This causes fixture 'self' not found on the TestCase class:

Notice that with the test_thing_pytest function, normal pytest.mark.parametrize handles self just fine.

Thanks for reporting this ! I'll have a look

Fixed in 1.11.5, it should be deployed in a few minutes. Thanks again for reporting !

Bad luck : the travis CI system has global issues syncing with github, and in particular it can not run "tagged" builds, which I use for pypi releases.

The release will be done when travis is fixed. Sorry for the delay :(
