I guess it's worth taking a look at some more complex open source Python projects. I think pandas [1] is a pretty good example, with a relatively large amount of Python and Cython code. They start off with a pretty decent amount of unit tests (84% coverage) and make sure it's visible to developers using: - Travis [2] (has to pass on pull requests too before contributions are accepted) - Coverage [3] There's also Code Climate [4] for some more introspection.
