- 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 The Plan 12

- 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 Conclusions 17
