How to run different Pytest arguments or marks from VS Code test runner interface?

Question

I'm having trouble getting the VS Code PyTest code runner to work the way I'd like. It seems pytest options may be an all-or-nothing situation.

Is there any way to run different sets of PyTest options easily in the VS Code interface?

For example:

1. By default, run all tests not marked with @pytest.mark.slow.

   • This can be done with the argument -m "not slow"
   • But, if I put that in a pytest.ini file, then it will never run any tests marked slow, even if I pick that particular test in the interface and try to run it. The resulting output is collected 1 item... 1 item deselected.

2. Run sometimes with coverage enabled, and sometimes without.

The only way I can see to do this is to run PyTest from the command line, which then loses the benefit of auto-discovery, running/debugging individual tests from the in-line interface, etc.

What am I missing?

Note: Currently using VS Code 1.45.1, Python 3.7.6, and PyTest 5.3.5

You're not missing anything. There currently isn't a way to provide per-execution arguments to get the integration you want with the Test Explorer.
