Python unittest python单元测试：已达到模拟递归限制

模拟第三方api调用并修补它们以测试api调用

@mock.patch('payments.tests.stripe_mock.StripeWrapper.add_card')
@mock.patch('payments.tests.stripe_mock.StripeWrapper.get_customer')
def test_card_1(self, _mock_customer, _mock_card):
    post_data = {"number": 1233}
    response = self.client.post(reverse("card-list"), data=post_data)
    self.assertEqual(response.status_code, status.HTTP_201_CREATED)

api调用工作正常，但在api调用发送响应时，它抛出以下错误

这个堆栈跟踪完成了吗？谁称之为模拟？@Micheled'Amico post更新了完整的stacktrace。我现在没有时间深入研究这个问题，但是像

add\u card

或

get\u customer

返回对象这样的接缝是由框架装饰的。尝试创建此对象的伪对象，并使用

return\u value

返回伪对象，而不是

MagicMock

正确，我已经解决了如何设置模拟对象返回数据的问题。
