Aspect Orientation Based Test Case Selection Strategy for Service Composition

Software testing is an important part of software maintenance, but it can also be very expensive. To reduce this expense, software testers may select part of their test cases so that those that are more important are run earlier in the testing process. However, the methods that can be used to select test cases for service composition and its analysis are still lacking at present. This paper proposes an aspect orientation based test case selection strategy for service composition. Aspect-orientation is used to weave testing crosscutting concerns of service composition, which includes component testing concern and testing concern of service composition, the weaving mechanism dynamically integrates these schemas into a testing enforcement model. Based on this, the test cases selection strategy for service composition is given, and abstract it as a crosscutting concern to weave into testing model, the corresponding enforcement algorithm is also given, the operation semantics and related theories of Petri nets help prove its effectiveness and feasibility. A case study explains the testing process of service composition, and a series of experiments are done to explain that the use of aspects for testing Web service is more efficient than conventional techniques, which can improve the testing quality and efficiency.
