Appy Friday! Sauce Labs' Support Team wants to help customers easily ramp up their mobile automated testing by providing an easy guide to integrating Appium with Sauce Labs. Appium is an open-source tool used to automate tests for mobile native, web, and hybrid applications, offering cross-platform capabilities and flexibility in writing and running tests. It was created by extending the Selenium Webdriver JSON Wire Protocol with extra API methods for mobile automation. The integration with Sauce Labs allows users to run tests on multiple platforms, including iOS and Android, using a single tool. Sauce Labs uses Appium as the server for their latest iOS simulators and Android emulators, making it easy to start testing with this powerful combination.
