My TDD Analogy
Posted on June 3rd, 2009
In my post about Test Driven Design I expressed concerns around building your entire architecture to just support testing. My thoughts were definately tough to put into words, maybe I should have used more pictures :)
I do finally feel I have a decent analogy to the problem I’m concerned with. Building your application to be perfectly testable would be like building a car to always pass a crash test and to say – “let’s build a car that could never ever hurt someone”. Great, so it has no wheels or even an engine but dammit, it performs great in crash tests, it passes every test!
Applications have to work, testing like vehicle safety does unfortunately come second to functionality. Should you test? of course – but it is a balancing act so don’t get sucked into all the hype.
Also, in the words of Jeff Atwood, don’t just listen to me or don’t listen to me at all. I am no expert so do your homework :)
