## Summary After FLINK-39124 migrated modules to JUnit 5, `TestNameProvider` (a JUnit 4 `TestRule`) is never triggered. This causes `PseudoRandomValueSelector.randomize()` to always get `null` from `getCurrentTestName()`, making all boolean config randomizations (e.g. `ENABLE_UNALIGNED`, `UNALIGNED_DURING_RECOVERY_ENABLED`, `SNAPSHOT_COMPRESSION`) select the same fixed value across all tests. **Fix:** - Make `TestNameProvider` also implement JUnit 5 `BeforeEachCallback` / `AfterEachCallback` - Register it globally via `META-INF/services/org.junit.jupiter.api.extension.Extension` in all modules ## Test plan - [x] Verified that `PseudoRandomValueSelector` log output now shows varied `true`/`false` values instead of all `false` -- This is an automated message from the Apache Git Service.
