They do the VIN matching, then they hook your car up to a machine that reads hydrocarbons, carbon dioxide and oxides of oxygen or some other shit, basically most Fuel Injected Honda's will pass that part. Then they pop your hood and make sure you have your vacuum/charcoal canister hooked up to SOMETHING, they really don't care where all the Vacuum's go, as long as you passed the first part and everything is hooked up. They will SOMETIMES fail you for a check engine light turning on. This only applies to cars before 1996, if you have 1996+ they just plug it in. Depending on which Emissions place you go to, they're supposed to check to make sure you have a catalytic converter on the car. My b16 95 coupe passed with flying colors with a cat, and I'm sure it would've still passed without one. They didn't check for my cat, but I didn't want to risk it.
Also, if you plan to re-title your car in AZ, you will have to go through a Level 1 inspection, which consists of Blinkers/Lights/Horn/Seatbelts and both front doors open and close, sometimes they check for the hood latching also.
