Oh, I forgot something about Codecov: it took me 2 minutes to understand why a PR gets the red icon whereas all tests pass and the merge button was waiting for my click. In fact, Codecov failed but the test isn't blocking. I would expect the green icon on the overall list of PR.

Well, it's not blocking, just surprising the first time.

It may be annoying when you really want to list PR where tests fail, for example to reschedule Travis jobs if we fix a bug in master (which caused a test failure).
