Why are the `all_read` and `all_write` bits implementation details that shouldn't be tested when the lack of `all_exe` is? This test is for testing `writeToOutput`. Part of `writeToOutput`'s behaviour appears to be to create a file with the `all_read` and `all_write` bits set. Therefore, we should be testing that behaviour. As there was already one issue with the permission bits of the file this method creates, and you are directly modifiyng a test to add permissions testing, I think it's justified to request testing of the other bits.
