Hi,

It seems Bruno's reply got lost somewhere...

If I understand this correct then you have something like this:

foo.py:
   @pytest.fixture
   def fixtureMod_1():
       pass

   @pytest.fixture
   def fixtureFunc_1():
       pass

conftest.py:
   from foo import fixtureMod_1
   from foo import fixtureFun_1

test_x.py:
   
   @pytest.fixture
   def fixtureMod_2():
       pass

   def test_foo(fixtureMod_1, fixtureFunc_1, fixtureMod_2):
       pass
