Sauce Labs provides the world’s largest cloud-based platform for the continuous testing of web and mobile applications. Optimized for Continuous Integration (CI) and Continuous Delivery (CD), Sauce eliminates the time and expense of maintaining an in-house testing infrastructure, freeing development teams of any size to innovate and release better software, faster. Users can run tests written in any language or framework using Selenium or Appium, both widely adopted open source standards for automating browser and mobile application functionality. Videos, screenshots, and HTML logs help pinpoint issues faster, and Sauce Connect allows you to securely test apps behind your firewall.
