async test does not run in pytest

I am trying to test an async function. Thus, I have an async test. When I use pycharm to set breakpoints in this test, they don't break. The things which are supposed to print to console do not print. And, the test takes 0 seconds. pytest lists the test as PASSED, but it clearly isn't actually executing the code in context.

Here is the code:

import unittest.mock
import pytest
from app.listener import ListenerCog


class ListenerCogTestCase(unittest.TestCase):
    def setUp(self):
        # Create a mock discord.Client object
        self.client = unittest.mock.Mock()

        # Create a ListenerCog instance and pass the mock client as the bot attribute
        self.listener_cog = ListenerCog(self.client)

    @pytest.mark.asyncio
    async def test_on_ready(self):
        # Call the on_ready method of the ListenerCog instance
        await self.listener_cog.on_ready()

        # Assert that the "Running!" message is printed
        self.assertIn("Running!", self.stdout.getvalue())

What I've tried:

• enable python.debug.asyncio.repl in pycharm registry
• add arguments to pytest including --capture=no -s and --no-conv

Nothing seems to be working. Would really appreciate some guidance here if anyone is accustomed to debugging async tests.
