Unit test of endpoint decorated with Flask @auth.login_required decorator

I'm using Flask-HTTPAuth for authentication, Flask-login for login and want to add unit tests for endpoint decorated with @auth.login_required(scheme="Bearer"):

endpoints.py

class UserData(Resource):
    @auth.login_required
    def get(self, user_id):
        user = db_models.User.query.get(user_id)
        return result

authent.py

@auth.verify_token
def verify_token(token):
    data = token_serializer.loads(token)
    return data.get("username", False)

But got stuck with mocking (it doesn't work):

test.py

@mock.patch("myapp.auth")
@mock.patch("myapp.db_models.User")
def test_get_user(self, mock_user, mock_login):
    with app.test_client() as client:
        mock_login.verify_token.return_value = TEST_USER["username"]
        mock_login.login_required.return_value = True
        mock_user.query.get.return_value = TEST_USER
        response = client.get("/user/100000")
        self.assertIsNotNone(response)
        self.assertIsInstance(response.get_json(), dict)

And the second approach:

test.py

@mock.patch("myapp.auth.login_required", return_value = True)
@mock.patch("myapp.db_models.User")
def test_get_user(self, mock_user, mock_login):
    with app.test_client() as client:
        mock_user.query.get.return_value = TEST_USER
        response = client.get("/user/100000")
        self.assertIsNotNone(response)
        self.assertIsInstance(response.get_json(), dict)

Could you please help me to figure out how to do it in the right way?

Thank you for your help!
