Instead of spending Black Friday buying stuff I don’t really need, I’m sponsoring open source #Java projects that I rely on. Next up is SDKMAN! (sdkman.io). While I don’t use it as often as JUnit or AssertJ, it helps me manage my huge variety of JDKs installed.

SDKMAN! is a tool for managing parallel versions of multiple Software Development Kits on most Unix based systems.

Instead of buying more stuff that I don’t really need, I’m sponsoring open source #Java projects that I rely on, starting with #JUnit and #AssertJ (via core maintainers Joel and Stefano).
If I was a big company using Java, I’d be embarrassed at not sponsoring these projects.

And talk to your company first - they profit materially from JUnit, so they should contribute.

JUnit is undoubtedly one of the most important projects in the #Java ecosystem. And it's 100% free and open!
Let me be frank: If we can't get THIS project to the point where a single maintainer can focus on it, then what does that say about our commitment to Free & Open Source Software?

Spring Boot 4 looks amazing 🤩🍃 I have implemented OpenRewrite recipes to automate most of the migration process and handle the major breaking changes. You can run them with the Arconia CLI or using the OpenRewrite Gradle/Mavens plugin. Let me know what you think! I'm planning further improvements.

"Bruh they didn't even teach us junit college didn't prepare me at all for the real world"
Meanwhile you won't even write a *single language* forever on most *teams* let alone use the same framework forever.

Building Hot Reload for Compose is challenging. One of the bigger challenges is testing. I did not use JUnit but built a custom test framework for building Hot Reload Tests. I especially like that test methods can just be top-level functions ☺️
