What tools do you use for testing in .NET? This is a question many new developers who come to the land of TDD have for experienced developers. New developers are often not sure which testing framework is the best one to use.
NUnit is a testing framework that has become the standard for testing in .NET. NUnit is a member of the XUnit family of testing languages, and as such is an open-source tool. There are other testing frameworks out there; however, none have had the level adoption that NUnit has. We plan on showing you how to install NUnit, either through the NUnit web site or through NuGet. We will finish this with a TDD primer to whet your appetite for using NUnit in the case-study chapters.
