Extended Regression Test Model for Test Suite Reduction

Problem of test suite size increases in the process of software maintenance when numbers of revision are required can be solved by reduction algorithms such random and regression test reduction. Nevertheless, the whole performance need to be improved. Therefore, this research paper proposes the new model that is used for improving the regression test reduction, which guarantees the best results compared with traditional methods by adding four algorithms; testing, ordering, deleting test cases and fixing bugs. Accordingly, it gives smaller size and higher percent fixing bugs as about 40% and 200% respectively.
