Editor's Notes
- #4: TDD Intro Is all code guilty until proven innocent??? can we find out?
- #5: why tdd: 30 min Steps to TDD: 90 min Workshop for doing red green test: 120 min
- #9: write Red test. write greed code that passes the test. refactor your code.
- #13: Make a workshop for writing a test first then code example write red test. write greet code do the cycle again. do fibonacci example.
