love that #JUnit actively posts on their :mastodon: page, more frameworks should do that

So, do you still think that #JUnit 5 is "the new" thing?

It quite isn't.

The crowdfunding campaign for JUnit Lambda was ten years ago this year.

When @sormuras and I realised that last week at #JCON that made me feel old.

JUnit still rocks, though. Great #Java framework.

#JUnit 5.13.0-RC1 is ready for testing!

🪄 ClassTemplate and ParameterizedClass support
⚠️ Discovery issue reporting for test engines
♻️ Resource management for launcher sessions and execution requests
🔍 Test discovery support in EngineTestKit
🐞 Bug fixes and minor improvements

Migrating a large set of #JUnit 4 to 5 (Jupiter) unit tests and it's a bit annoying, because most assertions have a "message" parameter which was at the first position before and must be at the last now, with Jupiter.

Streaming about testing library for Scheme, NLnet grant, its integration into Arei/Ares Guile IDE and some library architecture design thoughts in a couple hours. It's inspired by clojure.test and junit, but still quite schemy.

✨ 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!

[Перевод] Сравнение SpringRunner со SpringExtension и @SpringBootTest

Команда Spring АйО перевела статью о том, как и когда использовать SpringRunner , SpringExtension и @SpringBootTest , когда их целесообразно комбинировать и как правильное понимание этих компонентов может помочь сделать тесты проще, быстрее и более узконаправленными.
