python unittest lambda函数

如何解决python unittest lambda函数

我在烧瓶1.1.2和下面的python 3.8中对api使用Marshmallow进行了单元测试

schema.py

class ListSchema(Schema):
   id = fields.Integer()
   name = fields.String()
   gone_date = fields.Function(lambda data: data.gone_date.timestamp())

main_service.py

class MainService:
   @classmethod:
   def get_list(cls):
      list_schema = ListSchema()
      list_data,total = Class.function_get_list_data
      list_data = list_schema.dump(list_data,many=True)

当我为函数get_list运行pytest时

mock = [(1,'Name_1',datetime.datetime(2020,8,20,0))],10
mock_data = mock.Mock(return_value=mock)
with mock.patch.object(Class,'function_get_list_data',mock_data):
   response = MainService.get_list()

我总是在模式中添加lambda函数时出错

AttributeError：“元组”对象没有属性“ gone_date”

在这种情况下，如何通过lambda函数通过或测试。我已经尝试使用raise unittest.skip，但这不是我的期望。我的功能仍然正常工作，仅在应用单元测试时出错。感谢您的帮助。
