Java's Hidden Gems: Tools and Libraries
summary
A GitHub repo of about 70 tools and examples anchors concrete demos: ArchUnit architecture rules that run as unit tests, JaCoCo runtime coverage that finds dead code but only writes results when the app stops, and PIT mutation testing that generates mutants and exposes weak tests at the cost of slower runs. Also shown: Testcontainers for real DB integration, JavaPoet code generation, libphonenumber validation, Timefold scheduling that fails when sessions exceed rooms, and Maven Daemon for faster builds.
