I have some test methods named test_01_login_subscribe and test_02_failed_subscription (among others with different numbers). If I want to run the first, I can execute either of the following commands and it will only run test_01_login_subscribe. The same idea applies to the second test.

pytest -k test_01
pytest -k 01

I can also run both tests and no others by using one of these commands:

pytest -k "test_01 or test_02"
pytest -k "_01 or _02"

The following command, however, does not work. When I run this command, every single test in my suite is triggered:

pytest -k "01 or 02"

The following commands raise an exception:

pytest2 -k "01_ or 02_"
pytest2 -k "01_login_subscribe or 02_failed_subscription"

Here is the full output for the above command:
