I now have a GUI for my #rust #GameOfLife
Will optimize the code a bit and try to test _some_ of the UI code with unit tests.

Then I might record a video, since I did not yet find one on youtube where someone implements it in Rust using #TDD (if you know such a video, please forward it to me).

Another implementation of game-of-life, this time in #Java and I tried to use some #functional constraints:

https://codeberg.org/dtanzer/game-of-life/src/branch/main/java-func-constraint

Didn't clean up the test file, that was not what I wanted to practice this time. Also, forgot to commit after each micro step during the #TDD cycle.

And it's probably my last game-of-life for some time, since this year's global-day-of-code-retreat is over. #gdcr

Made a first attempt of #tdd in #rust - Feel free to roast my code, happy to hear feedback! It's just the "prime factors" - kata, though: https://codeberg.org/dtanzer/rust-playground/src/branch/main/prime_factors

Also, should I use an assertion library? Found some, and "assert_eq!" seems not very powerful...

Fühlt sich Testing für euch auch oft wie eine Bremse an? 🐌 Die CI-Pipeline ist ewig rot, man schreibt Tests für Tests und am Ende liefert man trotzdem langsamer.

Das ist kein Sicherheitsnetz, das ist "Quality Theatre". Passiert, wenn Tests nur ein Ritual sind.

Automatisierte Tests sind nicht der Bremsklotz, sie sind euer Gaspedal. Wenn sie euch hindern, nutzt sie nicht.

Agilität braucht ein Sicherheitsnetz. Wie seht ihr das?

I've been teaching Test-Driven Development (TDD) for 6 months now, to 10 teams.

The feedback I have from these teams, 3 months after the sessions, is that of course they don't always use TDD, they use it sometimes. But most say that they now look at writing software differently.

I think they have integrated this way of "design is also in the smaller things", checking that it works all the time, and more communication inside and outside the team.

I'm so happy about these feedbacks!

iOS Test-Driven Development Describe Your Test in Plain English Quality Coding with Jon Reid Image of post-it note with test

Last commit message: "Build the updates for the email, using #TDD. This would have been too hairy otherwise."

Makes me pretty happy. For one, that I found when I want TDD and two that I really get very satisfying results. Code is readable, as simple as I could do it (now) and it was fun and 🥁 🥁 🥁 QUICK!

#testdriven #ftw when it's right, which is the hard part.

🤖 How can we combine #AI with #TestDrivenDevelopment without losing the human touch? @claresudbery shares insights from her workshop "How Can You Combine AI With Test Driven Development?" and her session "Let’s Stop Making Each Other Feel Stupid" on fostering learning, psychological safety, and human-centered practices in software development.💡

I don’t know if I’ll get the job, but I really enjoyed my interview today :) It was great to talk to people who advertise for #TDD skills and actually practice TDD themselves! #XP #Agile

#TDD is about practice, "instead of reading the menu you eat the food".
It's not about 'book learning', it is experiential. You can't study your way to expertise, you have to practice.
The practice changes you, changes your mind, changes your way of working, changes the way you think. It is transformative.
You don't need a mentor or coach for this, I didn't have one, but it does make it a lot quicker and easier to achieve competance.

Just published: Doing the simplest thing that could possibly work often involves incremental thinking: the engineering practice of splitting a large problems into smaller problems so that their resolution grows into the solution that you are looking for. Let's see a definition and a few examples. #Architecture #Engineering #SoftwareCraft #TDD #Video

Can AI coding agents do Test-Driven Development (TDD) properly? They sure can!

In this week's video I take a look at two approaches: prompt engineering & using the tdd-guard library

We'll run an experiment and compare results:
Does it improve code/test quality?
What are other trade-offs?
How does tooling like tdd-guard work behind the covers?

Here's how I started test-driving a SwiftUI counter app… https://qualitycoding.org/tdd-where-do-you-even-begin/ #TDD

A long-term client contract is ending in September, so I'll have some time in the last three months of the year. I want to spend a lot of it slowing down, learning, experimenting, ... and I'll write about it here.

I also have some capacity for training and technical coaching (Test-Driven Development, Agile Engineering, Domain Driven Design). Contact me to discuss more details if you are interested: DM here or business@davidtanzer.net
