The ultimate alternator test is to turn on all of the accessories at idle (one at a time) while watching the voltage to make sure it stays around 13V.

Headlights, high beams, fogs, blower, A/C, rear defogger, etc. With everything on at idle speed, and a voltage around 13V your charging systems is good.
