#1.城市和国家:编写一个函数,它接受两个形参:一个城市名和一个国家名。 #这个函数返回一个格式为City,Country的字符串,如Santiago,Chile。将这个函数 #存储在一个名为city_function.py的模块中 #创建一个名为test_cities.py的程序,对编写的函数进行测试 #编写一个名为test_city_country()的方法核实得到的字符串正确 #city_function.py def city_country(city,country): #国家和城市 country_city = city + " " + country return country_city.title() #test_cities.py from city_function import city_country print(" Enter q to quit.") while True: #输入城市和国家 city = input(" Enter a city: ") if city == 'q': break country = input(" Enter country of the city: ") if country == 'q': break get_msg = city_country(city,country) print("The city and country: " + get_msg.title()) #unittest_test_city.py import unittest from city_function import city_country class CityTestCase(unittest.TestCase): def test_city_country(self): get_city_country_name = city_country("beijing","china") self.assertEqual(get_city_country_name,"Beijing China") unittest.main() #2.人口数量:修改1中的函数,使其包含必不可少的形参population #并返回一个格式City,Country - population xxx 的字符串 def city_country(city,country,population=''): #国家和城市 country_city = city + ", " + country + " -- Population " + population return country_city.title() ##测试模块 import unittest from city_function import city_country class CityTestCase(unittest.TestCase): def test_city_country(self): get_city_country_name = city_country("beijing","china","5000") self.assertEqual(get_city_country_name,"Beijing, China -- Population 5000") unittest.main()
#3.雇员:编写一个名为Employee的类,其方法__init__()接受名、姓和年薪 #并将它们存储在属性中。编写一个名为give_raise()的方法,它默认将年薪增加5000 #但也能够接受其他的年薪增量。编写一个测试用例,其中包含两个测试方法: #test_give_default_raise()和test_give_custom_raise() #使用setUp方法,以免在每个测试方法中都创建新的雇员实例,运行这个测试用例 #确认两个测试都通过 #employee.py class Employee(): def __init__(self,first_name,last_name,salary): self.first_name = first_name self.last_name = last_name self.salary = salary self.raising = 5000 def give_raise(self): return self.raising #test_employee.py import unittest from employee import Employee class TestEmployee(unittest.TestCase): #针对Employee类的测试 def setUp(self): self.employee_test = Employee('Ma','Naoke',5000) def test_give_default_raise(self): #测试默认的工资 raising = self.employee_test.give_raise() self.assertEqual(raising,5000) def test_give_custom_raise(self): #测试年薪增量 self.employee_test.raising = 6000 raising = self.employee_test.give_raise() self.assertEqual(raising,6000) unittest.main()
