Actual behaviour

zsh: no matches found: ./src/test_demo.py::test_parametrize_debug[a]

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

Using the following code, I select to debug one of the parametrized options. Doing run all appears to work.

import pytest


@pytest.mark.parametrize("ab", ["a", "b"])
def test_parametrize_debug(ab):
    assert ab != "c"
