Man, I'm going to catch it for that title. Okay, let me get this out up front: this post is a hypothesis that I consider probable. That's why there's a question mark in the inflammatory title. Okay, asbestos underwear in place, let's continue.
Here's the logic flow for my hypothesis.
Unit testing (and its bosom buddy automated testing) provides substantial benefits when used regularly. These benefits are well-understood.
Ensuring or regularizing unit testing is the primary value proposition of Test-driven Development (TDD).
A majority of vocal unit testing...
One of the things that irks me when discussing certain technical topics is a tendency towards boosterism that can hinder, or even halt, deeper evaluation and discussion. Some topics, tools, or practices arrive with a divine imprimatur of authority that is hard to resist. Since I believe in being personally responsible for the software development I undertake, I sometimes find myself exploring murky territory that seems like it should be better mapped. The latest of these pre-hallowed principles is Test-driven Development.
What comes across as a casual assumption of superiority gets my hackles up. I'll show what I mean using...
Because Unit Testing is the plain-Jane progenitor of Test Driven Development, it's kind of unfair that it doesn't have an acronym of its own. After all, it's hard to get programmer types to pay attention if they don't have some obscure jargon to bandy about. UT is too awkward, besides being a state abbreviation in the U.S., so for this post (and, if it catches on, future posts as well) I'll borrow from the telco folks and call unit testing Plain Old Unit Testing.
The Best of all Possible Worlds
Part of my problem with TDD has been that it claims...
The discussion spawned from my TDD post has been interesting to me. I've enjoyed the comments by Phil on his post and by him and others on my own. I'm particularly flattered that one of the authors of the original study dropped by. I disagree with some of his points, but this isn't where I want to address them. Instead, I want to examine the discussion itself because this is definitely something that we as a software development community could be better at.
First, I want to emphasize something that I could have made clearer in my original post....
One of the most useful classes I took in college was an introductory statistics class that was intended to discourage Poli. Sci. majors from continuing in their course of study (I was one at the time). The interesting thing about the class is that it included study and analysis of research as a core part of the class. We learned how to put a study together, how to develop controls, and different formulas used to confirm whether we had statistically significant results or not.
So when Phil Haack announced that Research Supports the Effectiveness of TDD I was more than...
I can’t believe the potent response I’ve gotten on my posts about Dependency Injection. Ayende Rahien responded individually to each of my posts himself, which is more than a little bit intimidating all on its own and a couple of development heavyweights left comments directly. Nate describes Ayende’s posts as the cavalry arriving and links to a couple of other responses. All of these posts disagree with me, though a post by Aaron Jensen indicates that he’s at least willing to consider the possibilities.
All of this should have been foreseeable, really, as soon as I decided to publicly post...
