"Don't put loops in your tests" the advice goes. While there are times when a small for loop might be useful, for gosh sakes, don't use a do..while loop.

And please don't ask me what triggered this post.

p.s. Your for loop might also be hiding a deficiency in your test, aka a Test Smell. Might be fine, but worth a little more attention.

SwiftUI TDD (Part 1): Writing Your First Failing Test

Uso #ExtremeProgramming da quando facevo #debugging all'università, oltre 20 anni fa.

Una cosa non cambia: scrivere codice è facile, definirne tutto il comportamento no.

🎤 A #PyConIT 2026 porterò un #workshop su #Python 🐍 e #TDD:
dalle variabili al primo test, per chiarire cosa il software debba fare prima di implementarlo.

Hello! #introduction

I just migrated from https://hachyderm.io/@mattwynne which was 👍🏻, but I have been meaning to move over here for some time because I love the initiative to democratically run our social media!

I'm from the UK originally, now based in Nelson, BC.

I'm a generalist/polyglot programmer. I lead the https://github.com/cucumber #opensource project and I'm known for coaching teams in technical practices like #TDD/#BDD and #EnsembleProgramming.

Also #SkiTouring and generally #MountainLiving

In Test-Driven Development (#TDD), a RED test is only part of the story. Just because a test fails, doesn't mean that you're ready to write code to make it GREEN. Before you write that code, check that the test fails as it is SUPPOSED to fail.

Another stream, another set of notes. So much "new"!

I try out a new design for Projectors, splitting EventConsumer into two pieces. Test-driving shows how it's about design exploration, not just writing tests.

Back to streaming, with notes from yesterday's stream: https://ted.dev/articles/2026/03/23/live-coding-journal-mar-23-2026/

I chatted about consistency boundaries, missing-event heuristics, and encoding (serializing) events.

Finding a failing test 🚨, coming back from the ☕️ break, feels just so ✅ .

- I know where I left off
- I know what to continue with
- I get back into the flow within seconds
- no need to search and analyze the git history
- it 💡 enlightens me and lets me continue where i left off

also when doing hashtag#PHP 😎

In fact, tooling hasn’t ever made much of an impact in these areas at all, especially compared to disciplined practice on the part of collaborative knowledge workers. That’s why we’ve invented #UCD, #agile, #TDD... all of these are habits of complexity-tending, and they’re what disposes systems toward producing value, if anything does. 6/7 #AI #software

Developers often see TDD primarily as a testing technique, missing its potential to guide design. @davefarley77 talk showed how shifting focus allows TDD to actively shape software architecture and foster better code structure. It's about using TDD to drive design, not just validate it.

On Monday's live coding #Java stream, I finished the UI for "Reschedule Concert". I cheated a bit and reused some existing screens, but hey, this is an example/learning app (despite its ever-increasing scope!).

I also compare my "Olive" #TDD Tests with Kent Beck's Test List.

Tempted to get a couple of new cards printed to put into my #TDD Game (https://tdd.cards):

"LLM Wrote Too Much Code" and "LLM Wrote Your Tests"

These would both be "negative" cards in the game. The way to "resolve" those cards would be a "Refactoring" card, or a "Revert".

In fact, I got so into the flow writing the notes that I missed my normal dinner time!

You can catch up on the notes (#EventSourcing, #Java, #TDD) so far:

And catch me live (Mon-Thu, 8pm UTC) at https://jitterted.stream/

It's here! I hold in my hand @RobMyers's new book "Essential Test-Driven Development"!

A long time coming, but thrilled for Rob that it's finally out into the world!

Essential Test-Driven Development is now available in print on this site:

https://www.informit.com/store/essential-test-driven-development-9780134494159

The eBook should be available there soon. The print edition will also be available from other retailers (Amazon, etc.) in a couple weeks.

If you like the book, please give it a positive review on Amazon (regardless of where you purchase it...The Algorithm, y'know! 😉).

“#TDD and #BDD aren’t really about testing at all. They’re about feedback loops and thinking clearly about intent before implementation.”

Intent first!
