DjangoRestFramework: Unit Testing AssertionError: 404 != 200 while Test update

Я начал писать модульные тесты для своих API, но застрял на обновлении данных пользователя, получив ошибку утверждения 404!=200. Я делюсь своим кодом для справки. Пожалуйста, сообщите мне мою ошибку и краткое объяснение, так как я новичок в django rest.

Я создал только один класс "class TestUser(APITestCase):" для тестирования 2 API это нормально, так как я расширяю URL в патче клиента обновления?

        for the currently authenticated user.

            user_data= self.request.user.id

            return data
