In an older post from 2013 I briefly described the Android test automation tool called Espresso. Espresso is the test automation framework provided by Google to implement fast and reliable tests for Android apps. Since last year Espresso is available in the version 2.0 and has fixed lots of issues and is now supporting most of the Android UI elements.
