If that is the case that is a very old program. Usually the bare minimum is check the status AND that the OBDII system has cycled through all the checks and is "ready".
Otherwise you can just reset the check engine light in the parking lot of the smog station and pass before the computer gets through all the test cycles.
(I got REAL familiar with running the test cycle when I was fighting with the evaporative emission system in my Astro Van.
