MbUnit is a generative unit test framework for the .NET Framework.
MbUnit provides advanced unit testing support with advanced fixtures to enable developers and testers to test all aspects of their software.
There are two current versions of MbUnit, v2 and v3.
MbUnit v3 is the current version of the MbUnit Framework. It is based on the Gallio Test Automation Platform which provides a stunning array of interoperable test tools. MbUnit v3 has been rewritten from the ground up to provide a compelling suite of testing features, native support for .NET 2.0 and .NET 3.5, better documentation, and cross-platform compatibility with Mono.
MbUnit v2 is the older version of the MbUnit Framework. It is still actively maintained for the benefit of existing users.
