From 15 hours to 15 seconds: reducing a crushing build time

  • Bad Practice #1: We favoured integration tests over unit tests.
  • Bad Practice #2: We had many, many features that were relatively unimportant.
  • Bad Practice #3: Our integration tests were actually acceptance tests.
  • Bonus tip:┬árun the build entirely on the tmpfs in-memory file system.
