The TestCentricity™ Web core generic framework for desktop and mobile web site testing implements a Page Object Model DSL for use with Cucumber, Capybara, and Selenium-Webdriver. The TestCentricity™ Web gem supports running automated tests against locally hosted desktop browsers (Firefox, Chrome, Safari, or IE), locally hosted emulated mobile browsers (iOS, Android, Windows Phone, Blackberry, Kindle Fire) running within a locally hosted instance of Chrome, a "headless" browser (using Poltergeist and PhantomJS), mobile Safari browsers on iOS device simulators or physical iOS devices (using Appium and XCode on OS X), mobile Chrome or Android browsers on Android Studio virtual device emulators (using Appium and Android Studio on OS X), or cloud hosted desktop or mobile web browsers (using the BrowserStack, Sauce Labs, CrossBrowserTesting, or TestingBot services).
