 | MS-20 |   Done   | Update event registration in MobScoresPlugin to use getServer().getPluginManager().registerEvents(...).
 | MS-21 |   Done   | Replace all usage of org.bukkit.util.config.Configuration with the modern Bukkit configuration API (getConfig(), saveConfig(), reloadConfig(), etc.).
 | MS-22 |   Done   | Remove or refactor any code using deprecated or removed Bukkit/Spigot/Paper APIs that are not available in the modern Paper API.
+| MS-23 |  Ready  | Add JUnit 5 test infrastructure and keep the default Gradle `test` task server-free. Use an in-memory Paper test harness such as MockBukkit for plugin lifecycle and Bukkit/Paper behavior; use Mockito or test doubles for ScoreKeeper and narrow API boundaries where a harness is unnecessary. |
+| MS-24 |  Ready  | Add fast unit tests for MobScores behavior: default and configured score-table loading, serialization and malformed or unknown entity entries; direct-player and projectile damage attribution; ignoring untracked entities and non-player damage; death awards, offline credited players, zero-value scores, and join-time score messages. |
+| MS-25 |  Ready  | Add a separate Gradle `integrationTest` source set/task for behavior requiring a real Paper server with the built MobScores and ScoreKeeper jars installed. Verify plugin loading and ScoreKeeper compatibility, mob-death score awards and player-facing messages, and score-table persistence across a server restart. Run it only when explicitly requested; keep it out of the normal `test` and `build` tasks. |
