  1. WP4Algorithms, Tools and Fault Injection Mutation-Based TCG (D4.3) Bernhard K. Aichernig, TUG

  2. WP4 - Objectives • Model-Based Mutation Testing Tools • UML, Action Systems • Simulink

  3. D4.3 Progress • Tools: • Ulysses • Ioco checker implemented in Sicstus Prolog • Mutation testing of Action Systems • Hybrid Systems! • Model animator • Argos • OOAS to AS translator implemented in C# • Rich types: lists, list-comprehension, sets, quantors • Type checking • Model checking via CADP translation • Model animator • Cover (ETH) • Mutation Testing with CBMC for Simulink models

  4. D4.3 Progress • Tool validation • Ulysses can produce complete LTS • ioco check of two equivalent models • Argos can produce complete LTS • via CADP interface • Simplify and check bi-similarity in CADP • Model validation (UML, OOAS, AS) • Step-wise animation of Actions • In Argos and Ulysses • Model checking • mu-calculus checks in CADP

  5. D4.3 Progress • Publications • Willibald Krenn and Bernhard Aichernig. Test case generation by contract mutation in Spec#.

  6. Hybrid Systems Testing in Ulysses • When the water level inT2 decreases below Reserve, pump P1 delivers water to T2. • When T2 is Full or T1 gets Empty pump P1 is turned off. • The inflow into T1 is external to the system. • Pump P2 is controlled by a user. • d/dt(x1) = (flowIn – flowP1) / A1 • d/dt(x2) = (flowP1– flowP2) / A2
