 ## 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).

 ### 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.

 #### 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.

 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')`

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');
+```

 ### 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.
