I would bring your car in, have a service advisor walk with you to the car, start up the engine, and turn on EVERY SINGLE accessory you possibly can. I noticed that when my alternator was going out, the red light would come on as soon as I turned on my headlights, and then turn off after driving with them off. SO if you're planning on having the battery light illuminate when you get to the dealer, drive there with your headlights on, radio on, rear window defroster, whatever else to make that alternator light go on so you can have them replace it out for you.
I dont think there's any test you can tell them to perform... It would almost be like telling someone how to do their job, and I dont think they would take it too well.
