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)
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). It 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, it can be used in client/server(More)
