    res = r.get_from_params(**{"obj": "foo", "a": 1, "b": 2})
    assert res == {"a": 1, "b": 2}

    res = r.get_from_params(**{})
    assert res is None

def test_meta_factory():
    def meta_1(fn, args, kwargs):
        return fn

    def meta_2(fn, args, kwargs):
        return 1

    r = Registry("obj", meta_1)
    r.add(foo)

    res = r.get_from_params(**{"obj": "foo"})
    assert res == foo

    res = r.get_from_params(**{"obj": "foo"}, meta_factory=meta_2)
