Regression Testing Using Fuzzy Logic

Regression testing is an immensely important process in the maintenance phase. The prioritization of test case becomes all the more important owing to the fact that it is not feasible to run all the test cases after each and every change. The proposed work dwells on the power of fuzzy expert system to make decisions which are better than the normal expert systems. The technique uses concepts like defect impact and coverage for test case selection. The work intends to propose a new framework for a fuzzy expert system based regression testing technique. The proposed architecture enhances the existing fuzzy logic based technique and removes faults therein. The proposed system architecture has been designed and initial results are encouraging. The system is poised to prove pivotal in the discipline. Keywords—Regression testing, prioritization, fuzzy expert system, coverage, defect impact.
