Model-Driven Testing based on Markov Chain Usage Models in the Automotive Domain

Résumé

The Extended Automation Method (EXAM) is employed by AUDI AG - one of the leading car manufacturers in Europe - to design and execute test cases for the purpose of component and system-testing. Test cases are specified using platform independent UML sequence diagrams. In order to provide an executable test suite platform dependent code is automatically generated from a formal description. The test case execution itself is mainly performed on Hardware-in-the-loop (HIL) simulators. The main drawback of the existing procedure in EXAM is correlated to the fact that each test case must be created individually, which is apparently awkward and error-prone. Furthermore the development of increasingly complex and interconnected features poses new challenges to the prevalent validation and test routines in the industry. We therefore have evaluated whether the appliance of a Markov Chain Usage Model (MCUM) would help to overcome this drawback. The MCUM was used to describe at best all possible usage scenarios of the System Under Test (SUT) and provided a basis to derive systematically test cases without human interaction. These test cases can be further processed inside EXAM. This approach makes it also possible to get both indicators for the test-planning in advance and to obtain dependability measures after the test cases have been processed. The usage of MCUMs in a fully automated process has been demonstrated within the QoS Enhanced test Development (Q.E.D.) test framework. In addition, the automotive domain requires a variety of problems to be resolved
