Open Source C# Unit Testing Tools

NUnit is a unit-testing framework for all .Net languages. Initially ported from JUnit, the current production release, version 3, has been completely rewritten with many new features and support for a wide range of .NET platforms. NUnit is intended to be extensible. We can't do everything for everybody but we want to make it reasonably easy to extend NUnit. In many cases, users will be able to implement a special feature outside of our scope by simply creating a new attribute that embeds the required logic. In other cases, particularly in extending the engine, we rely on a plugin architecture. When running tests in a separate process, the console and gui runners make use of the NUnit Agent program, nunit-agent.exe. Although not directly run by users, nunit-agent does load and execute tests and users need to be aware of it, especially when debugging is involved.

NUnit brings xUnit-style unit-testing to all .Net languages. Although we no longer host our development on Sourceforge, our latest releases are always available here, as well as at our current development site at http://launchpad.net/nunitv2 Please report bugs at http://bugs.launchpad.net/nunitv2 You can browse or download the current source code at http://code.launchpad.net/nunitv2

Otter Unit Test Framework is a tool which performs automated Unit Test in .NET 4,0 or above applications. It works similarly to the JUnit and it used as part of the application being tested, in MS Web or C# Developer 2010. Older versions (00.05 and below) were developed for MS Visual Studio 2005 and can still be downloaded. For them, a MS Visual Studio Plugin was developed and in the project´s home page you can find its documentation.
