Sorry, I have to cancel today's "TDD with SwiftUI" live stream. Family obligations (good ones). Follow me on Twitch (qcoding) so you get my next go-live notification so you can join in next time as I continue exploring augmented coding using TDD.

I tell this story periodically, but it seems like it's time again: General Motors ran an automobile manufacturing plant in Fremont, California, that was one of the worst in the country. Accident rates and defects were astronomical. Absenteeism was through the roof. 1/12

Swift enumerations: How to write XCTest assertions to verify them? How do we test their associated values? Can we avoid overspecified tests? https://qualitycoding.org/unit-test-enumerations-swift/

It's been going on for decades. www.apmreports.org/episode/2019...

"Disagree and commit" is disingenuous. This is a better idea. #Teams https://werd.io/disagree-and-lets-see/

An issue we're seeing at all levels of university is that many students are simply refusing to do *anything*. They aren't reading the syllabus, aren't following assignment guidelines, aren't engaging with material, ignoring deadlines. And this might seem like old news, but it truly has ramped up.

Remember that the “Red” (failing test) part of #TDD is the perfect time to make sure the failure message is useful, instead of the less than helpful “expected actual to not be null”. #UnitTesting

The art and skills for delivering software in much more smaller incremental steps were lost with the global adoption of Pull Requests.

We get the best results from "AI" coding assistants when we: * Take small steps * Test, review and refactor continuously * Use version control to keep our code shippable * Integrate continuously * Cleanly separate concerns If only there was somewhere we could learn these skills!

Do you need code comments at all? Here are some rules of thumb for comments, with methodical refactoring steps you can take to improve your code. https://qualitycoding.org/code-comments/

Spoiler: TDD isn't one skill, it's many. I can help you build up the set of micro-skills you need to succeed with TDD… and I know many other folks who can, as well.

Instead of Pull Request code reviews, consider reviewing the code on every green light. Small diffs enables greater attention to detail, a much lower cost of fixing problems (or backing out), and there's no code review bottleneck when you want to ship. codemanship.wordpress.com/2025/11/22/w...

Where does TDD fit in the iOS ecosystem? Here's a podcast about how I depend on TDD for iOS development, and the backstory for why I do. https://qualitycoding.org/test-driven-ios-development-jon-reid/

I try not to be quite so blunt about this these days, but I stand by the overall message: you have probably been trying to go too fast. And I get it. No blame, really! If you don't have at least one impatient customer, then you have a hobby and not a business, right? :shrug:

Stop pretending SwiftUI tests are impossible — ViewInspector lets you inspect views and verify behavior. https://qualitycoding.org/viewinspector-swiftui-testing/

<rant> A periodic reminder that Sprints, Backlogs, Daily Scrums, Scrum Boards, Scrum Masters, Product Owners, Points, Velocity, PIs, etc., have NOTHING AT ALL to do with "Agile." Agility comes from working small, delivering frequently for feedback from actual customers, and adapting based on 1/3

Happy Partially Muscled Skeleton Day to all who celebrate. Be sure to let all your screams out and then disappear.

Metaphor for software development. Reminds me of a classic @jbrains.ca saying: “But test-driven development will slow us down.” J.B.: “Good.”

Many folks don't know what "refactoring" actually means, and use it to mean "rewriting". But the Refactoring book completely changed the way I code! https://qualitycoding.org/refactoring-book/

Wow. It's been so long since I was TDDing in a pre-Swift world, I'd forgotten how CRAZY FAST Objective-C was to build. The feedback is so fast, it changed things. Badmouth Objective-C all you want, but for a TDDer like me, it was a joy. https://youtu.be/NthPd0zbua4?si=-ZDlEu79gKPs4p6Z&t=1707

I sent messages to my 2 senators, and to Chuck Schumer.

Mike Johnson: ‘My Christian Faith Is More About Not Jacking Off Than Feeding The Poor’

I was laid off from Teen Vogue today along with multiple other staffers, and today is my last day. certainly more to come from me when the dust has settled more, but to my knowledge, after today, there will be no politics staffers at Teen Vogue.

This week I've restarted my live coding stream on Twitch (jitterted.stream) after a 5-month hiatus, and it's still fun! I've been working on getting the database storage of JitterTicket, the #EventSourcing example app I've been developing (and used in my recent talk).

Californians: This may be the most consequential vote of our lives. Vote YES https://www.youtube.com/watch?v=kJkPVEw55V8

I voted YES on Prop 50 because we cannot let anyone silence the will of the people. California is fighting fire with fire and standing up for democracy everywhere. Vote yes on Prop 50 by mail or in person on Election Day, this Tuesday, November 4.

That’s why the first two steps in tdd.cards are “What Should It Do?” and “How Will You Know It Did It?” #TDD

So gross, first because it excludes anyone with a spouse or kids, who don’t have those kinds of hours to give. Second, the overwhelming majority of startups fail, and most aren’t even acquired. All their effort is simply wasted. Just pointless misery.

TDD isn't about writing code first — it's about thinking first https://qualitycoding.org/describe-test-plain-english/

@ldomaradzki.bsky.social Thank you for creating xcswift! I'd like to begin contributing, if you're open to PRs. But trying to get a clean start, I'm running into obstacles: - There are 2 failing tests, both of which seem to be failing on purpose.

My "TDD with SwiftUI" live coding will be on again tomorrow at 9am Pacific (14:00 UTC). In tomorrow's session, I intend to set up a different style of augmented coding for TDD, based on what I've learned from Llewellyn Falco's amazing presentation at Craft 2025. https://www.twitch.tv/qcoding
