I suspect you are missing some context here.

Cedric wrote the book on unit testing (literally! [1]). He uses PHP at times when he doesn't need the reliability unit testing gives you and can't justify the extra time it takes.

Given that he works at Google, I suspect his "in production" doesn't actually mean big, real sites.

I'm less astonished at his lack of unit testing (because I often eschew it in PHP projects, too) and more the, uh, everything else that he said that was horrible.

And I don't care if it's a "big, real" site or not, making mods to a live site is (almost) never good practice. Fix it offline, test it, push.
