unittest詳解 跳過用例的執行(skip)

在執行測試用例時，有時候有些用例是不需要執行的，那我們怎么辦呢？難道刪除這些用例？那下次執行時如果又需要執行這些用例時，又把它補回來？這樣操作就太麻煩了。

unittest提供了一些跳過指定用例的方法

• @unittest.skip(reason)：強制跳轉。reason是跳轉原因
• @unittest.skipIf(condition, reason)：condition為True的時候跳轉
• @unittest.skipUnless(condition, reason)：condition為False的時候跳轉
• @unittest.expectedFailure：如果test失敗了，這個test不計入失敗的case數目
