Multi-Paradigm Models as Source for Automatic Test Construction Victor Kuliamin ISP RAS, Moscow Why Multiple Models? Modeling Techniques OperationalCan be executed by virtual machine ContractPre- and postconditions, data integrity constraints History-basedConstraints on possible traces AlgebraicEquivalence between different execution histories Tasks of Testing Modeling Techniques Comparison Operational Contract History-based Algebraic Comparison Results There is no the best technique No one technique is good for everything May be a mix of different approaches can fit more needs? UniTesK Technology Model-based testing technology Developed in 2000 – 2002 in ISP RAS UniTesK Solutions Contract specifications of behavior FSM and LTS testing models Contract Specifications Preconditions and postconditions of interface operations and asynchronous reactions Data integrity constraints Close to requirements Suitable for oracle generation Provide low-level coverage criteria FSM and LTS Testing Models Define states and admissible input actions More abstract than original specifications Guarantee some low-level coverage Suitable for test sequence construction Provide high-level coverage criteria Relation between Models Whole Picture I Whole Picture II Tool Demo Set of Integers – Scenario I Mapping Abstract Call to Specific Set of Integers – Scenario II Failure References V.
