Test-driven development in .NET yields complete unit test coverage

TestDriven.NET is a third-party unit testing add-in for Visual Studio that helps developers turn this concept from breathless prose into hard-coded reality. It supports a variety of unit testing frameworks, including Visual Studio Team System (aka MSTest), MbUnit, xUnit, and NUnit. TestDriven.NET works with all .NET Framework versions. Earlier iterations of TestDriven.Net were developed specifically for NUnit and went by the NUnitAddIn product name.

TestDrive.NET supports the following kinds of functionality:

• Single-click execution of unit tests within any method, class, namespace, project or solution right from inside Visual Studio.
• Snap evaluations for methods or properties using simple ad-hoc tests (right-click and select Run test(s) or Test With > Debugger).
• Ability to view any module or stack frame inside .NET Reflector while debugging inside Visual Studio.
• Executes inside its own process context to permit testing sans side effects.
• Support for debugging and code coverage analysis on any target tests.
• Works with all major .NET languages, including C#, C++, F#, and Visual Basic.
• Works with Visual Studio 2003, 2005, 2008 and 2010, running on 32- and 64-bit versions of Windows 2000, XP, Vista plus Windows Server 2003 and 2008.
