dotCover calculates and reports statement-level code coverage in .NET Framework 1.0 to 4.5 applications, as well as in Silverlight 4 and 5. dotCover makes sure that developers know to what extent their code is covered with unit tests. It also helps QA engineers test software products as thoroughly as possible. Currently dotCover integrates into four versions of the IDE: Visual Studio 2005, 2008, 2010, and 2012.
