 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/).

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).

 ## Test Architecture and CI
 
 ### Architecture (TODO)

 ### 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.
 
- - `./helper` - contains helper functions or scripts which are leveraged directly within the testsuites. i.e. non-default plugin scripts injected into DOM
- - `./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.

 We leverage Github Actions / Workflows to execute tests as it gives us the ability to run against multiple operating systems with greater control over git event triggers (i.e. Run on a PR Comment event).
 
 Our CI environment consists of 3 main modes of operation:
 
 #### 1. Per-Commit Testing

 - e2e tests are linted
 
 #### 2. Per-Merge Testing

 - 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.

+- `playwright-chrome`
+  - The stable channel of Chrome from the official chrome channels. This is always 2 versions behind chromium.

 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```
