Running pytest.main in python code always returns value of None when argument is clearly set

Question

This is the test file that i am running.

# this file is test_define.py

import pytest

def test_it(aw_name):
    print(aw_name)

if __name__ == '__main__':
    pytest.main(['-s', 'v', '--aw_name', 'boom', 'test_define.py'])

This is the conftest file in the same directory

# conftest file
import pytest

def pytest_addoption(parser):
    parser.addoption("--aw_name", action="store")

@pytest.fixture
def aw_name(request):
    return request.config.getoption("aw_name")

Running this in terminal works properly and prints out:

% pytest -s -v --aw_name boom test_define.py

But when I run in pycharm using the play button for the "if name == 'main':" I always get a value of None. Am i missing something in the pytest.main call? I've also double checked that the interpreter is set to the same as the terminal.
