python单元测试框架-unittest（五）之跳过测试和预期失败

概要

• @unittest.skip(reason): skip(reason)装饰器：直接跳过测试，并说明跳过测试的原因。
• @unittest.skipIf(reason): skipIf(condition,reason)装饰器：条件为真时，跳过测试，并说明跳过测试的原因
• @unittest.skipUnless(reason): skipUnless(condition,reason)装饰器：条件为假时，跳过测试，并说明跳过测试的原因
• @unittest.expectedFailure(): expectedFailure()测试标记为失败。

     def test_b(self):
         print("test_b")

     def tearDown(self):
         print("test end")

 # @unittest.skip("skip Test_2")
