 Visual Testing is an essential part of our e2e strategy as it ensures that the application _appears_ correctly to a user while it compliments the functional e2e suite. It would be impractical to make thousands of assertions functional assertions on the look and feel of the application.

 To make this possible, we're leveraging a 3rd party service, [Percy](https://percy.io/). 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_.

For more information, please see the official [Percy documentation](https://docs.percy.io/docs/visual-testing-basics)
 
 ### (Advanced) Snapshot Testing
 
 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.
 
-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).

 ### 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/example/` - tests which specifically verify the example plugins
- - `./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
- - `./tests/framework/` - tests which verify that our testframework functionality and assumptions will continue to work based on further refactoring or playwright version changes
- - `./tests/performance/` - performance tests
- - `./tests/visual/` - Visual tests
- - `./appActions.js` - Contains common fixtures which can be leveraged by testcase authors to quickly move through the application when writing new tests.
- - `./baseFixture.js` - Contains base fixtures which only extend default `@playwright/test` functionality. The goal is to remove these fixtures as native Playwright APIs improve.

 Our CI environment consists of 3 main modes of operation:

 - Performance tests against ubuntu and chrome
 - e2e tests are linted
 
 #### 2. Per-Merge Testing

 - Full suite against all browsers/projects. Triggered with Github Label Event 'pr:e2e'
 - Visual Tests. Triggered with Github Label Event 'pr:visual'

 - Full e2e suite against ubuntu and chrome
 - Performance tests against ubuntu and chrome

 - Visual Test baseline generation.

 In order to provide fast feedback in the Per-Commit context, we try to keep total test feedback at 5 minutes or less. That is to say, A developer should have a pass/fail result in under 5 minutes.

+  - A beta version of Chromium from official chromium channels. As close to the bleeding edge as we can get.
+- `playwright-chromium`
+  - A stable version of Chromium from the official chromium channels. This is always at least 1 version ahead of desktop chrome.
+- `playwright-chrome`
+  - The stable channel of Chrome from the official chrome channels. This is always 2 versions behind chromium.

 At this point, the nyc linecov report can be published to [codecov.io](https://about.codecov.io/) with the following command:
 
-```npm run cov:e2e:stable:publish``` for the stable suite running in ubuntu. 
-or 
+```npm run cov:e2e:stable:publish``` for the stable suite running in ubuntu.
+or
 ```npm run cov:e2e:full:publish``` for the full suite running against all available platforms.
 
 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.
 
 This e2e coverage is combined with our unit test report to give a comprehensive (if flawed) view of line coverage.
