Mar 1, 2025March 2025 (thingsboard/thingsboard-edge) - Focused on strengthening reliability testing for the ComponentActor and improving testability through a visibility adjustment. Implemented unit tests for scheduleStatsPersistTick and destroy methods, introduced ComponentActorTest, and adjusted the scheduleStatsPersistTick visibility to package-private to support robust test coverage and safer future changes. These efforts reduce regression risk, improve maintainability, and accelerate QA in upcoming releases.
