New blog post: Reflecting on STF support and looking ahead

Thanks to the @sovtechfund, I was able to work full-time on #JUnit for about 16 months in 2024 and 2025. It’s time to reflect and assess whether that effort really did improve the long-term sustainability of the project. Moreover, I’ll share a look ahead at what’s next for me and for JUnit.

How #Uber Executed A #JUnit Migration at Massive Scale https://www.uber.com/us/en/blog/junit-migration/

Flaky GitHub Pull Request builds are an annoying reality in many projects. Just when you think a change is complete and good to merge, you are greeted with an ❌. To unblock your PR, you need to rerun lengthy test pipeline just because of one rogue test.

If you have a Java project on GitHub, TestLens can help you:

✨ 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!
