Abstract:
The software embedded in automotive control systems increasingly determines the functionality and properties of present-day motor vehicles. However, the development and test process of the software-based systems has become an ever more limiting factor. While these challenges, on the development side, are met by employing model-based specification, design, and implementation techniques, satisfactory solutions on the testing side are slow in arriving. With regard to the systematic test design and the description of test scenarios especially, there is a lot of room for improvement. This paper introduces the model-based black-box testing (MB3T) approach in order to effectively minimize these deficits by creating a systematic procedure for the design of test scenarios for embedded automotive control software and its integration in the model-based development process. The MB3T approach which has recently been successfully employed in a number of projects at DaimlerChrysler makes it possible to define test scenarios for software developed in a model-based way from different perspectives and also to create consistency between them.
