Right, any "usefixture" needs to either have a global side effect
or stick some object to "self".  One easier way to get a tempdir
is this:

   class MyTest(unittest.TestCase):
   
        @pytest.fixture(autouse=True)
        def set_tmpdir(self, tmpdir):
            self.tmpdir = tmpdir

        def test_something(self):
            # access self.tmpdir

HTH,
