Basics and application trends for the testing and test control notation TTCN-3

Strong dependencies exist between innovations - standards and markets: Innovations influence standards and markets. Standards have impacts on markets and often are the basis for innovations. The market solutions are combined into standards. And new markets could be understood as an innovation. The testing technology TTCN-3 appears in all of these aspects. It is an established standard widely used in industry; it includes and brings up innovative concepts. This technology is evolving due to increasing industrial requirements and new research ideas. The roots of today's "Testing and Test Control Notation" (TTCN-3) started in the 80s. New tool and industrial test suite standards appeared shortly after its first publication by ISO. Initially used in telecommunication, today TTCN-3 i s applied for testing complex software in nearly all industrial domains. In particular, new application areas are automotive, medical, aerospace, and finance systems. TTCN-3 is a success story. Engineering departments of tool manufacturers and research institutes are using TTCN-3 as a target notation in the context of model-based testing. This year the European Standardization Institute (ETSI) has published several innovations that provide a standardized basis to the industry for innovative testing. Substantial work has been undertaken for "embedded TTCN-3" that includes real-time aspects and continuous systems. In the case of TTCN-3 the standardization bodies succeeded to create an engine for innovation and new markets. The tutorial provides the understanding of basic concepts t ogether with a presentation of latest concepts and new directions for the test technology TTCN-3.
