[TIP] pytest: Setup/TearDown with fixtures

[Laszlo Papp]

Right, I think this could be added to the official documentation to
have a copy/pasteable example in there:

class TestFoo:
    @classmethod
    @pytest.fixture(scope="class", autouse = True)
    def setup(self, request):
        self.session = foo.session()
        def tearDown():
            session.logout()
        request.addfinalizer(tearDown)

I am yet to test this in practice, but this simple snippet would have
been a timer-saver for me when writing this basic functionality ...
