Any software developer knows the importance of testing their project both during and after development in order to find and debug errors. While the majority of developers focus on testing internal functionality of the app, testing the user interface is also very important. One way to test your app is to manually use it, but that can get tedious with all of the different possible inputs and outputs. This is where testing frameworks come in handy, by automating the process. Google just made UI testing easier by providing a UI testing framework.
Shared with us in a tweet by Android Engineer Romain Guy, this framework is now available in the latest Android 4.2 SDK and requires Android SDK Tools Revision 21 or higher with Android SDK Platform API 16 or higher. It has two components: the uiautomatorviewer GUI tool for scanning and analyzing the GUI components of your app, and the uiautomator Java library that offers the required APIs for automating customized UI tests and an execution engine for running them. Complete details and instructions can be found at the Android Developers Website._________
