Summary:
Currently we have a single giant file with all tests, and a giant snapshot. This is both slow, and hard to work with and iterate on.
In this PR I will refactor our test setup.
- [x] Split it up into multiple files (gets the test running from 45s to 27s)
- [x] Run Prettier on test files
- [x] Split tests further for better performance
- [x] Make it possible to run one test file
- [x] Fix the issue with double test re-runs in watch mode on changes in the test file
- [x] Refactor error handling
- [x] Run Prettier on fixtures
- [x] Add a fast mode with `yarn test-react-fast <Filename>`
- [x] Fix double reruns on failure
Potential followups:
- [x] Figure out why test interruption broke (need https://github.com/facebook/jest/issues/6599 and https://github.com/facebook/jest/issues/6598 fixed)
- [x] Revisit weird things like `this['React']` assignment with a funny comment in every test
