OpenCover is a code coverage tool for .NET and currently supports .NET 2, 3 and 4

OpenCover is a new attempt to build a code coverage utility to try and address some of the issues that have been encountered whilst maintaining PartCover.

The main aims of this project are:

  • Provide 32 and 64 bit support for .NET2 and .NET4
  • Better generics handling, though PartCover has been upgraded to handle .NET4 and generics (in both .NET2 and 4) it isn't pretty.
  • Simpler coverage handling
  • Better test support - the ultimate aim is to use the information to show what tests currently cover the code being worked on i.e. would it be possible to run those tests first and then the rest of the tests to provide faster feedback during development.
