A model driven approach toward business process test case generation

Web service based business process has become the backbone of enterprise information system, and it is evolving all the time. Therefore, the process has to be tested thoroughly and repeatedly whenever it is changed. This paper proposes a model driven approach toward generating executable test case from the given business process. The approach is composite of three stages: defining a process under test based on the business process model, transforming from process under test to abstract test cases and from abstract test cases to executable test cases. To implement the approach, a business process model based on the BPEL specification and UML2.0 activity diagram and a test case model based on U2TP framework and TTCN-3 key concepts are defined to have the ability to define the business process and the abstract test case. In order to validate the approach, a loan request process is used to show how the approach work and how the test cases are generated.
