What's an important announcement without a blog post that dives into the full details? Nothing, I tell you! So here's all you need to know about the move from Amper to Kotlin Toolchain: blog.jetbrains.com/a... And of course, you also get lots of new features in this release!

Removing so many experimental compiler flags while updating my projects to #Kotlin 2.4 😍 If you missed out on "allow-contracts-on-more-functions". Kotlin Contracts now support generic 🔥 You can create a predicate that checks generic values, and they get smart-casted after a predicate check 👇

Nmcp 1.6.0 removes a bunch of checksums making it easier to respect your Maven Central upload quota github.com/GradleUp/nmc...

Had a great time with Kotlin User Group Berlin at N26 HQ, talking about TestBalloon! A big shoutout to the organizers Paolo and Matthias for a perfect event with super-friendly people and generous catering in a gorgeous venue. I very much enjoyed the interaction with the Berlin crowd. I'll be back!

On Thursday, June 18, I'll be joining the Kotlin User Group Berlin at N26 HQ with a talk about TestBalloon – Kotlin testing is easier (and more fun) than you think. I'm very grateful for the invitation and would love to see as many of you as possible. Let's have fun! www.meetup.com/de-de/kotlin...

Back from #KotlinConf26 in Munich, Kodee is seeing endless possibilities. Me as well! Grateful for all the inspiring exchanges with incredibly smart and lovely people, and so happy that the talk on 🎈 TestBalloon was so well received. ❤️

Was für eine geniale Folge. 🧠 Gehirngerecht, emotional, faktentreu, und mit Spaß: Das bewegt, und zwar in die richtige Richtung. Danke @positivemaren.bsky.social!

Thanks a lot @androidweekly.bsky.social for featuring TestBalloon's stable release announcement today. Let's bring powerful testing with ease to the entire Android & Kotlin Multiplatform ecosystem!

🎈 TestBalloon reaches flight level 1.0.0 🎉 The Kotlin test framework built from the ground up for today's ecosystem is now stable, with a powerful and concise DSL-based API, robustness at scale and first-class support for all platforms. infix-de.github.io/testBalloon/... More at KotlinConf!

Great achievement for Metro. Congrats to @zacsweers.dev and everyone involved! Now which project is next on the path to stabilization? 😉

Andrew reminds us that delivered value matters – not LLM-generated PRs waiting in review queues. If you're attending KotlinConf in Munich, come to my talk and see how new approaches in testing can contribute. In any case, consider reading this fine article. andrewmurphy.io/blog/if-you-...

Made TestBalloon 🎈 (local dev version) play nicely ❤️ with Amper (v0.11.0-dev-3793) out of the box:

Upcoming Kotlin releases (2.3.21-RC and 2.4.0-Beta2) fix KT-82395, paving the way for TestBalloon to support incremental compilation for JS and Wasm targets. Yay!

April Fools' Day, GitHub CodeQL version. Or maybe just TestBalloon being ahead of the curve again.

Finally status codes that make sense!

Couldn't sleep. Wrote a KEEP.

Apparently Kotlin/Wasm/WASI is now too fast for my 🧠 wetware's HTML decoding unit, but fortunately I can always hit ⏯️.

In a world of inverted truths, #502 implies that @kotlinweekly.bsky.social is actually an excellent gateway to carefully curated content every Sunday. Happy to see my article on TestBalloon flexibility featured in this episode.

Challenging the flexibility of TestBalloon, the DSL-based, Kotlin-first test framework. How much freedom does its API really support? How far can we go if we want to change its look and feel? Join me on my dogfooding journey! infix-de.github.io/testBalloon/...

Are you confused by Gradle terminology? What's a module, a configuration, a build, a project? Unless you're deep into Gradle, they probably aren't what you think. I wrote an article to organize all of that → ivan.canet.dev/blog/2026/03...

Android testing at scale is either fast or easy, never both, right? Integrating a modern DSL-based Kotlin test framework with class-based Roboelectric was considered impossible by genAI and others. Yet here it is: Roboelectric meets 🎈 TestBalloon infix-de.github.io/testBalloon/...

