As a developer you take pride in your work (as you should). So it's frustrating when bugs happen. How do you prevent them? Well, the honest answer, is you can't - at least not 100%. But you can make sure your code does what you expect it to do! In this session, I show you TDD (Test Driven Development), BDD (Behavior Driven Development), and TED (Test Eventual Development). I will also show you their strengths and weakness, and how to decide which type (or combination of types) to use in different scenarios.
