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 ⏩

Many thanks to you, @mcpringle.bsky.social, and Alexandra, for the amazing organization! 🙏 So many new contributors to @assertj.github.io in a single day! github.com/hack-commit-...

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

🤔 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...

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!

Sur le blog de #norsys, mon collègue Kelean vient de publier un billet qui présente @assertj.github.io et comment le mettre à profit pour améliorer ses tests unitaires. medium.com/norsys-octog... #JUnit #AssertJ #Java #Test #TestUnitaire

"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. 💛

Hard assertions = fast feedback ✅ But when one failure hides others, you lose valuable insight. 😥 Here’s how to use custom soft assertions with AssertJ to make your tests graceful, readable, and thorough: eliasnogueira.com/assert-with-... #java #testing #quality

Last morning talk at #KCDC2025: @jeanneboyarsky.bsky.social is teaching us about testing beyond JUnit. Here, she’s covering @assertj.github.io

📢 AssertJ 3.27.4 has been released! This fixes a 🐛 regression introduced in 3.26.0, brings a few minor 🚫 deprecations, and paves the way for ⚡ smoother NullAway integration. Happy assertions! github.com/assertj/asse...

Want cleaner, more expressive tests in Java? ✅ Avoid endless try-catch ✅ Group failures with elegance ✅ Use AssertJ the right way Soft assertions can raise your testing game without clutter. Learn how: eliasnogueira.com/assert-with-... #java #quality #test #qualityengineering

Should we establish a dedicated space for the AssertJ community on Gitter? Cast your vote! github.com/orgs/assertj...

FYI, if you need to compare 2 objects in a #java test, do not manually compare all fields by calling the getters. Instead, do it with 1 line of AssertJ: medium.com/@lucascalebe...

The Moderne world tour continues! ✈️ Next up, meet us at @springio.net ‬in beautiful Barcelona, May 22-23. 🤝 Don't miss @timtebeek.github.io's session, "Better Assertions with AssertJ" ☕ Details: 2025.springio.net/sessions/bet...

If you need a quick introduction to AssertJ-DB, my talk at Devoxx is available on youtube : youtu.be/XILu4r3rIEc #AssertJDB #AssertJ #tests

📆 One month left! Join us for a full day of open source on June 13th!

l'd be happy to help you get started with an AssertJ contribution, and there'll be other cool projects too-don't miss the opportunity!

Mille mercis à toutes et tous pour vos feedbacks 🤩. Avec @paulinejamin.bsky.social , on a eu bcp de plaisir à jouer pour la 1ere fois en conf « the DDD Horror Picture Show » à @devoxx.fr #DevoxxFR Merci aux orgas et au CFP de nous avoir fait confiance. 🙏

And here we are! #VDZ25

Have you looked into AssertJ? It's my favorite assertion library for Java, typesafe overloads of assertThat(...) make for great auto-completion.

📢 AssertJ 4.0.0-M1 has been released! 🚀 Required Java version increased to 17 🧩 Module-only build and modular Javadoc 🚫 Existing deprecations marked for removal Happy assertions! github.com/assertj/asse...

Want to know more about AssertJ-DB? Here's your chance to meet the project lead at @devoxxfr.bsky.social !

⚙️ Elevate your Java testing with custom assertions using AssertJ! Clean up your test cases and improve readability. 👉🏻 Guide here: https://buff.ly/3VSI5OE #java #testing #assertj

Used @openrewrite.github.io to replace all assertions in EqualsVerifier's unit tests with @assertj.github.io assertions. It only took a few minutes thanks to OpenRewrite, and I really like the expressiveness I gain with AssertJ! #java

AssertJ 3.27.0 has been released! • One 🚫 deprecation • Many ✨ new features, ⚡️ improvements, and 🐛 bug fixes Many thanks to all contributors and happy assertions! github.com/assertj/asse...

Thank you @egs-hub for sponsoring me on @github ! Much appreciated.

When starting #bjForth, I spent some time writing builders for my tests so they read naturally. That, paired with the custom assertions I wrote with #AssertJ, has really made my test code read very fluently. An upfront investment I don't regret at all 😎 #Programming #Java #JVM #Forth #TDD

AssertJ-DB 3.0.0 Released #assertj #database #java github.com/assertj/asse...

`extracting(Function...)` is now smarter thanks to four amazing first contributors! github.com/assertj/asse...
