+Fixed mode, the time bounds are set for a specified time range. When Open MCT is first
+initialized, it will be in Real-time mode.
+
+The `setMode` method can be used to set the current time mode. It accepts a mode argument,
+`'realtime'` or `'fixed'` and it also accepts an optional [offsets](#clock-offsets)/[bounds](#time-bounds) argument dependent
+on the current mode.
+
+``` javascript
+openmct.time.setMode('fixed');

+```
+
+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()) {

 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.

 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
+### Advanced: Snapshot Testing (Not Recommended)
 
-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.
+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.
 
-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).
+#### 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.

+#### 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
+  1. Avoid app interaction when possible. The best way of doing this is to navigate directly by URL:

-#### How to write a great visual test
+ #### How to Write a Great Visual Test
 
- - Generally speaking, you should avoid being "specific" in what you hope to find in the diff. Visual tests are best suited for finding unknown unknowns.
- - These should only use functional expect statements to verify assumptions about the state
-in a test and not for functional verification of correctness. Visual tests are not supposed
-to "fail" on assertions. Instead, they should be used to detect changes between builds or branches.
- - A great visual test controls for the variation inherent to working with time-based telemetry and clocks. We do our best to remove this variation by using `percyCSS` to ignore all possible time-based components. For more, please see our [percyCSS file](./.percy.ci.yml).
- - Additionally, you should try the following:
-   - Use fixed-time mode of Open MCT
-   - Use the `createExampleTelemetryObject` appAction to source telemetry
-   - When using the `createDomainObjectWithDefaults` appAction, make sure to specify a `name` which is explicit to avoid the autogenerated name
- - Very likely, your test will not need to compare changes on the tree. Keep it out of the comparison with the following
-   - `await page.goto('./#/browse/mine')` will go to the root of the main view with the tree collapsed.
- - If you only want to compare changes on a specific component, use the /visual/component/ folder and limit the scope of the comparison to the object like so:
-   - ```
-      await percySnapshot(page, `Tree Pane w/ single level expanded (theme: ${theme})`, {
-            scope: treePane
-        });
+1. **Look for the Unknown Unknowns**: Avoid asserting on specific differences in the visual diff. Visual tests are most effective for identifying unknown unknowns.
+
+2. **Get the App into Interesting States**: Prioritize getting Open MCT into unusual layouts or behaviors before capturing a visual snapshot. For instance, you could open a dropdown menu.
+
+3. **Expect the Unexpected**: Use functional expect statements only to verify assumptions about the state between steps. A great visual test doesn't fail during the test itself, but rather when changes are reviewed in Percy.io.
+
+4. **Control Variability**: Account for variations inherent in working with time-based telemetry and clocks.
+  - Utilize `percyCSS` to ignore time-based elements. For more details, consult our [percyCSS file](./.percy.ci.yml).
+  - Use Open MCT's fixed-time mode unless explicitly testing realtime clock
+  - Employ the `createExampleTelemetryObject` appAction to source telemetry and specify a `name` to avoid autogenerated names.
+
+5. **Hide the Tree and Inspector**: Generally, your test will not require comparisons involving the tree and inspector. These aspects are covered in component-specific tests (explained below). To exclude them from the comparison by default, navigate to the root of the main view with the tree and inspector hidden:
+    - `await page.goto('./#/browse/mine?hideTree=true&hideInspector=true')`
+
+6. **Component-Specific Tests**: If you wish to focus on a particular component, use the `/visual/component/` folder and limit the scope of the comparison to that component. For instance:
     ```js
- - The `scope` variable can be any valid css selector
+    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})`)

 The following contains a list of tips and tricks which don't exactly fit into a FAQ or Best Practices doc.
 
+- (Advanced) Overriding the Browser's Clock
+It is possible to override the browser's clock in order to control time-based elements. Since this can cause unwanted behavior (i.e. Tree not rendering), only use this sparingly. To do this, use the `overrideClock` fixture as such:
+
+```js
+const { test, expect } = require('../../pluginFixtures.js');
+
+test.describe('foo test suite', () => {
+  
+  // 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.
