Model-based testing of distributed functions

The standard-compliant development of component-based embedded systems calls for systematic coverage of product requirements and for testing component interactions at the system integration stage. System functionality is represented by a set of complex distributed functions, i.e., functions that are spread across several system components. This chapter presents a novel automated modelbased testing approach for distributed functions that uses informal system requirements and component behavior models. The test modeling notation makes it possible to model component interactions and composite functions with defined pre- and post-conditions. Test cases are automatically generated as scenarios of distributed functions represented by sequences of component interactions.
