Unable to combine xfail and parametrize

[pablojadz]

Thanks for a great package

I know that you can do things like

@pytest.mark.parametrize(
    "test_input,expected",
    [
        ("3+5", 8),
        pytest.param("1+7", 8, marks=pytest.mark.basic),
        pytest.param("2+4", 6, marks=pytest.mark.basic, id="basic_2+4"),
        pytest.param(
            "6*9", 42, marks=[pytest.mark.basic, pytest.mark.xfail], id="basic_6*9"
        ),
    ],
)

But the question is how to handle the case where you have combination of parametrized parameters.

I want to mark the test where param1=1 and param2=1 as xfail. Other than explicitly doing the combination of param1/2 myself, is there a way I could do this?

@pytest.mark.parametrize('param1', [0, 1])
@pytest.mark.parametrize('param2', [0, 1])
def test(param1, param2):
    if param1 and param2:
        raise ValueError

Ideally the solution would be something like

@pytest.mark.parametrize('param1', [0, 1])
@pytest.mark.parametrize('param2', [0, 1])
@pytest.mark.xfail(['param1=1', 'param2=1'])
def test(param1, param2):
    if param1 and param2:
        raise ValueError

thanks for reading

Hi @pablojadz,

is there a way I could do this?

You can call pytest.xfail explicitly inside the test:

@pytest.mark.parametrize('param1', [0, 1])
@pytest.mark.parametrize('param2', [0, 1])
def test(param1, param2):
    if param1 and param2:
        pytest.xfail(reason="param1 and param2 are 1")

great, thanks for the info, that works
