Model-based test-case generation for Simulink/Stateflow using dependency graph approach

Abstract

Testing is an ultimate phase of product life cycle to which particular attention is paid, namely when dependability is of great importance. Modeling technology has been introduced into the software testing field. However how to carry through the testing modeling effectively is still a difficulty. Based on the combination of simulation modeling technology and dependability we have proposed an approach to generate test cases. In our approach, first, the system is modeled in MATLAB using Simulink/ Stateflow tool. After the model creation we verify that system and generate a dependency graph of that system. From that graph we generate test sequences.
