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 per-formace 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)
Assembling new software systems from prefabricated components as an attractive alternative to traditional software development practices is more and more investigated. Component technologies like CCM, .Net or EJB are accompanied by model-based approaches like MDA. However, still the emphasis is rather on system design and development and not on system(More)
