Won't hurt to run the test yourself. I ran mine a few times after having mine replaced, just for piece of mind. Drove to work with the test running so I could keep an eye on it. Turn on the lights, radio, seat warmers, heater/AC...and anything else that will add to the load.
I actually had to have mine replaced twice. The first one would stop charging after the car got warm and the motor got over 5k rpm. Turned out to be a bad "new" unit. Indy replaced again and all has been great since.
Just monitor it for a bit, better to be safe and save your new battery.
