Super-Charge Your Python Builds – Test What Matters, Stop Testing What Doesn't

This opensource project, called partialtesting, uses coverage data (based on Ned's coveragepy 5.0) to get a list of tests that should be run for every commit/Pull-request. The goal is to save time by only running relevant tests, instead of the entire test suite. The code and more details are available here https://github.com/man-group/partialtesting
