Auto-generation of .NET unit tests [closed]

Take a look at Pex. Its a Microsoft Research project. From the website:

Pex generates Unit Tests from hand-written Parameterized Unit Tests through Automated Exploratory Testing based on Dynamic Symbolic Execution.

UPDATE for 2019:

As mentioned in the comments, Pex is now called IntelliTest and is a feature of Visual Studio Enterprise Edition. It supports emitting tests in MSTest, MSTest V2, NUnit, and xUnit format and it is extensible so you can use it with other unit test frameworks.

But be aware of the following caveats:

  • Supports only C# code that targets the .NET Framework.
  • Does not support x64 configurations.
  • Available in Visual Studio Enterprise Edition only
