If i define a custom fixture like:

@pytest.fixture(scope='module')
def my_fixture(mocker):
// code using mocker

class TestMyModule(object):

def test_one(self, my_fixture): // test code 

When i run this i get:
ScopeMismatch: You tried to access the 'function' scoped fixture 'mocker' with a 'module' scoped request object, involved factories

I'm i doing something wrong to do something like this? is there some reason why this is not supported?

Thanks.
