[pytest-dev] Parametrized fixture fails when using unittest

[Nikolaus Rath]

Hi,

Seems you can't even trust copy and paste anymore... no idea how that
happened. Here's the missing part (so no, self is not missing):

[...]
@pytest.mark.usefixtures('param2', 'param1a')
class TestClass(unittest.TestCase):
    def test_method(self):
        if self.param2[0] == 1:
            assert self.param1a == 0
        else:
            assert self.param1a == 7

Thanks,
-Nikolaus
