Who tested the Coke vending machine?

 
 

My good ol', thrill seeking, programming, secret harboring, friend Matt blogged about a bug in a Coke vending machine that will get you 2 cokes for the price of 1. From a quality assurance perspective this is really quite interesting...well at least it is to me because I've been in more of a software quality assurance world for most of my career and hadn't really thought about porting my hacker mentality to physical or mechanical devices in the "real" world. It's Quality Assurance and testing on a different plane but the same concepts still apply. Interesting...

Do you think the creator of this vending machine actually went through an official testing process?

Now that I think about it, I think my first memory of lack of testing on this plane was when I was about 6 years old. I remember going to the grocery store with my babysitter and her son (who was about 13) would play the Asteroids arcade game that sat by the exit door using filed down metal washers instead of quarters. Pure genius... I wonder what he's doing now? I wonder if he's in QA?
