Gadgeon Systems developed an ultra low cost IoT home gateway with associated cloud and mobile apps to secure homes from fire, flood and freeze. A team of 5 used Python, Selenium, Appium and Jmeter to test the end-to-end use cases involving the hub, mobile app and cloud server. Gadgeon's experts designed a test strategy and custom framework to ensure coverage of features across WiFi, Zwave and ClearSky protocols and verify system performance and scalability with large numbers of devices.
