Mobile applications are being used every day by more than half of the world's population to perform a great variety of tasks. With the increasingly widespread usage of these applications, the need arises for efficient techniques to test them. Many frameworks allow automating the process of application testing, however existing frameworks mainly rely on the application developer for providing testing scripts for each developed application, thus preventing reuse of these tests for similar applications. In this paper, we present a novel approach for the automation of testing Android applications by leveraging machine learning techniques and reusing popular test scenarios. We discuss and demonstrate the potential benefits of our approach in an empirical study where we show that our developed testing tool, based on the proposed approach, outperforms standard methods in realistic settings.
Producing a tool that will allow testing any arbitrary mobile application automatically is an extremely challenging problem, perhaps nearly as difficult as the underlying general software testing automation task. Throughout the years, there has been an extensive study in the field of testing automation of . However, a recent study by @cite_8 has discovered that many of the mobile application bugs are unique and tend to be different from the ones presented in traditional desktop applications, mainly due to the inherent difference in architecture and development methodologies. Thus, traditional approaches for desktop applications testing cannot be naturally translated into mobile applications.

Users increasingly rely on mobile applications for computational needs. Google Android is a popular mobile platform, hence the reliability of Android applications is becoming increasingly important. Many Android correctness issues, however, fall outside the scope of traditional verification techniques, as they are due to the novelty of the platform and its GUI-oriented application construction paradigm. In this paper we present an approach for automating the testing process for Android applications, with a focus on GUI bugs. We first conduct a bug mining study to understand the nature and frequency of bugs affecting Android applications; our study finds that GUI bugs are quite numerous. Next, we present techniques for detecting GUI bugs by automatic generation of test cases, feeding the application random events, instrumenting the VM, producing log trace files and analyzing them post-run. We show how these techniques helped to re-discover existing bugs and find new bugs, and how they could be used to prevent certain bug categories. We believe our study and techniques have the potential to help developers increase the quality of Android applications.
