Editor's Notes
- First was TDD Benefits of TDD: Focus, thinking, simplicity, regression suite, documentation Same can be applied at the feature/product level
- Different names. ATDD was about automating the application BDD used DDD ubiquitous language Step reusability GWT format
- All three hats are responsible to make a product that is easy to build and maintain, and also solves the customer’s problems.
- I want Kylo Ren and Han stare off I want a star destroyer in the beginning. Two death stars Yoda with a green saber Han is too old, we need fresh face Four death stars Yoda with a blue saber Jabba the hut running across the screen
