NUnit 2.6.3 / 2.9.6 Description:
NUnit is an open source and completely free unit testing development framework designed especially for all .NET languages, initially ported from JUnit, running on Mono and Microsoft .NET. Being written entirely in C#, NUnit has been designed to take advantage of the many features of .NET languages, such as custom attributes, lambda expressions, generics and other reflection related capabilities. NUnit has been designed to bring xUnit to all .NET languages. Starting with version 3.0, NUnit is being split into several loosely coupled projects. It is a platform-independent application that supports Linux and Microsoft Windows operating systems.
