How to speed up Cypress tests

In general

1. Discover how slow your tests are to start begin with
2. Don’t speed up your tests if you don’t need too
3. Work on the tests that take the longest. List all tests that take over x seconds/minutes and work on those
4. A small improvement can give you big gains in the long run
5. Only test what you need too and when you need too

Cypress

1. Group similar tests together into a single test
2. Separate tests that don’t need state, change of state or require a fixed state
3. Pay attention on the before and beforeEach hooks
4. Disable the video and screenshot creation on automatic builds
5. Enable video and screenshot creation on manual/nightly builds
