The simplest test possible is to submit a job that simply runs the "set" command, which does nothing but print out the operating system's environment variables. You can see what it's expected to do by opening a cmd prompt on Windows or a Terminal on OS X and simply typing set and hitting <Enter>.
Start the WranglerView, and find the Test->Qube Test (Set) job
Then, just click "Submit":
Go to the Job view in the WranglerView, and select the job (it will be named "Qube Test (set) job"). Click the "Refresh" button, and you should see the job in a "Complete" state.
