Mobile applications have become an integral part of the daily lives of millions of users, thus making necessary to ensure their security and reliability. Moreover the increasing number of mobile applications with rich Graphical User Interfaces (GUI) creates a growing need for automated techniques of GUI Testing for mobile applications. In this paper, the GUI Ripping Technique is combined with the Input Perturbation Testing to improve the quality of Android Application Testing. The proposed technique, based on a systematic and automatic exploration of the behavior of Android applications, creates a model of the explored GUI and then uses it to generate the perturbed text inputs. The technique was evaluated on many Android apps and its results were compared with random input tests.

This paper presents a toolset for GUI testing of Android applications. The toolset is centered on a GUI ripper that systematically explores the GUI structure of an application under test with the aim of firing sequences of user events and exposing failures of the application. The toolset supports the execution of a testing procedure that automatically performs crash testing of subject applications and provides test results made of several artifacts. The paper illustrates some examples of using the toolset for testing real Android applications.
