In this session, we will discuss how to do Test Driven Development (TDD). We will start our Jedi training from the basics of what TDD is, why you should be doing it, and how it improves the quality of your software. We will also talk about what TDD is not and where developers often go wrong with TDD and succumb to the dark side. All along the way, we will do live coding demos so that you can see TDD in action. Demos will be in C#, but the TDD concepts apply to any language.
