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 derive executable tests within the Testing and Test Control Notation (TTCN-3) is discussed. The transformation rules between the source U2TP meta-model to the target TTCN-3 meta-model are given.

1 Validation as opposed to verification means to check user requirements of systems and services with sampling techniques such as testing and not with mathematical proofs.

Abstract. Over the past years, the scope of telecommunication services has increased dramatically making network infrastructure-related services a very competitive market. Additionally, the traditional telecoms are combined with Internet technologies for providing a larger range of services. The obvious outcome is the increase of the number of subscribers and services demand. Due to this complexity, the performance testing of continuously evolving telecommunication services has become a real challenge and requires efficient and more powerful testing solutions. This ability highly depends on the performance test design and on the efficient use of hardware resources for test execution.This paper proposes a performance testing methodology which copes with the characteristics mentioned above. The methodology consists of a set of methods and patterns, exemplified for the TTCN-3 language, to realize adequate performance tests for multi-service systems. The effectiveness of this methodology is demonstrated throughout a case study on IP Multimedia Subsystem (IMS) performance testing.
