The approach towards system engineering according to Model-Driven Architectures (MDA) with code generation derived from model implies also an increased need for research on automation of the test generation process. This paper presents an approach to derive executable tests from UML 2.0 Testing Profile diagrams automatically. In particular, an approach to(More)
System-level testing considers functionality and load aspects to check how a system performs for single service requests and scales as the number of service requests accessing/using it increases. This paper presents a flexible test framework including functional, service interaction and load tests. It is generic in terms of being largely independent of the(More)
This paper describes a benchmarking workload model for business process execution language (BPEL) engines for Web services. The proposed model is based on simulation of real world traffic conditions by defining a set of requirements which best characterize the end-users. The performance characteristics are evaluated on top of collected measurements such as(More)
Similar to software development, the test development must be accompanied with a set of rules specifying how to write tests. They are grouped together into a document called guideline. Guidelines are especially necessary for large test specifications involving many developers and have the goal to reduce the effort of the overall development. So far, no(More)
GuiGen is a comprehensive set of tools for creating customized graphical user interfaces (GUIs). I t draws from the concept of computing portals, which are here seen as interfaces to application-specific computing services for user communities. While GuiGen was originally designed for the use in computational grids, i t can be used in client/server(More)
The design of TTCN-3 focused on extensions to address testing needs of modern telecom and datacom technologies and widen the applicability to many kinds of tests including performance tests. One of the most important features of TTCN-3 is the platform independence which allows testers to concentrate on the test specification while the complexity of the(More)
