The objective of RET is to explore the interaction of Requirements Engineering (RE) and Testing, in research and industry, and the challenges that result from this interaction. While much work has been done in the respective fields of requirements engineering and testing, there exists much more than can be done to understand the connection between RE and testing processes. We hope RET will provide a much needed forum for exchanging ideas and best practices for aligning RE and testing, and in particular can help foster industry-academia collaboration on this topic. Accordingly, we have planned to invite an industry keynote and conduct an interactive session to map the research area, along with traditional presentations of accepted papers. RET expects submissions exploring how to best align RE and testing. This can include processes, practices, artifacts, methods, techniques, tools and softer aspects like the communication between roles in the engineering process. Submissions can vary from short position papers outlining observed problems, to short papers employing case studies, experiments, experience reports, etc. We particularly encourage submissions from industrial practitioners or those working with industrial partners.
