How to run several parametrized test cases

[LuriaA]

Hi!
I have parametrized test test_login_fail in class TestLogin:

@pytest.mark.parametrize(
        "creds",
        [(SRS_USER,''),(SRS_USER,'invalid_pass'),('invalid_user',SRS_PASSWORD)],
        ids=['empty_pass','wrong_pass','wrong_user'])

How can I start, for example, only 'empty_pass' and 'wrong_user' cases?
I can start all cases by

-k "(TestLogin and (test_login_fail))" 

If I use-k "test_login_fail[wrong_user]" it works but it doesn't work with

-k "(TestLogin and (test_login_fail[empty_pass]))" 

or

-k "test_login_fail[wrong_user-empty_pass]"

or

-k "test_login_fail[wrong_user] or test_login_fail[empty_pass]"

How can I achieve my purpose?

I used this file

import pytest


class TestLogin:
    @pytest.mark.parametrize(
        'creds',
        [('foo', ''), ('foo', 'invalid_pass'), ('invalid_user', 'bar')],
        ids=['empty_pass', 'wrong_pass', 'wrong_user'],
    )
    def test_login_fail(self, creds) -> None:
        pass

and your last attempt works for me:

$ pytest x.py -v -k "test_login_fail[wrong_user] or test_login_fail[empty_pass]"

Perhaps try again?

I've updated pytest and it started to work with

-k "TestLogin and (test_login_fail[empty_pass] or test_login_fail[wrong_user])"

Thanks!
