🎄 Advent of Donations - Day 21 🎄

On day 21 we have the first project from the Java ecosystem. And it's with no doubt the most important project for the JVM: @junit I use it for testing in every JVM project that I work on.

Read more about Advent of Donations and JUnit in my latest blog update: https://britter.dev/blog/2025/12/01/advent-of-donations/#day-21---junit

#AdventOfDonations #java #testing #junit

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.

#JUnit 6.1.0-M1 is ready for testing!

✨ New org.junit.start module for usage in compact source files
⚙ Execution mode configuration support for dynamic tests and containers
🏊 New parallel test executor implementation without ForkJoinPool

✨ New blog post: "STF Milestone 3: Release verification and automation"

A major goal of the @sovtechfund is to help projects become more sustainable and decrease their truck factor. For #JUnit, one activity in desperate need of improvement in this area was performing a release. Prior to this milestone, all JUnit releases of the past years had been performed from my local computer. It was high time to change that!
