1. Treat yourself A TALE ABOUT DOG TRAINING AND TEST DRIVEN DEVELOPMENT
2. HI! !
3. I ! TESTING Image src: https://www.youtube.com/watch?v=dQw4w9WgXcQ

15. Test Driven DEVELOPMENT
16. TEST DRIVEN DEVELOPMENT Tests first
17. TEST DRIVEN DEVELOPMENT - how Red - Green - Refactor Image src: https://giphy.com/gifs/peteandpete-season-3-the-adventures-of-pete-and-3o7Z4tNIWOQWTlfGN2
18. 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
19. BUT WHY?

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 - no past no conditioning - rewarding, neutral and punishing consequences - visible reactions to consequences
25. DOG TRAINING SIMULATOR My training will be successful when... - I say "Touch" - and hold two fingers so my dog can access them, - my dog comes immediately and - with a joyful body language to me and - presses its nose at the two fingers shortly.
26. LET'S THINK ABOUT THIS
27. ✋ STOP!
28. RED GREEN REFACTOR

42. Take little steps!

83. SUMMARY
84. WHAT - imho - TDD IS ABOUT TDD is not only 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.
85. TESTER ! DEVELOPER How it brings us together - help developers to refine tests - build a balanced testing pyramid together Image src: https://giphy.com/gifs/dog-hug-sX755wvr2Q6gE
86. THANKS A LawhoooooOT
