直接上代码:
__author__ = 'zc' import unittest class demoSkipTest(unittest.TestCase): a = 70 b = 50 print(a%b) def test_add(self): """加法""" result = self.a + self.b self.assertEqual(result, 40) def test_add_2(self): self.skipTest("强制跳过示例") result = self.a + self.b self.assertEqual(result, 9) @unittest.skipIf(a > b, u"a>b,正确就强制跳过") def test_sub(self): """减法""" result = self.a - self.b self.assertTrue(result == -30) @unittest.skipUnless(a%b == 2, u"错误就跳过") def test_div(self): """除法""" result = self.a / self.b self.assertTrue(result == 1) @unittest.expectedFailure def test_mul01(self): """乘法""" result = self.a * self.b self.assertTrue(result == 350) @unittest.expectedFailure def test_mul02(self): """乘法""" result = self.a * self.b self.assertTrue(result == 3500) if __name__ == "__main__": unittest.main()
运行结果:
Fssxus ====================================================================== FAIL: test_add (__main__.demoSkipTest) 加法 ---------------------------------------------------------------------- Traceback (most recent call last): File "/xxx/run_safe_test.py", line 24, in test_add self.assertEqual(result, 40) AssertionError: 120 != 40 ---------------------------------------------------------------------- Ran 6 tests in 0.000s FAILED (failures=1, skipped=3, expected failures=1, unexpected successes=1)
说明:
最后两个,先预想这个用例是错误的,但是最后一个结果是正确的,所以
expected failures=1 (预想就是错的)
unexpected successes=1 (没想到是正确的)
序号 | 方法 | 说明 |
1 | unittest.skip(reason) | 强制跳转。reason是跳转原因 |
2 | unittest.skipIf(condition, reason) | 条件跳转,如果condition是True则跳转 |
3 | unittest.skipUnless(condition, reason) | 除非conditioin为True,才进行调整 |
4 | unittest.expectedFailure() | 标记该测试预期为失败 ,如果该测试方法运行失败,则该测试不算做失败 |
