This video is still relevant: “AssertJ — Use It Now!” 🚀 If you write Java tests, this one’s for you. Learn how AssertJ can make your assertions cleaner, clearer, and more powerful. Watch now: youtu.be/qn4AMKTPpg8 #Java #Testing #AssertJ #CleanCode #DevTips

🍃 Who replaced a third-party dependency with a Spring HTTP Service Client and is happy about it? 🙋‍♂️ In Spring Batch Notion, access to the Notion API was done via Notion SDK JVM, a Kotlin library that abstracts the REST communication. While it’s charming for a quick start, it has a few drawbacks: 🧵

As an early Christmas present (if you're celebrating), also to ourselves, we have overhauled our User Guide, Release Notes, and Javadoc. Check it out on docs.junit.org! Thanks to the @sovereign.tech agency for making it possible and to the @antora.org project for the excellent tool!

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 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? 1/3 ⏩

Hack.Commit.Push Switzerland 2025 was a success! Plenty of contributions made, with close to 20% of attendees making their first contribution ever 🤩

📢 Here is Spring Batch Notion 0.1.0, the first release since my project became an official Spring Batch extension! 🍃 Built on top of the Spring Boot 4 generation and Spring Batch 6! 🚀 github.com/spring-proje...

🤔 Who said that AssertJ 3 is in maintenance mode? 📢 We're planning an exceptional 3.28 release – let us know what you'd like to see in there! 👇 github.com/orgs/assertj...

#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 docs.junit.org/6.1.0-M1/rel...

TIL: #CGLIB has built-in support for saving generated classes to disk, such as those generated for #Spring #AOP proxies. 😱 Just set the `cglib.debugLocation` JVM system property -- for example: -Dcglib.debugLocation=build/cglib Can be quite useful for debugging! 🤓

Hack.Commit.Push Switzerland is just one week away! 🇨🇭 This is a great opportunity to get involved in Open Source projects like @assertj.github.io, with direct guidance from the maintainers!

Hi everyone! An ongoing reorganization at my current employer has prompted me to seek for a new role and would appreciate your support. I'm open to remote (anywhere) and hybrid roles in Switzerland. I have 25+ years experience as a software developer, 8 as devrel www.linkedin.com/posts/aalmir...

#JUnit has a new logo!!! 🚀 To everyone who submitted proposals and participated in the design discussions... Thank You! 👏🏼 github.com/junit-team/j...

#JUnit 6.0.1 is released! #️⃣ Introduce commentCharacter for Csv{File}Source 🔇 Allow disabling JUnit Vintage engine discovery issues 🐞 Bug fixes and enhancements since 6.0.0 docs.junit.org/6.0.1/releas...

#JUnit 5.14.1 is released! 🐞 Bug fixes and enhancements since 5.14.0 docs.junit.org/5.14.1/relea...

"Nobody stops in to check on you. They check on the project. There’s also nobody standing up and saying, ‘hey, thank you for the good work you’re doing to remediate this issue.’" The harsh truth: maintainers give their spare time, yet positive feedback is rare. Appreciate who is behind the code. 💛

As a fellow maintainer of an open source project, this is an intense and somewhat scary read. Thanks to @grobmeier.de for being so open to talk about what he experienced and @github.com for initiating their Secure Open Source Fund! github.blog/open-source/...

The internet was on fire. 🔥 One small library affecting billions of systems. Log4Shell was the biggest security vulnerability of all time. Now, Log4J maintainer, Christian Grobmeier tells us what it felt like inside the flames 👉 github.blog/open-source/...

Our next meetup will take place on November 4th at ING Leeuwarden to help you improve your testing with @timtebeek.github.io covering AssertJ and @simoneromani.bsky.social mutating tests for more confidence. Sign up at www.meetup.com/jug-noord/ev... !

It's great to see the community actively watching over the early development of AssertJ 4!
