Many developers who are currently testing mobile apps are using the popular Appium framework. With Appium’s rise in popularity, it’s easy to overlook other alternative frameworks and strategies for mobile app testing. This webinar will explore the Espresso testing framework, another widely used framework for testing mobile apps for the Android OS. Espresso provides APIs for writing UI tests to simulate user interactions within a single target app. Join Asaf Saar, Sauce Labs Mobile Product Management Director, and Clint Sprauve, Mobile Product Marketing Director and learn: -About the Espresso testing framework and who uses it -The differences between Espresso and Appium -The key advantages of the Espresso testing framework Also, see a live demo of Espresso used on real Android devices on the Sauce Labs Real Device Cloud.
