NUnit 2.0 is an excellent example of idiomatic design. Most folks who port xUnit just transliterate the Smalltalk or Java version. That's what we did with NUnit at first, too. This new version is NUnit as it would have been done had it been done in C# to begin with. Kent Beck

What Is NUnit?

NUnit is a unit-testing framework for all .Net languages. Initially ported from JUnit, the current production release, version 2.5, is the sixth 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.

About Us

The NUnit development team currently consists of Charlie Poole, Jamie Cansdale and Gary Feldman. Past developers include James W. Newkirk, Alexei A. Vorontsov, Michael C. Two and Philip A. Craig. We would also like to thank the following people for their contributions and support: Doug de la Torre, David White, Ethan Smith, Al Gonzalez, Ron Jeffries, and Rob Jeffries. A special acknowledgment needs to be sent to Kent Beck and Erich Gamma because without their efforts none of this would have been possible. Site design by Anne Lewis.

Donations

The NUnit team invests a great deal of time and effort to make NUnit a useful tool. In addition, we have expenses. We have to purchase domain names, arrange for web site hosting and acquire equipment.

Making a financial contribution is one way in which you can help us ensure that NUnit continues to develop and remains free and open software. For more information or to view a list of donors, see our Donations page.
