Worked on the SmartThingsCommunity/SmartThingsEdgeDrivers repository to enhance the reliability of Zigbee Window Treatment Driver tests following v16 API changes. Addressed a persistent issue with test leakage by resetting the sequence number at the start of each test, ensuring proper test isolation and a clean state for every run. This targeted fix improved the stability of the continuous integration suite, reducing flaky failures and enabling more dependable validation of driver updates. Utilized Lua for test automation and applied strong unit testing practices, demonstrating careful attention to test hygiene and maintainability within the context of Zigbee protocol-driven device integration.
