In PyCharm, how do you add a custom parameter to pytest when running unittests?

Question

I'm running a Python unittest in pycharm. This executes the command:

/<path>/python /<path>/_jb_pytest_runner.py --target my_function_test_base.py::MyFunctionTestBase

Launching pytest with arguments my_function_test_base.py::MyFunctionTestBase in //tests

I would like to add a pytest option --tb=1 that I found in this answer: Make Python unittest show AssertionError but no Traceback

I don't know how to do that under PyCharm.

Answering on behalf of comments, indeed Additional Arguments in the Edit Configurations section does pass arguments through to py.test . My error was in misusing one of the arguments, obfuscating the fact that Additional Arguments was passing on the arguments as expected.
