Python匿名调查并测试类（unittest）

class AnonymousSurvey:
    #收集匿名调查问卷的答案

    unittest.main()
#使用setUp方法简化测试
class TestAnonymousSurvey(unittest.TestCase):

        self.my_survey.store_response(self.response[0])
        self.assertIn(self.response[0],self.my_survey.responses)#(self.my_survey).responses. 是 AnonymousSurvey中的self.responses，与下面的self.responses的意思不一样
        for response in self.responses:#self.responses的意思是setUp方法中的一组答案。在55行
            self.my_survey.store_response(response)
        for response in self.responses:
            self.assertIn(response,self.my_survey.responses)
if __name__=='__main__':#在这里可以省略这个判断
    unittest.main()
