You can change the language of a device during a AI Scriptless test to validate localized behavior across system UI, apps, and browser flows. This feature supports both iOS and Android and helps ensure end-to-end test coverage in different languages. It eliminates the need to manually navigate device settings or maintain separate devices for each language configuration.
