NUnit is a unit-testing framework for all .Net languages. Initially ported from JUnit, the current release, version 2.2, is the fourth major release of this Unit based unit testing tool for Microsoft .NET. It is written entirely in C# and has been completely redesigned to take advantage of many .NET language features, for example custom attributes and other reflection related capabilities. NUnit brings xUnit to all .NET languages.
