11-1 城市和国家：

'''module city_functions.py'''

def city_country(city, country):
	return str(city) + ", " + str(country)

'''文件名： test_cities.py'''
import unittest
from city_functions import city_country

class CityCountryTest(unittest.TestCase):
	def test_city_country(self):
		formatted_name = city_country('Santiago', 'Chile')
		self.assertEqual(formatted_name, 'Santiago, Chile')
		
				
unittest.main()

运行结果：

11-2 人口数量：

'''module city_functions.py'''

def city_country(city, country, population=5000000):
	return str(city) + ", " + str(country) + " - population " + str(population)

'''文件名： test_cities.py'''
import unittest
from city_functions import city_country

class CityCountryTest(unittest.TestCase):
	def test_city_country(self):
		formatted_name = city_country('Santiago', 'Chile')
		self.assertEqual(formatted_name, 'Santiago, Chile - population 5000000')
		
	def test_city_country_population(self):
		formatted_name = city_country('Santiago', 'Chile', 5000000)
		self.assertEqual(formatted_name, 'Santiago, Chile - population 5000000')
		
				
unittest.main()

运行结果：

11-3 雇员：

class Employee():
	def __init__(self, last_name, first_name, salary):
		self.last_name = last_name
		self.first_name =first_name
		self.salary = salary
		
	def give_raise(self, count=5000):
		self.salary += count

'''文件名： test_employee.py'''
import unittest 
from employee import Employee

class TestEmployee(unittest.TestCase):
	def test_give_default_raise(self):
		formatted = Employee('dong', 'zhiqi', 10000)
		formatted.give_raise()
		self.assertEqual(formatted.salary, 15000)
		
	def test_give_custom_raise(self):
		formatted = Employee('dong', 'zhiqi', 10000)
		formatted.give_raise(10000)
		self.assertEqual(formatted.salary, 20000)
		

unittest.main()

运行结果：
