Context-driven testing approach for composability of simulation model

Testing is an important aspect in effectiveness verification of the composability of simulation model. This paper introduces a context-driven testing approach that supports to confirm and improve the composability of model in composable simulation research. Context-driven testing is a feasible approach that specifies model test framework and algorithms of constraint modeling for test on three hierarchical phases. On the system phase, taking the basic task as testing element, model test judges the satisfactory of composed simulation model’s behavior to the real requirements. On the component phase, taking interaction between models as testing element, model test judges the correctness of interactions depending on match degree between event expression and real event sequence. On the element phase, taking internal behavior of entity as testing element, model test analyzes the causes that make test condition dissatisfied on the system phase and component phase. The context-driven testing approach supports conformation of model composability powerfully.
