Sheer insanity. Mary is a moron and her app users are prime targets for hackers.<p>Just because the test coverage passes, doesn't mean the code doesn't do something nefarious behind the scenes.<p>If Mary doesn't review the code before release, she deserves the rapture her customers will bestow upon her when she finds out Josh was paid by a competitor to decimate her business.<p>It's not that I believe people are inherently evil, I just believe that you need to review every patch to make sure it does what it's supposed to do and <i>no more</i>.
