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

I’m starting to look for a new job. Has anyone found a way to search for companies that do XP (Test Driven Development, Pairing/Ensembles, Trunk Based Development etc)?
Thanks!

In software development, we have many ways to speed up the time until we get good feedback (in this video, I talk about test-driven development or #TDD).

So, if we are in an environment where we get feedback slowly, we are choosing slow feedback - deliberately or by neglect.

Why are so many choosing slow feedback? https://videos.devteams.at/w/x5Hkwz6ey1GeNF5sZRKAcP

@jlink that's because "developer productivity" is hard to define and even harder to measure. All in all my key metric is shortening the feedback cycle(s). #TDD does a great deal in that. But you also have to do (real) continuous delivery. Even #AI can help with that (cycle time) when it comes to rapid prototyping and quickly explore an idea or technology.

If you really really want to increase your developers productivity, teach them proper #TDD and give them time to refactor.

so good I wrote #playwright tests yesterday, I knew the complexity was beyond me comprehending the validity of the code.
That's when I start applying tests and #TDD lately.

Why do I start testing so late?
Well I passed the line of the code being for throw away, since I am coming back and actively being interested in it keeping to work.

curious to see the tests? https://codeberg.org/wolframkriesing/spaish/src/branch/main/tests/details.spec.js

#OpenToWork Hi y'all.
I'm now properly looking for a new job, available from early September for a senior software role. Ideally, in #Kotlin or Java-to-Kotlin conversion. I think I can tick just about all the important boxes for backend development and some more. (especially XP, #DevOps, #TDD, trunk-based development, pairing, fast feedback cycles). Ideally, #remote or flexible #HybridWorking in #London (the one in the #UK).

Would it be possible to transfer the test-driven development paradigm over to writing fiction? Test-driven novel writing? I think so!

What is Test Driven Development (TDD) and how can it speed up your software development? In this Making Tech Better podcast episode, I spoke to @GeePawHill about why he loves TDD so much and how he has spread that love to software teams all over the world.

I find that the issue Kent Beck talks about here:

https://tidyfirst.substack.com/p/why-tdd-doesnt-lead-to-dumb-code

... is very fundamental to TDD and centers around a couple of commonly missed aspects of it (even though they are spelled out in Test Driven Development by Example)

1- When passing the test, there is a Fake It approach you can take if you don't see the Obvious Implementation right away before you move on to Triangulation and add more tests.

2- When you are using Fake It, the Refactoring step is not primarily about making the code "nicer", but generalizing by removing the duplication between the test and the production code. This is only refactoring in the sense that you are staying green. That's why the step is not optional and getting to green using the simplest, naive implementation is a core part of the process.

I think not using Fake It is one of the two main reasons people fail with TDD (the other is not making writing more testable code a design goal.)

_Event-Sourcing Live Coding_

I've been live coding an example #EventSourcing app in #Java (via #TDD) w/o an ES library.

This week I'll continue to code the "Time-Traveling Event Viewer" to view the state at any point in time.

@GeePawHill

One danger of a too transparent box used for TDD is that tests get too coupled to a specific implementation and thus hinder refactoring and evolution. ie, taking the soft out of software.

Sure you are aware of that, but novices easily fall into that trap, when they not have learned enough about refactoring towards simpler code.
