Are you in California?
It sounds like your mechanic is referring to the vehicle not being ready for the test. That is a failure in many jurisdictions. It does happen if the battery was disconnected. After that the car has to run through a sequence of self-diagnostics - if the sequence is completed then the car is "ready" for the test, and if all the diagnostics show ok at test time then you pass. It takes some varied driving cycles and some time - different in different cars - for the car to be ready, so the usual advice is to drive the car for a couple of weeks, then get tested.
I don't think there is any way for the dealer or anyone else to preset the system to become ready - other than by driving the car.
