Abstract
E-business systems are known for their frequent changes in business requirements, and traditional software development engineering approaches have difficulties in keeping up with this dynamicity. The use of service oriented architecture in software development has become popular as it provides a solution to frequent changes to business environments in a heterogeneous network. In service oriented architecture, new systems are quickly developed by combining services developed and owned by different organizations, and one way of realising this architecture is via Web services. Although much research effort has been put into the discovery, invocation and composition of services testing Web services has only begun to attract interest from both researchers and industry players. This paper aims to provide a mapping study of current Web services composition testing researches conducted by other researchers. Research papers on testing of Web services composition were gathered from various scholarly databases using provided search engines within a given period of time. The research papers were then classified according to issues addressed by them. The aim is to get a broad overview of the current state of research in Web services composition testing. By looking at the areas focused by existing researchers, gaps and untouched areas of Web services composition testing can be discovered.
