The **@iobroker/testing** package supplies a set of helpers for writing automated tests for ioBroker adapters and related modules. It offers (now‑deprecated) mock‑based unit‑test tools as well as full‑stack integration test utilities that spin up a real JS‑Controller instance, letting developers validate package files, adapter startup, message handling and state/object behavior with minimal boiler‑plate. It is aimed at ioBroker adapter developers who need reliable, reusable test scaffolding.
