It's the only way to prove the one you've got is good or bad.
Borrow one. The dealer's/shops generally have access to new ones they can drop in to see if it works.
I all but gave up on my 87 doing this and finally disassembled the IAC motor/valve to examine it. The three-segment commutator was burnt by the two copper rods that serve as brushes..not a very good 'motor' if you look at permanent magnet motors with graphite brushes. At that point a new IAC unit was installed and the idle issues went away.
