NUnit Test Generator takes existing public classes, properties and methods in your C# or VB.NET source files and generates stub tests.  The NUnit Test Generator is template based so it is easy to modify the output.  The NUnit Test Generator has advanced features such as expanding abbreviations and extracting documentation from source classes.  The NUnit Test Generator can create C# or VB.NET tests.  It has templates to create NUnit, xUnit, MbUnit, csUnit, and Microsoft Unit Tests.  Plus you can easily create your own templates.

You can generate test stubs for your entire project by simply choosing a Visual Studio project file.  You can run NUnit Test Generator with the same output directory several times.  It will add missing tests to your existing test files.
