Announcing Appium on Sauce: Native & Hybrid iOS App Testing in the CloudToday we are extremely excited to announce the initial release of Appium on Sauce, a new way to automatically test your native and mobile web hybrid iOS apps in the cloud.Appium on Sauce has its roots in Appium, an open source project written in Node.js that draws from Dan Cuellar's work on iOS Auto. It supports iOS testing with Android support in the works. Using the WebDriver JSON Wire Protocol to drive Apple’s UIAutomation, Appium takes Selenium commands from your app and translates those into a readable format for UIAutomation. With this seamless transition happening under the hood, Appium requires no recompiling or modifications to your app, allowing you to write tests in your favorite programming language and testing frameworks using the Selenium API and language-specific libraries. This service provides out-of-the-box compatibility with Selenium, cross-platform support across iOS and Android, and a flexible approach to automation. It also allows for parallel test runs across dozens of machines, significantly reducing test completion time. Appium on Sauce can be integrated into existing CI setups as a build server, making it an attractive option for mobile app developers and testers. The service is currently available by invitation-only but plans to open up to everyone in the coming weeks.
