An Automatic Test Case Generation Framework for Web Services

— BPEL (Business Process Execution Language) as a de-facto standard for web service orchestration has drawn particularly attention from researchers and industries. BPEL is a semi-formal flow language with complex features such as concurrency and hierarchy. To test a model thoroughly, we need to cover different execution scenarios. As is well known, it is tedious, time-consuming, and error prone to design test cases manually, especially for complex modelling languages. Hence, it is desirable to apply existing model-based-testing techniques in the domain of web services. We proposed WSA (Web Service Automata) to be the operational semantics for BPEL. Based on WSA, we propose a model checking based test case generation framework for BPEL. The SPIN and NuSMV model checkers are used as the test generation engine, and the conventional structural test coverage criteria are encoded into LTL and CTL temporal logic. State coverage and transition coverage are used for BPEL control flow testin...
