You can test it your self. Start the car might be pain in butt if alternator is really dead if so let car sit for a little while and charge it self up. Also you can knock on alternator with a happer bunch of dust will fall out and it will get you enough time to drive for few day to go get new alternator and install it without car breaking down. Anyways start the car, then disconnect the negative wire on the car if it dies the alternator is dead if not then alternator is good.

How can I test my alternator to see if it is discharging my battery?
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.
