Hi!

You didn't include the test_method, maybe you just forgot the 'self' as first parameter?

Hello,

I don't understand why the following test fixture works for the test
function, but fails for the test method. Am I doing something wrong, or
is this a bug?

$ cat t0_mine.py
import pytest
import unittest

@pytest.yield_fixture(params=(0,1,2))
def param1(request):
 if request.param == 1:
     pytest.skip('not so good')

 yield request.param

@pytest.fixture(params=('a','b'))
def param2(request, param1):
 return (param1, request.param)

@pytest.fixture()
def param1a(request, param1):
 if param1 == 1:
     return 0
 else:
     return 7

def test_function(param2, param1a):
 if param2[0] == 1:
     assert param1a == 0
 else:
     assert param1a == 7

@pytest.mark.usefixtures('param2', 'param1a')
