Testing Conformance of BPEL Business Process Based on Model Checking

Formalized analysis method is a technology that insures quality of software reliability. It can detect mistakes and flaws effectively in software design. Based on the research of model checking techniques for composition of web services, we establish an automatic test framework for web services composition of BPEL. Static test method is used and test cases are generated automatically in this framework. According to the input, outputs of cases and the requirement properties, we can test the conformance for business flow of BPEL. We analyze “Airline Tickets Reservation System” which is described by BPEL with our test framework and test the conformance of the system. In addition, we compare our method to model checking method which is used to verify web services composition from three areas including states stored, searching depth and consuming times. We can conclude that our method have a better efficiency when checking the web services which owns more states.
