The contents of `temporaryFolder` might only have the meaning to the specific test cases and we should clean it after the test. For example `testRetrieveJobGraphWithJarInUsrLibDir` would create a directory `job` and add some files to this directory for a specific scenario. However other tests might not need these content. That is why I use `temporaryFolder` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
