The unittest test discovery right now only looks into sub-packages if they contain a `` file. That's an unnecessary requirement, as packages are also importable if only `__init__.pyc` is present.

Python has stopped supporting .pyc-only distributions - see - and so, while what you are seeing is inconsistent with import in some older python's, it is not a bug in newer Python's, and I don't see any benefit in doing a backport-only fix for it.

Sorry, I missed the little footnote on case 4 about still supporting source-less distributions. I guess in that context we do still need to support this.

However - please check that this does indeed happen on Python master - 3.6. unittest does evolve and if you're testing on 2.7 or something your bug is perhaps already fixed.

Please see Issue 26859; I think it is describing the same problem, and a fix is proposed (although no regression test)
