Code coverage for open source .NET with AppVeyor and Coveralls

Code coverage is a useful metric of the quality of your code. It shows how much code is being covered by unit tests. It doesn’t necessarily mean that the unit tests are well written, but no metric can probably tell you that. However, aiming for a specific code coverage, let’s say 70%, is a good practice, because failing to meet the goal might mean somebody didn’t write enough unit tests.

I’d like to have code coverage as part of the CI I had set up in a previous post with Travis. The bad news is that code coverage and Mono seem to be strangers. There is an open source module called monocov but I couldn’t get it to work. In fact in the homepage it says it’s not maintained. In my opinion, these kind of tools are essential and they should be included in the core Mono package. I hope they change this some┬áday.

That’s why sometimes I like to code a bit in C# at home. That can be either on Windows or on a Mac with Mono. The problem with Mono is that things can always be a bit different and require some extra effort. Continue reading “Troubleshooting TypeLoadException in mono”
