6. Stories from Real World

7. We can‘t run integration tests in parallel.

8. Running all of our tests takes ages.

9. Our integration tests are fragile.

10. Producing a bugfix release is hard work.

11. Time For A Plan

12. 〉 Git-Pushes go to feature/bugfix branches
〉 Every Git-Push triggers a test
〉 Tests run in prod-like environments
〉 Tests run in isolated/dedicated environments
〉 Automate (almost) everything
〉 Increase & maintain (infra) test coverage

16. Conclusions

17. 〉 Don‘t underestimate the effort for CI/CD preparation
〉 Isolated integration testing at ludicrous speed
〉 Infrastructure as Code improves documentation
〉 Similarity to production leads to faster bugfixing
〉 Parallel testing increases work efficiency
