A Subsumption Hierarchy of Test Case Prioritization for Composite Services


Several composite workflow services utilize non-imperative XML technologies such as WSDL, XPath, XML schema, and XML messages. Regression testing ought to assure the services against regression faults that seem in both the workflows and these artifacts. During this paper, we have a tendency to propose a refinement-oriented level-exploration strategy and a multilevel coverage model that captures progressively the coverage of different types of artifacts by the take a look at cases. We have a tendency to show that by using them, the test case prioritization techniques initialized on high of existing greedy-based mostly take a look at case prioritization strategy type a subsumption hierarchy such that a technique will produce a lot of test suite permutations than a method that subsumes it. Our experimental study of a model instance shows that a technique typically achieves a better fault detection rate than a subsumed technique, which validates that the proposed hierarchy and model have the potential to improve the price-effectiveness of check case prioritization techniques.
