I would think it will take longer than 10 mins just to drain the oil, but then maybe not, I got mine done at 7400miles (not at the $tealer and I paid for it) and it took them about 40 mins. They do have to run the engine for a while because these new engines don't have dipstick, so they have to let the engine pump the oil through it's entrails and then if needed add more. If they did a test drive, I am guessing they were checking for that.
