What is TDD?
Introduction to Test Driven Design (TDD)
http://en.wikipedia.org/wiki/Test-driven_development
The book I am reading now:
Test-Driven Development in Microsoft .Net
http://www.amazon.com/gp/product/0735619484/104-6335027-2160757?v=glance&n=283155
In this book, author uses NUnit(http://www.nunit.org/index.php) as the TDD tool. Since I used the Visual Studio Team System, and it has supported TDD. So no need to install NUnit. Just use VSTS. and it is cool!
