COMPLIANCE TESTING OF OPEN SOURCE SOFTWARE FOR WEB PROCESSING SERVICES
For geospatial applications the OGC establishes standards for instance for Web Service interfaces. Based on these Web Service interfaces, client applications are able to retrieve particular functionality, such as GIS functionality provided by the Web Processing Service. Unfortunately, these standards maybe interpreted differently by different software vendors, thus different software packages might behave differently, although the requests are similar. So the software packages are intended to be equal, but practice might show a different result. To evaluate the compliance of software packages according to a specific standard, compliance testing is essential. The Web Processing Service is one of the standards, which is currently implemented as a server or client solution by different vendors and available as Open Source software. Compliance testing for WPS servers and clients however, has not been performed yet. Therefore, this talk will demonstrate the results of the compliance testing of WPS server and client implementations available as Open Source software. In particular, a pairwise compatability check will be performed with: The results of these tests are essential for future development of interoperable WPS implementations and will act as a benchmark for upcoming releases. Overall, this will improve the sustainablity of Open Source software development.
