Software testing of mobile applications: Challenges and future research directions

While mobile applications are becoming so extraordinarily adopted, it is still unclear if they deserve any specific testing approach for their verification and validation. This paper wants to investigate new research directions on mobile applications testing automation, by answering three research questions: (RQ1) are mobile applications (so) different from traditional ones, so to require different and specialized new testing techniques?, (RQ2) what are the new challenges and research directions on testing mobile applications?, and (RQ3) which is the role automation may play in testing mobile applications?. We answer those questions by analyzing the current state of the art in mobile applications development and testing, and by proposing our view on the topic.