Guidance I have been waiting for. 🎉👏❤️

Arguing about unit tests vs. integration tests sucks. It's dogma and I feel like a heretic. This post discusses a different way to think about a test’s scope. I love it.

genAI: "This PR reverts the attempted Robolectric integration due to fundamental architectural incompatibility between TestBalloon and Robolectric." Human: "Hold my beer." github.com/infix-de/tes...

Grateful and happy to be appearing on stage at @kotlinconf.com in May! Looking forward to seeing you all in Munich.

TestBalloon 🎈 0.8.0 is out, the Kotlin-first test framework. Conciseness and flexibility meet JUnit*-like testing powers on all platforms: Scope-friendly, anti-boilerplate DSL, function calls create tests (parameterizable), nesting fixtures, all easily customized. ♥️ Yours? github.com/infix-de/tes...

Reminder that in 2026, just like in 2025, `*.main.kts` files are better replacement for most of your scripting needs! mbonnin.net/2024-11-21_s...

So I tried to find out where the action is for Paris API days. Then Apple Maps started to show Russian text on one of its buttons!?

Just 6 months after a small-circle demo at KotlinConf, TestBalloon has achieved its first 100 stars on GitHub today. ♥️ On a mission to make Kotlin testing incredibly easy, its trajectory is showing lots of upwind, even compared to the wildly popular (and excellent) Ktor. github.com/infix-de/tes...

TestBalloon, the next generation Kotlin test framework, has now reached flight level 0.7.1. Please do check out its unique combination of characteristics, making it 🌋 powerful, 🚀 blazingly fast, and ☺️ so easy to use. There's a brand-new documentation site, too! github.com/infix-de/tes...

YouTrack today:

We released Compose Hot Reload 1.0.0-rc01 🎆 What started as a happy accident was promised to be pushed towards stability as quickly as possible, allowing you to rely on a stable user experience. github.com/JetBrains/co...

Added some KDocs, this can be tested already, release coming closer. Implemented last missing feature and added localization bundles. github.com/karmakrafts/...

This is an amazing accomplishment by the Compose Multiplatform and Wasm teams at JetBrains, as well as everyone else contributing. I am so happy that they finally got this far!

Took this F18 race catamaran to a beach bar. Having the unusual combination of a non-alcoholic beer, coffee and chocolate cake. 😎

Entertaining, insightful, inspiring. A perfect start into the weekend. 🚀

😂 When TestBalloon completes 1.4 million tests in under 10 minutes and IntelliJ IDEA needs 6 minutes extra time to process the test results.

grug some very good points in there! grugbrain.dev

Sunday writing about why (and how) you should isolate your plugins work. mbonnin.net/2025-08-24_i...

TestBalloon 0.6.0 is out now, welcoming Android to next-generation Kotlin testing: ✅️ Android local tests and Android instrumented tests in addition to KMP. ✅️ Nested, concurrent and parallel tests on the Android platform. github.com/infix-de/tes... I'd love to hear your thoughts! Please share!

🤓 Fascinating read about OpenAI, Anthropic and the business of LLMs ethanding.substack.com/p/openai-bur...

What if TestBalloon's next release would lift Android instrumented tests to a new flight level? github.com/infix-de/tes...

Another round of valuable 🧑‍🍳 advice helping you write Gradle plugins with confidence:

A recent discussion has led me to realize that many folks do not fully grok the parts of Gradle that can be made parallel. By default almost all of Gradle runs in a serial way. So I wrote a post about it www.liutikas.net/2025/07/29/P... #gradle

Finally announcing a brand-new Kotlin Multiplatform test framework: TestBalloon is now ready for you to explore, built from the ground up to make writing all kinds of Kotlin tests simple and fun, everywhere! Please share, tell me what you think! github.com/infix-de/tes...

Version 0.34.0 of the gradle-maven-publish-plugin finally comes with configuration cache support. Dropping support for Sonatype OSSRH unblocked us from waiting for Gradle to resolve the underlying issue on their side. github.com/vanniktech/g...

A great breakdown by @mbonnin.net on why you should avoid the "kotlin-dsl" Gradle plugin. Just write your binary plugins using a normal "org.jetbrains.kotlin.jvm" plugin mbonnin.net/2025-07-10_t... #gradle
