1. unittest.TestCase类中的常用的断言方法

1.1 子测试：记录错误并测试完所有的代码

class DemoTest(unittest.TestCase):    def test_subtest(self):        for i in range(5):            with self.subTest(name=i):  # 子测试参数用于输出                self.assertEqual(i % 2, 0)>>>(djProj_py3) appledeMacBook-Air-7:tests apple$ python -m unittest test_a.DemoTest.test_subtest======================================================================FAIL: test_subtest (test_a.DemoTest) (name=1)----------------------------------------------------------------------Traceback (most recent call last):  File "/Users/apple/PycharmProjects/work/practice/tests/test_a.py", line 19, in test_subtest    self.assertEqual(i % 2, 0)AssertionError: 1 != 0======================================================================FAIL: test_subtest (test_a.DemoTest) (name=3)----------------------------------------------------------------------Traceback (most recent call last):  File "/Users/apple/PycharmProjects/work/practice/tests/test_a.py", line 19, in test_subtest    self.assertEqual(i % 2, 0)AssertionError: 1 != 0----------------------------------------------------------------------Ran 1 test in 0.000sFAILED (failures=2)

1.2测试套件：将多个用例或套件的实例组合起来，完成产品功能组级别的测试。

分别为每个参与测试方法创建实例，并加入套件。

class UserTest(unittest.TestCase):    def test_user(self):        self.assertTrue(True)  # 判断是否为真class CartTest(unittest.TestCase):    def test_cart(self):        self.assertFalse(False)suite = unittest.TestSuite()suite.addTests((UserTest(‘test_user‘),  # 创建实例并加入套件suite               CartTest(‘test_cart‘),)               )unittest.TextTestRunner(verbosity=2).run(suite)
# code end!! >>>(djProj_py3) appledeMacBook-Air-7:tests apple$ python test_a.py test_user (__main__.UserTest) ... oktest_cart (__main__.CartTest) ... ok----------------------------------------------------------------------Ran 2 tests in 0.000sOK

批量测试单个用例，可通过重写runTest

class TestDamo(unittest.TestCase):    def add(self):        self.assertTrue(1)    def add1(self):        self.assertFalse(‘‘)    def runTest(self):        tests = (self.add, self.add1)        for test in tests:            with self.subTest(t=test):                test()>>>(djProj_py3) appledeMacBook-Air-7:tests apple$ python -m unittest -v test_a.py runTest (test_a.TestDamo) ... ok----------------------------------------------------------------------Ran 1 test in 0.000sOK
