Using chemical reaction optimisation for test case minimisation problem

The software is modified several times. In regression testing, it is ensured that these modifications in the software never affect the software negatively. The modifications to the software also create new test cases due to the addition of new functionality. These modifications or versions of the software make the test suit size growing over time. Again, re-testing of all the test cases is practically impossible. To avoid re-test all (testing all the test case again), regression test case minimisation (TCM) plays a vital role by reducing the size of the test case. TCM problem is one of the major regression testing problems, which can reduce the cost of regression testing by reducing the size of test case pool. This paper searches the possibility of applying chemical reaction optimisation (CRO) to solve TCM. The developed algorithm is tested with object oriented program of a different line of code (LOC). The simulation results indicate that this algorithm gives an outstanding performance to reduce the test cases and saving object oriented software cost. This reduces test case containing redundant free test cases without compromising on their overall effectiveness.
