python自带的单元测试模块

unittest doctest

test_list.py

# -*- coding: utf-8 -*-import unittestclass TestList(unittest.TestCase):    def setUp(self):        self.c_list = range(5)        print("setup test module")    def tearDown(self):        del self.c_list        print("teardown test module")    def test_equal(self):        print("test equal")        c = self.c_list        self.assertEqual(c, [0,1,2,3,4])    def test_in(self):        print("test in")        c = self.c_list        self.assertIn(1, c)if __name__ == "__main__":    unittest.main()

每个以test开头的method都会被调用，调用之前会调用setUp方法，之后会调用tearDown方法

test_with_suit

# -*- coding: utf-8 -*-import unittestclass TestList(unittest.TestCase):    def setUp(self):        self.c_list = range(5)        print("setup test module")    def tearDown(self):        del self.c_list        print("teardown test module")    def test_equal(self):        print("test equal")        c = self.c_list        self.assertEqual(c, [0,1,2,3,4])    def test_in(self):        print("test in")        c = self.c_list        self.assertIn(1, c)if __name__ == "__main__":    suite = unittest.TestSuite()    suite.addTest(TestList("test_equal"))      suite.addTest(TestList("test_in"))    runner = unittest.TextTestRunner(verbosity=2)    runner.run(suite)

使用TestSuite,可以让测试更细化,将需要测试的method放入suite中

test_skip.py

# -*- coding: utf-8 -*-import unittestSKIP = Falseclass TestList(unittest.TestCase):    def setUp(self):        self.c_list = range(5)        print("setup test module")    def tearDown(self):        del self.c_list        print("teardown test module")    @unittest.skip("skip this test")    def test_equal(self):        print("test equal")        c = self.c_list        self.assertEqual(c, [0,1,2,3,4])    @unittest.skipIf(SKIP==True, "skip this test with if")    def test_in(self):        print("test in")        c = self.c_list        self.assertIn(1, c)if __name__ == "__main__":    unittest.main()

可以让某个测试方法直接跳过，或者使用@unittestskipIf,@unittest.skipUnless装饰器,控制测试的数量

test_doc.py

# -*- coding: utf-8 -*-def double(num):    """ This function calculate positive integer square value.    Example:        >>> double(10)        100        >>> double(-1)        Traceback (most recent call last):        ...        ValueError: the num must is positive integer    """    if num < 0:        raise ValueError('the num must is positive integer')    return num**2if __name__ == "__main__":    import doctest    doctest.testmod()

如果没有输出，就说明是测试时正确的
