@mr-c, Can you list out the steps to generate latest test coverage locally? Also, I'm thinking of setting coveralls (to measure test coverage for each PR) for this repository. Better tests coverage is becoming increasingly important as we're gonna support multiple versions of Python. 😄

@manu-chroma make coverage-report should do the trick. Coveralls would be great, yes!
