Abstract: “Regression testing is a costly and time taking affair. Because of time and resource constraints it is not possible to run all the test cases of the regression test suite. Prioritization of test cases provides a way to run highest priority test cases in the first phase. It helps to improve the percentage of fault detected in given time and is found to work better with feedback mechanism. History Based approach is one of the methods to prioritize the test cases based on the feedback of each test case. The feedback for each of the test cases is obtained from the history of each of the test cases in terms fault detection, number of executions and other such factors. This paper proposes the prioritization of test cases for the modified lines of code. The results establish that number of sessions required for running the test cases reduces by almost 33%.”
