Test driven development (TDD) and Refactoring legacy code

I found this video from Sandro Mancuso really interesting. It's all about legacy code, something a developer use to face really often and how to do it in a proper way. Sandro will teach you in the video how to create your own tests using TDD and some creative ways to manipulate the behaviour of legacy classes in order to provide the best way to test an application.

I hope you enjoyed it and I wish you can use some of the good practices showed in the video in your next project.
