#!python
import pytest

@pytest.fixture
def app(scope='session'):
    print('fixture.app')

@pytest.fixture
def client(app):
    print('fixture.client')

@pytest.fixture
@pytest.mark.usefixtures('client')
def user_tom():
    print('user jessie')

def test_a(user_tom):
    print('test_a')
    assert False

In above code, 'client' fixture does not run, but it runs if put 'client' into user_tom()'s args list.

usefixtures (and other markers like parametrize for that matter) are not advertised to work on fixture functions, only on test functions. I don't see the advantage of providing usefixtures on a fixture function, in particular.

If you like to see marker support on fixture functions, please open an enhancement issue and provide some ideas/input on the semantics on that. thanks.
