The Road to JUnit 6
summary
2025 funding from the Sovereign Tech Fund pays one developer full time for ~1.5 years and produces three releases: 5.12 (Feb) adds Open Test Reporting XML with output capture, file attachments and an HTML reporter (already adopted by PHPUnit); 5.13 (May) adds parameterized test classes to ease migration from JUnit 4; 6.0 (fall) raises baselines to Java 17 and Kotlin 2.x, adds Kotlin suspend support, discovery-issue failures, safe test cancellation, and plans to replace fork‑join for parallel execution in 6.1. Support subscriptions via Open Elements fund maintenance.
