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。

import unittest
class Test1(unittest.TestCase):
    def setUp(self):
        print("Test1 start")
    # @unittest.skipIf(4>3,"skip Test_d")
    def test_c(self):
        print("test_c")
    @unittest.skipUnless(1<0,"skip test_b")
    def test_b(self):
        print("test_b")

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

# @unittest.skip("skip Test_2")
class Test2(unittest.TestCase):
    def setUp(self):
        print("Test2 start")

    def test_3(self):
        print("test_3")
    @unittest.expectedFailure
