+# e2e testing
+
+This document captures information specific to the e2e testing of Open MCT. For general information about testing, please see [the Open MCT README](https://github.com/nasa/openmct/blob/master/README.md#tests).
+
+## Overview
+
+This document is designed to capture on the What, Why, and How's of writing and running e2e tests in Open MCT.
+
+### About e2e testing
+
+e2e testing is an industry-standard approach to automating the testing of web-based UIs such as Open MCT. Broadly speaking, e2e tests differentiate themselves from unit tests by preferring replication of real user interactions over execution of raw JavaScript functions.
+
+Historically, the abstraction necessary to replicate real user behavior meant that:
+
+- e2e tests were "expensive" due to how much code each test executed. The closer a test replicates the user, the more code is needed run during test execution. Unit tests could run smaller units of code more effeciently.
+- e2e tests were flaky due to network conditions or the underlying protocols associated with testing a browser.
+- e2e frameworks relied on a browser communication standard which lacked the observability and controls necessary needed to reach the code paths possible with unit and integration tests.
+- e2e frameworks provided insufficient debug information on test failure
+
+However, as the web ecosystem has matured to the point where mission-critical UIs can be written for the web (Open MCT), the e2e testing tools have matured as well. There are now fewer "trade-offs" when choosing to write an e2e test over any other type of test.
+
+Modern e2e frameworks:
+
+- Bypass the surface layer of the web-application-under-test and use a raw debugging protocol to observe and control application and browser state.
+- These new browser-internal protocols enable near-instant, bi-directional communication between test code and the browser, speeding up test execution and making the tests as reliable as the application itself.
+- Provide test debug tooling which enables developers to pinpoint failure
+
+Furthermore, the abstraction necessary to run e2e tests as a user enables them to be extended to run within a variety of contexts. This matches the extensible design of Open MCT. 
+
+A single e2e test in Open MCT is extended to run:
+
+- Against a matrix of browser versions.
+- Against a matrix of OS platforms.
+- Against a local development version of Open MCT.
+- A version of Open MCT loaded as a dependency (VIPER, VISTA, etc)
+- Against a variety of data sources or telemetry endpoints.
+
+### Why Playwright?
+
+[Playwright](https://playwright.dev/) was chosen as our e2e framework because it solves a few VIPER Mission needs:
+1. First-class support for Automated Performance Testing
+2. Official Chrome, Chrome Canary, and iPad Capabilities
+3. Support for Browserless.io
+4. Ability to generate code coverage reports
+
+## Getting Started
+
+### Getting started with Playwright
+
+### Getting started with Open MCT's implementation of Playwright
+
+## Types of Testing
+
+### (TBD) Visual Testing
+
+- Visual tests leverage [Percy](https://percy.io/).
+- Visual tests should be written within the `./tests/visual` folder so that they can be ignored during git clones to avoid leaking credentials when executing percy cli
+
+#### (TBD) How to write a good visual test
+
+### (TBD) Snapshot Testing
+
+<https://playwright.dev/docs/test-snapshots>
+
+### (TBD) Mobile Testing
+
+### (TBD) Performance Testing
+
+### (FUTURE) Component Testing
+
+- Component testing is currrently possible in Playwright but not enabled on this project. For more, please see: <https://playwright.dev/docs/test-components>
+
+## Architecture, Test Design and Best Practices
+
+### (TBD) Architecture
+
+#### (TBD)  Continuous Integration
+
+- Test maturation
+- Difference between full and e2e-ci suites
+- Platforms
+
+### (TBD) Multi-browser and Multi-operating system
+
+- Where is it tested
+- What's supported
+
+### (TBD) Test Design
+
+- Re-usable tests for VISTA, VIPER, etc.
+
+#### Annotations
+
+- Annotations are a great way of organizing tests outside of a file structure.
+- Current list of annotations:
+  - `@ipad` - Mobile execution possible with Playwright's iPad support.
+  - `@gds` - Executes a GDS Test Case. Used to track in VIPER Mission.
+  - `@addInit` - Initializes the browser with an injected and artificial state. Useful for non-default plugins.
+  - `@localStorage` - Captures or generates session storage to manipulate browser state. Useful for excluding in tests which require a persistent backend (i.e. CouchDB).
+  - `@snapshot` - Uses Playwright's snapshot functionality to record a copy of the DOM for direct comparison. Must be run inside of a container.
+
+### (TBD) Best Practices
+
+### (TBD) Reporting
+
+### (TBD) Code Coverage
+
+Code coverage is collected during test execution and reported with [nyc](https://github.com/istanbuljs/nyc) and [codecov.io](https://about.codecov.io/)
+
+## Other
+
+### FAQ
+
+- How does this help NASA missions?
+- When should I write an e2e test instead of a unit test?
+- When should I write a functional vs visual test?
+- How is Open MCT extending default Playwright functionality?
+
+### Troubleshooting
+
+- Why is my test failing on CI and not locally?
+- How can I view the failing tests on CI?
