Recently noticed DelphiCodeCoverage had a new home on GitHub, with several updates that make it stable. I had been it in a previous incarnation to assess DWScript test coverage, and help pick which aspects of the engine were in need of extra tests.
The DWScript tests can be quite heavy on exceptions, sub-processes and multithreading. The tests go after checking all things that should fail do fail as they should. That was a bit too much stress for the previous versions, which would occasionally crash. I am happy to say those issues are gone from the current version of DelphiCodeCoverage!
