@desc:學習unittest的用法
注意setUp/setUpClass，tearDown/tearDownClass的區別
① setUp():每個測試函數運行前運行
② tearDown():每個測試函數運行完后執行
③ setUpClass():必須使用@classmethod 裝飾器,所有test運行前運行一次
④ tearDownClass():必須使用@classmethod裝飾器,所有test運行完后運行一次unittest還有一些不常用的裝飾器：
@unittest.skip(reason):無條件跳過測試，reason描述為什么跳過測試
@unittest.skipif(conditition,reason):condititon為true時跳過測試
@unittest.skipunless(condition,reason):condition不是true時跳過測試
@unittest.expectedFailure:如果test失敗了，這個test不計入失敗的case數目
