test_files under TestEgg also needs to be marked. test_missing_metadata doesn't need to be marked since it passes without zlib. Log of my test output as below :

test_case_insensitive (test.test_importlib.test_zip.TestEgg) ... ERROR

Thanks for double checking @tirkarthi! I updated the marked tests as suggested.

My instinct would be to skip all of the tests in the file. Even though they don't fail, their assertions aren't being adequately exercised. I don't feel strongly about it, especially since each test has to be marked individually. If it were possible to mark the whole file for skip (such as you can with pytest), I'd recommend that. I don't see that there's such a feature in unittest.

Does it work if you decorate the two classes instead?

[jaraco]

I'm happy with this regardless of how it's implemented.

[tirkarthi]

Yes, decorators work skipping the classes. I felt it might unintentionally skip tests that don't require zlib too and hence listed the tests.

[rth]

Thanks for the feedback. I reverted to decorating both classes as suggested. Even if two tests pass without zlib, they still apply to the zip module which generally doesn't work without zlib. So I'm not sure that not skipping them provides much relevant information indeed.

Though I can go back to the previous solution if it has more consensus.

@jaraco: Please replace # with GH- in the commit message next time. Thanks!

Looks great. Thanks!
