Prioritizing the Test Cases of Web Services by APFD Metric

Regression Testing is a major component of most major testing systems but has only begun to be applied to Web services. A number of different approaches have been studied to maximize the value of the accrued test suite: minimization, selection and prioritization. Test suite minimization seeks to eliminate redundant test cases in order to reduce the number of tests to run. Regression test selection optimizes the regression testing process by selecting a subset of all tests, while still maintaining some level of confidence about the system performing no worse than the unmodified system. Test case prioritization seeks to order test cases in such a way that early fault detection is maximized.
