Abstract: |
Regression testing is an important activity in the process of software testing. It is applied after a program is modified to detect whether new errors have been introduced into previously tested code and provide confidence that modifications are correct. Since regression testing involves testing the modified program with the old test cases and is an expensive process, researchers have proposed regression test selection techniques as a way to reduce some of this expense. Through analyzing the drawbacks of existing regression testing techniques, in this paper, we present the RTCSFD (Regression Test Cases Selection based on rate of Fault detection and Design information), a new method for regression testing, which takes fault detection and test suite design information into account. This approach attempts to reduce costs by selecting and running only a subset of the test cases in a program’s existing test suite. Preliminary experiment has been employed on a system, and experiment results show that the method of regression testing case selection is feasible and effective in practice. Compared with existing method, the new method can make use of design information and perform test case prioritization, and is more efficient in detecting faults.
