Test case prioritization technique based on early fault detection using fuzzy logic

Regression testing is time consuming and expensive activity in software testing. In Regression testing when any changes made to already tested program it should not affect to other part of program. Regression testing is crucial activities in software testing and maintenance phases. If some part of code is altered then it is mandatory to validate the modified code. Throughout regression testing test case from test suite will be re-executed and re-execution of all the test case will be very expensive. In this paper we present regression test case prioritization for object oriented program. The most important research is how to select efficient and suitable test cases during regression testing from the test suite. To minimize the regression testing cost we have applied prioritization technique. In this paper prioritization is done based on fault detection rate of program, execution time and requirement coverage using fuzzy logic.
