System testing and validation is an area which has been the focus of many research efforts for decades. Yet, due to new challenges resulting from new development processes, such as SCRUM used in agile development and new aspects of large scale system integration, the need for efficient testing has been seeing much resent research. That is why this workshop will bring together researchers and practitioners in the field of system testing and validation. The goal of the workshop is to provide a forum for presenting and discussing work in progress, or ideas for future research in response to future trends.The workshop will be Tuesday 10 October 2017 hosted by Fraunhofer FOKUS (Berlin) the day before
the 5th UCAAT, together with INTUITEST. We like to encourage all STV17/INTUITEST participants also to attend the 5th UCAAT. This year STV is supported by the research projects UTEST, PREVENT and IoT-T.
