it takes a set number of drive cycles to set a MIL for the precats, you must not have passed that point before the emissions test, the CEL will turn on in time
edit: what year do you have? if it is a 95 you will not get a precat code as there are not sensors to monitor the pre-cats, also the main cat is good enough to past emision testing where they sample the exhaust if the car is nice and warmed up
