Robotium makes it easy to write powerful and robust automatic black-box UI tests for Android applications' and is an app in the Development category. There are three alternatives to Robotium for Windows, Android, iPad, iPhone and Mac. The best alternative is Appium, which is both free and Open Source. Other great apps like Robotium are TestComplete (Paid) and Repeato (Freemium).
