@desc:学习unittest的用法
注意setUp/setUpClass，tearDown/tearDownClass的区别
① setUp():每个测试函数运行前运行
② tearDown():每个测试函数运行完后执行
③ setUpClass():必须使用@classmethod 装饰器,所有test运行前运行一次
④ tearDownClass():必须使用@classmethod装饰器,所有test运行完后运行一次unittest还有一些不常用的装饰器：
@unittest.skip(reason):无条件跳过测试，reason描述为什么跳过测试
@unittest.skipif(conditition,reason):condititon为true时跳过测试
@unittest.skipunless(condition,reason):condition不是true时跳过测试
@unittest.expectedFailure:如果test失败了，这个test不计入失败的case数目
