A Comparative Study of Five Regression Testing Techniques A Survey

ABSTRACT Regression testing is a style of testing that focuses on retesting after changes are made. In traditional regression testing we reuse the same tests the regression tests. Over the years numerous regression test optimization techniques have been described in the literature. Empirical studies of the techniques suggest that they can indeed benefit testers but so far few studies have empirically compared different techniques. In this paper the results of a comparative empirical study of five different regression test optimization techniques are represented. The comparison is based on different qualitative and quantitative criteria such as number of tests selected execution time of tests precision user parameters global variables handling type of testing etc. These algorithms are found to be suitable for different requirements of regression testing.
