The importance of software is increasing dramaTIcally in nearly all sectorsof industry. In the area of business administraTIon, software has becomean indispensable core technology. Furthermore, more and more productsand innovaTIons are also based on software in most technical fields. A typicalexample is provided by the automoTIve industry in which a rapidly increasingnumber of innovations are based on electronics and software to enhance thesafety of the vehicles, and also to improve the comfort of the passengers and toreduce fuel consumption and emissions. In modern upper-class and luxury cars,20 to 25 percent of the cost is on electronics and software, and this proportionis estimated to increase to up to 40 percent in the next ten years.Software has a substantial influence on the quality of products as well as theproductivity of a company. Practice, unfortunately, shows that it is impossibleto develop a complex software-based system “first-time-right”. Hence, comprehensiveanalytical measures have to be taken to check the results of thedifferent development phases and to detect errors as early as possible. Testingconstitutes the most important analysis technique, besides reviews and inspections.It is, however, a very sophisticated and time consuming task, particularlyin the field of embedded systems. When testing embedded software, not onlythe software has to be considered but also the close connection to the hardwarecomponents, the frequently severe timing constraints and real-time requirements,and other performance-related aspects.This book should be regarded as an important and substantial contributionto the significant improvement of the situation in the field of testing embeddedsystems. It provides a comprehensive description of the world of embedded softwaretesting. It covers important aspects such as the testing lifecycle and testingtechniques, as well as infrastructure and organization. The authors’ concentrationon usability in industrial practice makes the book a valuable guide for anypractitioner. Due to the wide range of application of embedded software, thebook will be useful in many industrial businesses.
