I'm still looking for a new #freelance #remote #project in #software #RnD.
I offer #agile (#team) #coaching or whatever you name it and a lot other stuff. I wouldn't reject any role which I already had, eg. Architect, TeamLead, Product Owner etc...
My skills reach from #Java #Kotlin #Swift #mobile or #backend #TDD #CICD pipelines, project setups or firefighting to #liberatingStructures and merging and splitting teams/departments and organising company wide initiatives.

When figuring out what was needed for "find all events after a given checkpoint", that was on the Discovery/Design side of #TDD. Once I had that defined (an interface and 2 implementations), then I could move completely into implementation, using the tests to take safe steps.

On my #Java live coding stream today, when implementing the JDBC implementation of my Event Store, I talked about doing #TDD for Discovery and Design (learning about what the desired behavior should be), vs. implementing a known behavioral specification.

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

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.

Was fun to chat here dev2next with Baruch Sadogursky from TuxCare on #VerboseMode about TDD, AI, and JitterTed's TDD Game (https://tdd.cards)

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

When naming tests, avoid using technical names of functions/classes. When we encorporate the name of a function into the descriptive name of a test method, and the respective function is later renamed, then the description of the test becomes completely useless. A better approach is to describe the behaviour of the production code under test. That way we can refactor more confidently without rendering the names of our tests as obsolete.

#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
https://mozaicworks.com/blog/examples-of-incremental-thinking?fsp_sid=235

The best thing about TDD is not necessarily the tests thats we write, but rather the instant feedback that we get from the decisions that we make during coding sessions. Especially when those decisions are related to the design of the system that we're working on.

Assertion libraries can be considered as mini-DSL’s that make automated tests more readable. When a team of devs make their choice, they usually judge on API preference. While it’s very important to have readable tests, the API should never be the deciding factor. What truly separates a good assertion library is the quality of its failure messages. The more actionable these messages, the faster you’ll diagnose the cause of failing tests.

Test doubles expose design flaws in the code. Developers usually tend to respond to the pain that this induces by blaming test doubles instead of interpreting these signals as an issue with the design. If solitary tests are amplifiers for design flaws, then test doubles will amplify these design flaws tenfold.

Reflecting on 25 years as a software developer—a milestone I reached last July—I’m struck by how much the industry has evolved. I’ve seen hypes rise and fall, technologies come and go. However, there’s one thing has remained a constant: the value of Extreme Programming. I’ve been fortunate enough to learn and study the core values and practices of XP early in my career. I can only say that it has paid dividends ever since, for which I'm more than grateful.

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?
