| 方法 | 用途 |
|---|---|
| assertEqual(a, b) | 核实 a == b |
| assertNotEqual(a, b) | 核实 a != b |
| assertTrue(x) | 核实 x 为True |
| assertFalse(x) | 核实 x 为False |
| assertIn(item, list) | 核实item在list中 |
| assertNotIn(item, list) | 核实item不在list中 |
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 0.000s FAILED (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) ... ok test_cart (__main__.CartTest) ... ok ---------------------------------------------------------------------- Ran 2 tests in 0.000s OK
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 0.000s OK
