I find it easy to fall into the trap of wondering, how is it so many people can misunderstand testing. Sure, it’s a broad subject and there are far too many (wrong) opinions on the subject. But then, it’s easy to forget how I was also so very wrong not that many years ago. I too, thought of tests as an optional extra, afforded only to the lucky few, not those of us slogging it out in the pits of legacy code, or those of us rushing releases for a new startup.
