Testing web service's compositions following TASSA methodology

Abstract

Service compositions are increasingly used for the fast development of loosely-coupled dynamic distributed applications. Providing their quality is a challenging task due to various problems at infrastructure, service and orchestration levels as well as necessity of performance of different types of testing in unknown context and environment. This paper proposes a methodology for testing web service compositions, described with Business Process Execution Language for Web Services (WS-BPEL). Its feasibility is proved through a case study, showing how the methodology's steps can be performed though automated tools in order to achieve functional, performance and robustness testing.
