I am looking for a code name for the next version of ui5-test-runner. My hope is to go with "FTL" but "FTK" (Faster Than Karma) will also do it ;-)

Wouhou ! I created a multithreaded logger in Node.js... The goal ? * free up bandwidth for CPU intensive tasks, * have a synchronous (hence thread blocking) compressed (hence CPU intensive) trace storage, * implement a nice console output which does not block other threads. was a fun ride !

Playing with Node.js threads (i.e. Worker)... It's a brand new world...

"You're absolutely right! " ...thank you LLM...

It’s a big responsibility when you decide to completely rewrite a component. Yet, I take this opportunity to improve all the little details that were bugging me over the last 5 years. It will take time but it should be rewarding.

More than 80 different options for the ui5-test-runner command line. Quite some work to clean the mess and make it maintainable...

I gave a presentation tonight about MetaProgramming at JS Montreal. Got good feedback. arnaudbuchholz.github.io/decks/MetaPr...

I like refactoring: this is an opportunity to rewrite with the knowledge of all the faced challenges. Yet, this feels like a huge mountain to climb.

Sometimes I feel like when I want to ask a question to the LLM, I spend so much effort to formulate it the right way that I almost get the answer by myself...

Big release for [email protected] github.com/ArnaudBuchho...

Hmm... I'd remove #Ubuntu from that chart and replace it with #LinuxMint

My cat contribution

Tried to create a simple command line app with GEMINI to validate an idea... A bit disappointed (some mistakes) but got it to work. It certainly saved me a bit of time...

Using compression (& decompression stream) I was able to reduce the HUGE html report (168 MB) down to 9 MB... and it loads fine (& fast) in the browser !

So... you can actually decompress content inside a web page. Today I learned about DecompressionStream : developer.mozilla.org/en-US/docs/W...

Got it, trying to open a 168 MB HTML report is not a good idea...

OK QUnit is old... but it is good ! Believe it or not but I am currently mapping jest APIs to QUnit... and it works !

From 6 min to 4 min with a simple trick... Sometimes optimization really feels great !

2 hours to enable my apple device on my Windows 11... I had to extract drivers from an old version of iTunes to make it work... Just why ?!?

Working on automating OpenUI5 existing tests with ui5-test-runner (since karma is no more maintained). Some metrics on sap.ui.core tests : - 600+ unit tests - 17 minutes to execute (10 parallel executions) - 29+ tests failing (need to check) - A 172 MB HTML report (!) Room for improvement !

Something big is coming soon to ui5-test-runner... I never thought I would be able to achieve a bridge between jest and QUnit. The reality is that both JavaScript and QUnit are powerful tools.

Learning about meta programming: a programming technique where programs manipulate or generate other programs as data. That’s what I am doing !

Just released version 1.2.0 of punyexpr, a minimalist (5085 bytes) and safe expression compiler and evaluator. www.npmjs.com/package/puny...

I am currently working with Abstract Syntax Tree to manipulate JavaScript code... I feel like a surgeon trying to transplant an organ : tricky but fun !

I don't know why it happens now but I like the trend !

Just updated punyexpr, it now exposes types definition and can be used in a CommonJS or ESM project. arnaudbuchholz.github.io/punyexpr/sam...

🚀 Exciting news! Version 5.7.0 is here, introducing new options for test automation using selenium-webdriver and a docker running the selenium server. This update marks the initial phase in setting up test grids with ui5-test-runner. github.com/ArnaudBuchho...

Yesterday, I had the opportunity to present my personal project psbots at JS Montreal. I showcased the engine's capabilities through an online REPL and a PONG game, where the paddles were controlled by a compact PostScript program. arnaudbuchholz.github.io/decks/psbots.html

Cool LLM visualization bbycroft.net/llm

Fixed a bug that was preventing code coverage to work when doing library testing... The runner is more and more used ! github.com/ArnaudBuchho...

Est-ce qu’il y a une communauté JS en Français ?

Every day I'm learning... www.npmjs.com/package/happ...

Big ui5-test-runner release today : 5.5.0 ! Introducing the batch mode : it is now possible to test more that one project with a single command ! github.com/ArnaudBuchho... #ui5 #testing-ui5

Just released [email protected] : a lightweight web server configurable with regular expressions. I added the possibility to build responses directly through the custom handler result. github.com/ArnaudBuchho... (REserve is a core part of ui5-test-runner)

I wanted to share with you this little tool I built a while ago : arnaudbuchholz.github.io/punyexpr/sam... The idea is to have an expression parser that is safer than eval and extensible. I integrated it in ui5-test-runner to condition some executions !

I am delighted to announce that I have been recognized as an #SAPLabsCanadaAllStar in the #Grit category. It is a privilege to be among such esteemed colleagues who exemplify the spirit of SAP Labs Canada. #SAPLabsCanadaAllStars #SAPMapleMagic #SAPCanadaLifts

regex101.com Probably the best (only?) tool you need to work with regular expressions.

Is it me or the ESLint 9 flat configuration thingy is a big mess ?!? #JavaScript #TypeScript

How to implement the factorial function in postscript... and run it inside psbots. arnaudbuchholz.github.io/psbots/ #TypeScript #learningisfun

Just published a POC for my PONG with paddles controlled by a script... It demonstrates how two instances of the psbot engine run two different objets within 60 fps rendering range (even when running at x1000 speed). arnaudbuchholz.github.io/psbots/ #TypeScript

Using node profiler on my code made me realize that RegExp are convenient for parsing strings but might be slower than actual implementation of a parser... I need to do more testing.

Gaming alert ! Humankind (a 4x game) is free on Epic games for this week. store.epicgames.com/en-US/p/huma...

Been comparing the performances of my latest engine with different hosts : * node : ~2000 cycles/ms * bun : ~1700 cycles/ms * deno : ~1000 cycles/ms The tested code is 100% JavaScript with *no* dependencies... #JavaScript

Thinking about migrating my got, axios and other HTTP clients with fetch. This mock implementation will make it easy ! #JavaScript humanwhocodes.com/blog/2025/01...

Funny to observe the boom on my testing UI5 article that I wrote 4 years ago... now that ui5-test-runner is becoming more and more popular. medium.com/p/85187d5eb7f1

[email protected] is out. Some teams reported a regression in 5.4.x after I fixed the configuration file parsing issue. it appears that the tests (and particularly chrome) works better if an extra command line parameter is added to the chrome browser args.

It's funny to see how removing exceptions in a code base forces you to care about "details" : * call a method that may throw : mostly you won't do anything, easy to get 100% coverage. * replace exceptions with a function result and, boom! you realize that there are situations you didn't expect !

Discovering a new TS feature : www.totaltypescript.com/erasable-syn... Sounds interesting... will have to investigate what it means for my projects. #typescript
