I might just not be very good at this programming thing, but to me these kinds of articles on testing often (not always) remind me of my annoying tendency to implement a comprehensive productivity approach (often combined with buying yet another task app) that, on paper, really should help me keep track of my life. Usually it's a variation on Getting Things Done, which stands out in its exhaustive, all-encompassing, fine-grained approach. In practice the whole falls apart after a week or so because I forget to do things the right way or because I don't feel like processing my 'inbox'... Instead, I seem most effective when I write down my top three tasks of the day on a piece of paper. Maybe I get that feeling because I've mostly experienced companies where testing didn't really seem to have much of an effect. Whenever I asked about this lack of efficacy, the answer was usually "that's because we're not implementing it completely!" Which is exactly what I hear (and suggest) whenever I or someone else falls off the GTD wagon. Am I completely wrong about that feeling? I mean that as an honest question, as I truly don't want to be negative and I'm way to inexperienced to be cynical about these things :-).
