17. Test Driven DEVELOPMENT
18. TEST DRIVEN DEVELOPMENT - what ‣Extreme Programming (XP) ‣Kent Beck, 2003 ‣Tests first
19. TEST DRIVEN DEVELOPMENT - how Red - Green - Refactor Image src: https://giphy.com/gifs/peteandpete-season-3-the-adventures-of-pete-and-3o7Z4tNIWOQWTlfGN2
20. TDD CYCLE ‣ ❌ Write a test. ‣ ❌ That test fails - obviously ‣ ❌ Write code that makes the test pass ‣ ✅ Test pass! ‣ # Refactor Rinse and repeat! Image src: https://giphy.com/gifs/girl-yeah-wash-JS88XIgg7laNO
21. LET'S WRITE SOME ✨ tests
22. DOG TRAINING SIMULATOR TASK Program to show others how to train a specific behavior to a dog.
23. DOG TRAINING SIMULATOR USER STORY I have a dog and I want to teach this dog the behavior "Touch", using positive reinforcement as a technique.
24. DOG TRAINING SIMULATOR INITIAL SITUATION aka: Requirements ‣no past no conditioning ‣rewarding, neutral and punishing consequences ‣visible reactions to consequences
25. DOG TRAINING SIMULATOR MY TRAINING WILL BE SUCCESSFUL WHEN... aka: Acceptance Criteria ‣When I say "Touch" ‣and hold two fingers so my dog can access them, ‣my dog comes immediately and with joyful body language to me ‣and presses its nose the two fingers shortly
26. LET'S THINK ABOUT THIS Image src: https://giphy.com/gifs/dog-computer-ChpOyeacGmpQk

96. SUMMARY
97. WHAT - imho - TDD IS ABOUT ‣TDD is not a strategy for tests, it's a strategy for design. ‣It helps to stay focused and keep things simple. ‣It makes changes easier and refactoring safer. ‣You can work in quick iterations and get in a very motivating feedback loop.
98. GET INTO TDD HOW TO GET STARTED ‣ start with small problems ‣ be open and creative Image src: https://giphy.com/gifs/cute-aww-eyebleach-xFnAObsU5nMrUUC3HX
99. GET INTO TDD HOW TO GET STARTED ‣ start with small problems ‣ be open and creative ‣ don't be dogmatic Image src: https://www.youtube.com/watch?v=dQw4w9WgXcQ
