unittest 中用于跳过 test method, test class,的相关装饰器

可以使用unitest.skip装饰器族跳过test method或者test class,这些装饰器包括:
① @unittest.skip(reason):无条件跳过测试，reason描述为什么跳过测试
② @unittest.skipif(conditition,reason):condititon为true时跳过测试
③ @unittest.skipunless(condition,reason):condition不是true时跳过测试

class MyTestCase(unittest.TestCase):  @unittest.skip("demonstrating skipping")  def test_nothing(self):    self.fail("shouldn't happen")  @unittest.skipIf(mylib.__version__ < (1, 3),           "not supported in this library version")  def test_format(self):    # Tests that work for only a certain version of the library.    pass  @unittest.skipUnless(sys.platform.startswith("win"), "requires Windows")  def test_windows_support(self):    # windows specific testing code    [e-mail]("showing class skipping")class MySkippedTestCase(unittest.TestCase):  def test_not_run(self):    pass
