This switches most tests over to use pytest as the runner instead of unittest (taking advantage of the fact that pytest can run unittest based tests). There were a couple tests that had failures when swithing to pytest: config/tests/unit-expandlibs.py xpcom/idl-parser/xpidl/runtests.py For these tests, I added a runwith='unittest' argument so that they still run the same way as before. Once we fix them to use pytest, the unittest logic in mozunit.py can be deleted. MozReview-Commit-ID: Gcsz6z8MeOi --HG-- extra : rebase_source : 3c762422ce0af54cbbe7d9fc20085a2d1ebe7057
