In this tutorial, I will show you how to implement an application: Buy Some Milk by applying TDD (Test-Driven Development). I found that with TDD you can modify your code later with more confidence - and I believe that's the most important part of a developer's coding experience.

I just found it's too long to put the content into one video, so I have to split it into three parts.

Table of Contents:

01:13 - Create an empty app
