What can I do to get it to complete?

Alternatively as a last resort, is there a hack to trick or reflash the computer to think it's tested? I've absolutely had it after getting it inspected 3 times now, driving it in multiple scenarios, and letting it idle in hopes the self test will occur yet it never does... and to top it off, doing all this without plates/registration. I can't register unless I drive it more. A catch 22 I'm tired of being in.

It doesn't say failed... just 'Not Completed'.


UPDATE:

Drove more and tested at O-Reilly's (their tester reads and clears emissions info on this car). Still not ready. Drove more and tested again... this time with the Harbor Freight Zurich ZR4 tester ($39.99 and surprisingly it works!) and readiness for EGR system now complete. NOTE!! Do NOT clear codes... it will make the car run the Readiness monitors again which takes time.
