Sometimes it is not clear for everybody how unit tests relates to e2e-test. This cheatsheet, I created, describes in one page:

  1. The different definitions
  2. Different structures of the tests
  3. The importance of unit tests
  4. The importance of e2e tests
  5. External versus internal quality
  6. E2E and unit tests living next to each other

Feel free to download and use it in your project if you feel there is a confusion of tongues between unit and e2e tests.
