Yes, but that is the required test to assure that your transponder is sending the altitude that is being reported by your Altitude indicator in your aircraft.
If you are buying a transponder, and do not have an aircraft to use it in, I strongly suggest that you wait until you are ready to install it in your aircraft. They will only get less expensive over time.

In my area there is a guy who travels from airport to airport and performs this service for a fee of $75. We get a notice from our FBO when he will be here and we all make the appointments if needed.
