NCoverCop is a custom NAnt task that fails your build when your code coverage drops by using NCover. It also tells you what code has become untested. This promotes TDD. See NAnt [http://nant.sourceforge.net/] and NCover [http://www.ncover.com/]
A code coverage console app for wrapping MsTest executed tests for Visual Studio for Testers. The app extracts coverage data from a binary (*.coverage) file, generated by MsTest into an XML file which can be used in your build process.
