App into Interesting States**: Prioritize getting Open MCT into unusual layouts or behaviors before capturing a visual snapshot. For instance, you could open a dropdown menu.
+
+3. **Expect the Unexpected**: Use functional expect statements only to verify assumptions about the state between steps. A great visual test doesn't fail during the test itself, but rather when changes are reviewed in Percy.io.
+
+4. **Control Variability**: Account for variations inherent in working with time-based telemetry and clocks.
+
+- Utilize `percyCSS` to ignore time-based elements. For more details, consult our [percyCSS file](./.percy.ci.yml).
+- Use Open MCT's fixed-time mode unless explicitly testing realtime clock
+- Employ the `createExampleTelemetryObject` appAction to source telemetry and specify a `name` to avoid autogenerated names.
+- Avoid creating objects with a time component like timers and clocks.
+- Utilize the playwright clock() API. See @clock Annotations for examples.
+
+5. **Hide the Tree and Inspector**: Generally, your test will not require comparisons involving the tree and inspector. These aspects are covered in component-specific tests (explained below). To exclude them from the comparison by default, navigate to the root of the main view with the tree and inspector hidden:
+    - `await page.goto('./#/browse/mine?hideTree=true&hideInspector=true')`
+
+6. **Component-Specific Tests**: If you wish to focus on a particular component, use the `/visual-a11y/component/` folder and limit the scope of the comparison to that component. For instance:
+
+    ```js
+    await percySnapshot(page, `Tree Pane w/ single level expanded (theme: ${theme})`, {
+        scope: treePane
+    });
+    ```
+
+    - Note: The `scope` variable can be any valid CSS selector.
+
+7. **Write many `percySnapshot` commands in a single test**: In line with our approach to longer functional tests, we recommend that many test percySnapshots are taken in a single test. For instance:
+
+    ```js
+    //<Some interesting state>
+    await percySnapshot(page, `Before object expanded (theme: ${theme})`);
+    //<Click on object>
+    await percySnapshot(page, `object expanded (theme: ${theme})`);
+    //Select from object
+    await percySnapshot(page, `object selected (theme: ${theme})`)
+    ```
+8. **Use `networkidle` to wait for network requests to complete**: This is necessary to ensure that all network requests have completed before taking a snapshot. This ensures that icons are loaded and other assets are available. https://github.com/nasa/openmct/issues/7549

+### Tips & Tricks
 
 The following contains a list of tips and tricks which don't exactly fit into a FAQ or Best Practices doc.
 
+- (Advanced) Overriding the Browser's Clock
+It is possible to override the browser's clock in order to control time-based elements. Since this can cause unwanted behavior -- i.e. Tree not rendering -- only use this sparingly. Use the `page.clock()` API as such:
+
+```js
+import { test, expect } from '../../pluginFixtures.js';
+
+test.describe('foo test suite @clock', () => {
+  test.beforeEach(async ({ page }) => {
+    //Set clock time
+    await page.clock.install({ time: MISSION_TIME });
+    await page.clock.resume();
+    //Navigate to page with new clock
+    await page.goto('./', { waitUntil: 'domcontentloaded' });
+  });
+
+  test('bar here', async ({ page }) => {
+    /// ...
+  });
+  ```
+
 - Working with multiple pages
-There are instances where multiple browser pages will 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.
+
+- 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');
