class AnonymousSurvey():
	'''收集匿名调查问卷的答案'''
	
	def __init__(self,question):
		'''储存一个问题并为储存答案做准备'''
		self.question=question
		self.responses=[]
		
	def show_question(self):
		'''显示调查问卷'''
		print(self.question)
		
	def store_response(self,new_response):
		'''储存单份调查问卷'''
		self.responses.append(new_response)
		
	def show_results(self):
		'''显示收集到的答案'''
		print("survey results:")
		for response in self.responses:
			print('-'+response)

用于测试的类

python 复制代码

import unittest
from survey import AnonymousSurvey

class TestAnonymousSurvey(unittest.TestCase):
	
	def test_store_single_response(self):
		'''测试一个答案也会被妥善储存'''
		question="What language did you first learn to speak?"
		#survey的属性question
		my_survey=AnonymousSurvey(question)
		#形成实例my_survey
		my_survey.store_response('english')
		#实例.方法名（形参）调用方法
		
		self.assertIn('english',my_survey.responses)
		#断言进行匹配
		
		
	def test_store_three_responses(self):
		question="what language did you learn first?"
		#survey的属性
		my_survey=AnonymousSurvey(question)
		#形成实例
		responses=['english','spanish','mandarin']
		#survey的另一个属性，一个不为空的测试用列表
		for response in responses:
			my_survey.store_response(response)
		#对测试列表中的每个元素调用survey中的方法store_response(元素)
		#调用后应该形成了一个试后列表
			
		for response in responses:
			self.assertIn(response,my_survey.responses)
		#对测试列表中的每个元素进行循环，检测它们是否在试后列表中
		#my_survey.responses就是前面survey中的self.responses
			
unittest.main()
