我目前正在通过Python速成课程学习，在测试一章中遇到了问题。我用一把梳子梳了一下，向我想象中的橡皮鸭解释了一下，根本看不到我哪里出了问题。

运行测试文件可以使我“在0.000秒钟内运行0个测试”，但看不到任何错误。 第一个块来自我的文件“ survey.py”，第二个块是测试文件“ testSurvey.py”

我们非常感谢您的帮助。

class AnonymousSurvey():

    def __init__(self,question):
        self.question = question
        self.responses = []

    def showQuestion(self):
        print(self.question)

    def storeResponse(self,newResponse):
        self.responses.append(newResponse)

    def showResults(self):
        print("The survey results are")
        for response in self.responses:
            print("-- " + response)



import unittest

from survey import AnonymousSurvey

class TestAnonymousSurvey(unittest.TestCase):
    def TestStoreSingleResponse(self):
        question = "What is your favourite language?"
        mySurvey = AnonymousSurvey(question)
        responses = ["English","Latin","Franglais"]
        for response in responses:
            mySurvey.storeResponse(response)

        for response in responses:
            self.assertIn(response,mySurvey.responses)

unittest.main()
