The Correlation Premise: Redux

Geekery, TDD / September 23, 2018

This entry is part [part not set] of 9 in the series Underplayed Premises

My five TDD premises stuff has been well-received over the months since I put it out, but one of them seems still very underplayed, even by many died-in-the-wool TDD’ers: the correlation premise. The correlation premise says that the internal quality of our code correlates directly with our productivity. When the internal quality goes up, productivity […]

TDD Pro-Tip: Start Builders & Partial Comparators Early

Geekery, TDD, Pro-Tip / September 21, 2018

TDD Pro-Tip: Prevent complex test data from spiraling out of control by going to builder & custom comparator early on. The push-to-small, coupled with SOLID, coupled with things like third normal form, all lead us to a place of wanting to compose domain objects into potentially very rich dependency graphs. A card in a address-tracking

Acculturation: A Little Deeper

Coaching, Geekery / September 18, 2018

I’ve mentioned "acculturation" a couple of times lately. Let’s dig in a little deeper on that. In our trade, we make much of "education", training and learning and skills inventories and such-like.

Geekery, TDD, Pro-Tip / September 14, 2018

TDD Pro-Tip: "No, smaller." In TDD, almost without exception, we want everything: a test, a method, a class, a step, a file, really, almost everything, to be as small as it can be and still add value to what we’re doing. This is the most common gaping hole in the practice of the noob, and

TDD Pro-Tip: TDD & Refactoring Are Intertwined Life-Game

Geekery, TDD, Pro-Tip / September 8, 2018

TDD Pro-Tip: TDD and refactoring are permanently intertwined activities, neither of which can be grasped all at once, so start learning how to write tests at the same time you’re learning how to change code w/o adding bugs to it. Some activities are what I think of as "life games". The better you get at

TDD Pro-Tip: They Work For You, Not You For Them

Geekery, TDD, Pro-Tip / September 4, 2018

TDD Pro-Tip: remember who works for who, and shape your tools to your hand, not your hand to your tools. (Btw, these tips are in no particular order. If you want to know the truth, i’m musing them as I do them. People always know more than they can say, and i’m no exception, but
