TDD (Meta) Pro-Tip: Grasp the judgment premise by the horns and do not let it go, in every single one of these pro-tips. Here is the judgment premise, taken from Five Underplayed Premises Of TDD: "We happily rely on individual humans using their individual judgment." Imagine if there was a formulaic way to program computers. […]

TDD Pro-Tip: Wrap framework collection classes early and often. The Primitive Obsession smell is ubiquitous around collections, and not seeing and fixing it can greatly hamper productivity. In HollywoodSimulator, a common act of every Person is to spend time manipulating their little black book — the collection of the contacts they have. The first-pass way

TDD Pro-Tip: Because the power of TDD is operational rather than artifactual, test-before provides several benefits over test-after. Sometimes folks propose the writing of tests after the code is written. The idea here is that the point of the game is to have the tests, and that it makes no difference whether we do them

TDD Pro-Tip: TDD depends heavily on a view that accepts and even values iteration. TDD is an I&I style of work: iteration and increment are both involved. Nearly everyone gets "increment": an increment is an improvement, an enhancement, a detectable step forward in value. Each increment is a pass over the code, during which we

Seen a few soft murmurings about the idea that the made, the making, and the maker includes the made-for. That’s good. If the idea doesn’t work, let’s change it so it does. I do want to toss some grist into the mill that might have impact. In some of what i’m seeing, "children" could easily

A formulation I’m trying out today: "my agility is an autopoietic community centered around the triple balancing of the made, the making, and the makers." there’s odd terms in it, and also missing ones, so I feel like pushing it around a little out loud. Obviously, the least ordinary term there is the a-word. Autopoeisis

There’s an old joke: A policeman comes across a drunk crawling around under a streetlamp, asks him what’s up. Drunk says he lost his car keys. So the cop helps him look for a while. But no luck, so the cop asks him, "Where’s your car, sir?" and the guy points off in the dark.

TDD Pro-Tip: The first step past beginner-TDD lies in grasping the difference between awkward and graceful collaborations, and learning the myriad contextualized patterns for moving from the former to the latter. Folks invest a little in TDD, maybe cuz they’re excited, maybe cuz they’re ordered. They read a little. They try an exercise or two.

Folks worry a lot about building the wrong thing, that is, making software that does not please the many and different interests of the org, the users, the operators. I’ve certainly seen that. We all have. Government seems particularly consistent at doing it, tho surely there are plenty of commercial orgs that have the same

TDD Pro-Tip: Build cells — logic nucleus on the inside, environment inputs & outputs on the outside, and a semi-permeable cell wall between the two. The metaphor i’m proposing here is really about the nature of borders in code. Prior to TDD, my grasp of this topic was driven largely by the great theory of
