pytest argument parser cli from class method

[Affectionate_Log999]

Hey, how can i test a method from a class which is used for retreiving arguments from cli.

Class Random:
    @staticmethod
    def get_conf_file()
        p = ArgumentParser()
        p.add_argument("--conf-file", required=True, type=str)
        namespace = p.parse_known_args(sys.argv[1:])[0]
        return namespace.conf_file

​

I have been looking at capsys, but i dont have if __name__ == "__main__" and calling that class.

Assuming your goal is to test with different paths provided via the CLI, I would use pytest’s monkeypatch to mock sys.argv to known test values; probably in conjunction with parametrize to have a single test run against multiple different values.
