Issues when parametrize argnames contains a list

[smarie]

IndexError: list index out of range or AttributeError: 'list' object has no attribute 'replace' can happen even with normal pytest parametrize when argnames contains a list/tuple.

For example this fails :

import pytest
from pytest_cases import pytest_fixture_plus


@pytest_fixture_plus
@pytest.mark.parametrize(['c', 'd'], [(0, 0), (1, 1)])
def f(c, d):
    pass

@pytest.mark.parametrize(['a', 'b'], [(0, 0), (1, 1)])
def test_dummy(a, b, f):
    pass
