Djangoクライアントの取得：TypeError：__ init __（）は1つの位置引数を取りますが、2つが指定されました

私は次の簡単なテストをしています：

class DeviceListTests(APITestCase):
    def test_devices_list(self):
        self.user = UserFactory()
        self.device = DeviceFactory(name="SoundTalks_device")
        self.client.force_login(self.user)
        response = self.client.get(
            reverse("device-list")
        )

Python / Djangoは次のエラーを返します：

response = self.client.get(
                reverse("device-list")
            )

ただし、これは簡単なリクエストです。次のエラーが発生します。
