The TestCentricity™ core framework for native mobile iOS and Android apps and desktop/mobile web testing implements a Page Object Model DSL for use with Cucumber, Appium, Capybara, and Selenium-Webdriver v4.x. The gem also facilitates the configuration of the appropriate Appium capabilities required to establish a connection with locally or cloud (using BrowserStack, Sauce Labs, or TestingBot services) hosted iOS or Android devices or simulators. For more information on desktop/mobile web testing with this gem, refer to docs for the TestCentricity™ Web gem (https://www.rubydoc.info/gems/testcentricity_web).
