Test automation aims to reduce the cost and improve the effectiveness of software testing by using various techniques and methods. Other benefits are consistency and accuracy, reduction of overall test cycle time, risk mitigation of manual testing, and increase in overall product quality. Recording test activities as test scripts and playing the test scripts or record and playback are the common methods. More advanced methodologies include data-driven, keyword-driven and hybrid methods as well as framework-based methods. Among tool development, interoperability remains a major challenge. Theme of the Workshop: This year's theme of COMPSAC is "The Integration of Heterogeneous and Mobile Services in Smart Environments". The emergence and increasing importance of digital society, cyber-physical systems, and semantic, pervasive, and mobile computing are expanding the role of software and applications in smart environments. Associated with these paradigms are instruments, sensors, and a multitude of applications that generate and require analysis of massive volumes of diverse, heterogeneous, complex, and distributed data. The design of such intelligent systems is challenged by the complexity of the domains in which they are deployed. Accordingly, submissions including applications and case studies in these areas will highly be appreciated.
