The UDDI (Universal Description Discovery and Integration) provides classification to find the distributed Web Services (WS) by keyword matching. The UDDI version 3 allows searching WS using digital signatures. However, it still needs systematic verification to ensure WS quality in a timely fashion. This paper proposes adding verification mechanism to the UDDI servers including check-in and checkout of WS.

Testing is difficult and expensive, and testing distributed system even more difficult due to issues such as interoperability, collaboration, synchronization, timing, and concurrency. A tester often needs to spend significant time in developing lengthy testing code to ensure that the System Under Test (SUn is reasonably well tested. This paper proposes an Ollject-Oriented (00) framework to test distributed system rapidly and adaptively by using scenario modeling, state modeling, verification patterns, design patterns, regression testing, ripple effect analysis, simulation, automated test execution, and remote testing using TCPIIP or SOAP. Finally, this paper uses a supply-chain example to illustrate the key concepts.

This paper presents a process to develop adaptive object-oriented scenario-based test frameworks for testing embedded systems. Embedded systems often require rigorous testing due to the mission-critical nature of their applications, and they are often developed as a family of products. The process uses techniques such as design-for-change, design patterns, scenarios, ripple effect analysis, and regression testing. This paper then uses an example to illustrate this process by applying it to test a mobile phone system, and the framework constructed can facilitate generation of numerous test cases quickly with minimum effort, and it can also accommodates many changes suggested by another party without changing the overall structure of the framework.
