As "prior art" the way that pytest does this is to have parametrized tests show up as separate tests:

    import pytest

    @pytest.mark.parametrize("i", range(1, 3))
    def test_something(i):
        if i > 1:
            pytest.skip('Not supported')
        assert i == 1

    @pytest.mark.parametrize("i", range(1, 3))
    def test_something_else(i):
        assert 3 > i >= 1


Running `pytest -v` for this gives:
