Abstract: Modern web-based applications are multitiered, distributed applications that typically run on heterogeneous platforms. Their correct operation depends increasingly on the interoperability of single software modules, rather than on their intrinsic algorithmic correctness. We present a scalable, integrated test methodology capable of granting adequate coverage of functional testing, yet still easy to use. It bases on our previous work on system level test of Computer Telephony Integrated applications, where our coordination-based coarse grain approach has been applied very successfully. The practicability of the approach is illustrated by testing complex role based functional features of our Online Conference Service, an advanced online management system for the organization of scientific conferences.

CV: He has worked at METAFrame Technologies GmbH as a consultant, where he has gained experiences in large OO-projects with UML and Java as well as in formal verification methods. During the last years he was the technical project leader of the project "Integrated Test Environment", where an innovative test environment for complex Computer-Telephony-Integrated systems was developed for Siemens AG. Currently he works as a research associate at the Chair of Programming Systems, Department of Computer Science, University of Dortmund.
