@pytest.fixture(params=['a', 'b'])
def do_something(request):
    print request.param
    
    
@pytest.usefixtures(do_something, params=['c'])
def do_something_with_something_else():
    '''Like to pass a custom setof params to the fixture'''

as a kind of hack you could do something like this i guess:

@pytest.fixture(params=["a", "b"])
def do_something(request):
...

@pytest.fixture(params=["c"])
def do_otherthing(request):
return do_something(request)

@pytest.usefixtures("do_otherthing")
def test_some():
pass
