Trends such as globalisation, standardisation and shorter lifecycles place great demands on the flexibility of the software industry. In order to compete and cooperate on an international scale, a constantly decreasing time to market and an increasing level of quality are essential. Software and systems testing is at the moment the most important and mostly used quality assurance technique applied in industry. However, the complexity of software systems and hence of their development is increasing. Systems get bigger, connect large amounts of components that interact in many different ways on the Future Internet, and have constantly changing and different types of requirements (functionality, dependability, real-time, etc.). Consequently, the development of cost-effective and high-quality systems opens new challenges that cannot be faced only with traditional testing approaches. New techniques for systematization and automation of testing are required. Even though many test automation tools are currently available to aid test planning and control as well as test case execution and monitoring, all these tools share a similar passive philosophy towards test case design, selection of test data and test evaluation. They leave these crucial, time-consuming and demanding activities to the human tester. This is not without reason; test case design and test evaluation are difficult to automate with the techniques available in current industrial practice. The domain of possible inputs (potential test cases), even for a trivial program, is typically too large to be exhaustively explored. Consequently, one of the major challenges associated with test case design is the selection of test cases that are effective at finding flaws without requiring an excessive number of tests to be carried out. This is the problem which this workshop wants to attack. This workshop will provide researchers and practitioners a forum for exchanging ideas, experiences, understanding of the problems, visions for the future, and promising solutions to the problems in automated test case generation, selection and evaluation. The workshop will also provide a platform for researchers and developers of testing tools to work together to identify the problems in the theory and practice of software test automation and to set an agenda and lay the foundation for future development.
