Howdy all, Recently we've been playing with tracking our code coverage in Services projects, and so far it's been pretty interesting. We've learned about where the gaps are in our testing (which has even revealed holes in our understanding of our own specifications and use cases), and had fun watching the coverage climb with (nearly) each pull request. I've slapped together some notes about our experience here: https://github.com/wikimedia/restbase/tree/master/doc/coverage#code-coverage I'd love to hear your thoughts and learn about your related experiences. What are your favorite code coverage tools and services? Cheers! James
