NUnit is an open source unit testing framework built for the .NET Framework. NUnit allows you to write tests in the language of your choice to test a specific function of your application. Unit tests are an excellent way to test the functionality of your code when you first write it, and also to provide a method for regression testing of your application. The NUnit application provides a framework for writing unit tests, as well as a graphical interface to run these tests and view the results.
