python如何测试程序

#coding=utf-8

import unittest

from name_function import get_formatted_name

class NamesTestCase(unittest.TestCase):

    def test_first_last_name(self):

        formatted_name=get_formatted_name('janis','joplin')

        self.assertEqual(formatted_name,'Janis Joplin')

    def test_first_last_middle_name(self):

        formatted_name=get_formatted_name('wolfgang','mozart','amadeus')

        self.assertEqual(formatted_name,'Wolfgang Amadeus Mozart')

#注意下面这行代码，不写会报错哦~~~书中没有这行

if __name__=="__main__":

    unittest.main()

unittest.main()

if __name__=="__main__":
