  1. Project Overview Wolfgang Herzner / ARC smart systems

  2. Objectives • To significantly enhance testing and verification of dependable embedded systems • by means of automated generation of efficient test cases • relying on development of new approaches as well as innovative integration of state-of-the-art techniques Goal: reduce testing effort by at least 20% • To address both testing of • functional safety tests • and non-functional issues like reliability, e.g. by system stress or overload tests • To apply these technologies in large industrial systems, • simultaneously enabling application domain experts (with rather little knowledge and experience in usage of formal methods) to use them with minimal learning effort

  3. MOGENTES – demonstrators • Automotive • Off-highway • Railway signalling User Requirements Specification Test Case Application (unit, system, SIL, HIL, FI) Software / System Constructoir Destructi f1(xd, fs nnm) isOpen() Constructoir Destructi f1(xd, fs nnm) isOpen() Constructoir Destructi isOpen() Safety Requirements(Standards) Test CaseGeneration Result Data Test Cases Scenario MOGENTES – research core (Fault)Model

  4. Application Demonstrators • Automotive • Test cases for HIL • Off-highway vehicles • Implement-control (bucket) through human driver(ISOBUS-conform) • Railway interlocking • (stress) tests for signalling and interlocking control system • verification of peripheral signals analyser (of electronic rail control desk)

  5. Approach (Aspects considered) • Common modelling languages and semantics • for domain specific requirements and (partial) models of the demonstrators • Test theory(/ies) • conformance relation between the model and implementation • notion of success and failure of a test case • Fault models • extending modelling languages • Coverage criteria • Model-based fault injection (MBFI) • Validate the defined fault models (and thus the generated test cases) with physical fault injection • Framework • semantics-aware transformations • from system models to inputs of specific tools, • to interface with existing simulation/test environments from industrial partners
