4. Data-Driven Testing: Employ data-driven testing techniques by parameterizing your test data. This allows you to test various scenarios and inputs without duplicating test scripts, enhancing the efficiency and coverage of your tests on LG webOS TV.

How to Configure LG webOS TV for Appium automation?

Appium achieves LG webOS TV automation with LG webOS SDK and Chromium. LG webOS uses Web technology to build the TV application. It provides Chrome Web Inspector as the development tool. It means once you configure the developer environment, Appium can get the application information via the Chromium toolset.

Your machine should have LG webOS SDK. LG_WEBOS_TV_SDK_HOME environment argument should refer to the path to the installed SDK. Once you make the TV be developer mode, webOS commands such as ares-setup-device can set the TV device up for development. Once the setup is completed, the ares-device-info --device <name> command should work. 

It is necessary to achieve the LG webOS TV automation with Appium.
