Interoperability testing of web services for e-learning

Web Services technologies seem to open interesting unexplored scenarios in the e-Learning domain. Particularly appealing is the possibility of defining and standardizing Services that when implemented and composed, will result in complex e-learning applications. However an agreed standard specification per se is not sufficient, rather methodologies for validating conformance against it must also be released. This paper discusses current approaches standardise Web Service specification and implementation and outlines an approach to conformance verification of services through testing, aiming at reducing the risk of interoperability issues at execution time.
