I'm creating a TemporaryFolder using the @Rule annotation in JUnit 4.7. I've tried to create a new folder that is a child of the temp folder using tempFolder.newFolder("someFolder") in the @Before (setup) method of my test. It seems as though the temporary folder gets initialized after the setup method runs, meaning I can't use the temporary folder in the setup method. Is this correct (and predictable) behavior?
This is a problem in Junit 4.7. If you upgrade a newer Junit (for example 4.8.1) all @Rule will have been run when you enter the @Before method:s. A related bug report is this: https://github.com/junit-team/junit4/issues/79
