无法模拟第三方 api 调用

Question

我有一个执行第三方 API 调用的视图：

from .atoca_api_calls import atoca_api_call

def atoca_api_call_view(request):
  # some code
  data = atoca_api_call(**params)  # the actual API call happens in this func
  # some code

我的意图是只模拟 atoca_api_call() 函数而不是整个视图。

class AtocaTestCase(TestCase):
    def setUp(self):
      # some code

    @patch('crm.atoca_api_calls.atoca_api_call')
    def test_atoca_call(self, mock_atoca_api_call):
      mock_atoca_api_call.return_value = MagicMock(
        status_code=200,
        response=some_json # just returns some json
      )
      url = reverse('crm:atoca-api-call')  # url related to `atoca_api_call_view`
      response = self.client.post(url, some_others_params)
      # various asserts

测试工作正常，但 atoca_api_call() 未被模拟。我知道 where to patch:

@patch('crm.views.atoca_api_call', autospec=True)

提出 ValueError:

ValueError: Failed to insert expression "<MagicMock name='mock.__getitem__().__getitem__().__getitem__()().resolve_expression()' id='140048216397424'>" on crm.Company.atoca_id. F() expressions can only be used to update, not to insert.

这可能是一个简单的问题，我没有经验，非常感谢任何帮助。

Answer 1

我看到 atoca_api_call() 它被嘲笑了。问题是 return 值。

mock_atoca_api_call.return_value = MagicMock(
    status_code=200,
    response=some_json # just returns some json
)

我假设 JsonResponse 或 Response(data) 不确定您在做什么 return，这应该是一个正确的回应。尝试：

mock_atoca_api_call.return_value = JsonResponse(
    some_json # just returns some json
)
