在执行测试用例时，有时候有些用例是不需要执行的，那我们怎么办呢？难道删除这些用例？那下次执行时如果又需要执行这些用例时，又把它补回来？这样操作就太麻烦了。
unittest提供了一些跳过指定用例的方法
- @unittest.skip(reason)：强制跳转。reason是跳转原因
- @unittest.skipIf(condition, reason)：condition为True的时候跳转
- @unittest.skipUnless(condition, reason)：condition为False的时候跳转
- @unittest.expectedFailure：如果test失败了，这个test不计入失败的case数目
