TDD has been around since 2002 but today still too many people out there have little understanding of what it actually is. This slide deck tries to help to understand that TDD is not a method to create tests but a truly genuine way to do programming and that programmers like no other benefit from the technique. Hopefully, this will lead more people to embracing it.
Test Driven Development: More Development Than Ever
- 1. More Development Than Ever Test Driven Development
- 2. Team Lead at EPAM Agile practitioner (CSM) Trainer Public speaker
- 4. Writes perfect code with no bugs Also saves the world during coffee breaks
- 5. Im more like this guy
- 6. Billions of years ago In the stone age of computer science 息 Mutatis mutandis
- 7. 息 Computer History Museum
- 8. 199495: rediscovered by Kent Beck 息 Improve It
- 9. 2014 1995 = ?
- 10. 2014 1999 = 15
- 11. 2014 2002 = 12
- 12. I spend too much time writing tests.
- 13. TDD Non-TDD Think Test Code Think Code
- 14. Think Test Code Think Code Debug!!!
- 15. In reality Think Test Code
- 16. TDD vs. debugging only Shorter feedback cycle Reusable test suite Code instead of pen and paper Genuine feeling of completeness Predictability
- 17. I spend too much time writing tests. I would have spent this time anyway.
- 18. It doesnt apply exactly to my case.
- 19. Legacy code
- 20. Front-end
- 21. Embedded systems
- 22. It doesnt apply exactly to my case. Theres a fair chance my case is not unique.
- 23. Im new to the technology, I cant test what I dont know.
- 24. Its OK to use a debugger Its OK to go back and forth
- 25. Test is a hypothesis you can prove on the spot.
- 26. Im new to the technology, I cant test what I dont know. TDD in fact helps me learn.
- 27. I have to modify the code too often, my tests become waste.
- 28. Think Test Code Refactor
- 29. Think Test Code Refactor
- 30. I have to modify the code too often, my tests become waste. Code without tests is non-existing to me.
- 31. My project is too agile, dont have time for tests! Well
- 33. Requirements Waterfall Design Implementation Verification Maintenance
- 35. Agile Requirements Design Implementation Verification Maintenance Requirements Design Implementation Verification Maintenance Requirements Design Implementation Verification Maintenance
- 36. My project is too agile, dont have time for tests! I use TDD to build in quality into my code.
- 38. TDD is a way to prepare your workplace and keep it safe 息 johnjazz
- 39. There strategy And theres execution And execution is hard
- 42. References Ten Years Of Test Driven Development Why does Kent Beck refer to the "rediscovery" of test-driven development? (Quora) Waterfall model (Wikipedia) JQuery
