NUnit is a unit-testing framework for all .Net languages. Initially ported from
JUnit, the current production release, version 2.2, is the fourth major release of
this xUnit 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.
