        **This has to sleep as it can take a couple seconds for the job to start**
        Setting it lower will cause issues, you have to consider the Start-Job has to load the module which takes on average 3-4 seconds itself before it executes the command.

        If someone knows a cleaner method by all means adjust this test.
