I often have a use case like the following contrived example:

@pytest.fixture def a(): return 'a' @pytest.fixture def b(): return 'b' @pytest.mark.parametrize('arg', [a, b]) def test_foo(arg): assert len(arg) == 1

This doesn't currently do what's intended i.e. arg inside the test function is not the fixture value but the fixture function.

I can work around it by introducing a "meta fixture", but that's rather ugly:

@pytest.fixture(params=['a', 'b']) def arg(request, a, b): return {'a': a, 'b': b}[request.param] def test_foo(arg): assert len(arg) == 1

It would be convenient if a syntax like in the first case was supported.
