pytest fixture of fixtures

Question

I am currently writing tests for a medium sized library (~300 files). Many classes in this library share the same testing scheme which were coded using pytest:

One solution I found is to abuse the test cases as following:

from test_for_class_a import *
from test_for_class_b import *
from test_for_class_c import *

list_of_all_fixtures = []


# This will force pytest to generate all sub-fixture for class a
@pytest.mark.usefixtures(setup_class_a)
def test_register_class_a_fixtures(setup_class_a)
    list_of_fixtures.append(setup_class_a)


# This will force pytest to generate all sub-fixture for class b
@pytest.mark.usefixtures(setup_class_b)
def test_register_class_b_fixtures(setup_class_b)
    list_of_fixtures.append(setup_class_b)


# This will force pytest to generate all sub-fixture for class c
@pytest.mark.usefixtures(setup_class_c)
def test_register_class_b_fixtures(setup_class_c)
    list_of_fixtures.append(setup_class_c)


# This is the real test to apply on all fixtures
def test_all_fixtures():
    for my_fixture in list_of_all_fixtures:
        # do something with my_fixture

This implicitly rely on the fact that all test_all_fixture is executed after all the test_register_class*. It is obviously quite dirty but it works...
