The 2nd International Workshop on Requirements Engineering and Testing will be held in conjunction with the 37th International Conference on Software Engineering (ICSE 2015) in Florence, Italy, on Monday, May 18 2015. Requirements Engineering and Testing are both important areas within software engineering, each with their research communities and set of practitioners. The coordination of these two fields affects the efficiency and the effectiveness of the entire software development cycle and its lead time, making this an important topic from a business perspective. While much work has been done in the respective fields of Requirements Engineering (RE) and Testing, there exists much more that can be done to increase the connection between the RE and the Testing process. The objective of this workshop is to address the interplay of Requirements Engineering (RE) and Testing, in research and industry, including the challenges that come with connecting requirements and testing. The goal of this workshop is to highlight the importance of this cross-disciplinary research area and to develop a body of knowledge for RET. The first workshop (held in conjunction with the IEEE International Requirements Engineering Conference 2014) produced a map of the area of RET including 20 topics covered by this new research area. This map includes topics that are related to processes, practices, artefacts, methods, techniques, tools and softer aspects like the communication between roles in the software engineering processes. The workshop aims to provide a dedicated forum for exchanging ideas and best practices and to foster industry-academia collaboration on this topic. In this way, the workshop connects the (currently) separate communities of RE and Testing.
