The testing and debugging of applications within a SOA presents special challenges. A defect observed at the level of user interaction with the application could be: (1) a fault (performance, security, scalability, etc.) in the application or process logic; (2) a fault in any of the services used by the application; (3) an unintended interaction in combining services. The key challenge to be faced is how to ensure that organizations can manage the complexity of their composite applications and service-oriented architecture in a manner that addresses the engineering requirements of testing while providing tools that are efficient, productive, and reasonable for testers to learn. In our thesis we address these issues by introducing a 'grey box' test agent architecture and a model-driven approach to express 'grey box' test campaigns.93 p.enComputer Science.Thesis
