Test a decorated function in Python

Question

I have a Python function which is decorated.

    @retry_if_access_token_expired(app_id)
    def add_something(
        self,
        *,
        argument1,
        argument1 = None,
    ):

          """adding something"""

I've written tests for the given as below.

    @patch("other inside function to mock")
    @patch("other inside function to mock 2")
    def test_add_something(
        self, mock_1, mock_2
    ):
        """ some logic to test the add something method """

But I am getting this error that says add_something takes one positional argument:

TypeError: add_something() takes 1 positional argument but 3 were given

How can I fix it?
