Unit Tests generation with Pex using Visual Studio 2010 and C# 4.0

This is the third post of a series about testing tools and techniques using Visual Studio 2010, Team Foundation Server 2010, Microsoft Test Manager 2010, and C# 4.0.

In the first post I showed how Visual Studio allows test driven development and in the second post how to automatically generate test cases from code.

Pex is a tool created by Microsoft Research that integrates into Visual Studio and automatically generates parameterized unit tests from code. In addition, Pex analyzes code under test and automatically generates test cases with high code coverage. In this video you will see how to create a unit test for a Factorial method of a Calculator class using Pex.

You can find more details about Pex, including sample code, in this post.
