跳过测试和预期失败

概要

• unittest.skip() 直接跳过测试
• unittest.skipIf() 条件为真，跳过测试
• unittest.skipUnless 条件为假，跳过测试
• unittest.expectedFailure 预期设置失败

import unittest


class Test1(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        print('setUpClass')
        print()
    def setUp(self):
        print("Test1 start")

    #条件为真，跳过测试
    # @unittest.skipIf(4 > 3, "skip Test_c")
    def test_c(self):
        print("test_c")

    # 条件为假，跳过测试
    # @unittest.skipUnless(1<0, "skip test_b")
    def test_b(self):
        print("test_b")

    def tearDown(self):
        print("Test1 end")
    @classmethod
    def tearDownClass(cls):
        print('tearDownClass')

# 跳过Test2测试类 将不会被执行
@unittest.skip(" skip Test_2")
class Test2(unittest.TestCase):
    def setUp(self):
        print("Test2 start")

    def test_d(self):
        print("test_d")

     # 预期设置失败
    @unittest.expectedFailure
    def test_a(self):
       print("test_a")

    def tearDown(self):
        print("Test2 end!")


if __name__ == '__main__':
    unittest.main()

输出结果：

setUpClass
Test1 start
test_b
Test1 end
Test1 start
test_c
Test1 end
tearDownClass
