Test Impact Analysis with Visual Studio 2010
This is the fifth 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.
Every time you modify your code, you need to run all tests cases again, to ensure no bugs were introduced in previously bug-free code; this is called regression testing. When the number of tests grows, the time to run all test gets longer. With test impact analysis, Visual Studio selects the minimal set of tests to cover modified code, optimizing the time required to do regression testing. In this video you will see a modification in the Subtract method of the Calculator class, and how Visual Studio selects the unit test that tests that method.
