Fault-Based Test Case Prioritization of Regression Testing Using Genetic Algorithm

Abstract

Prioritization of test case technique schedules the test suite in an order which will increase the efficiency and effectiveness of the system. The test case executed in an order which enhances the probability of finding the fault and also it finds the severe fault at the early stage. The prioritization of test case is proved to be useful for the regression testing. While much research is going on code coverage based prioritization technique and requirement based test case prioritization technique is not used by many. In this paper, test case prioritization technique based on fault of regression technique is proposed from the requirement specification, to improve the software quality and to increase the fault detection rate. In this paper, test case prioritization is done based the six main factors (i) requirement based on customer priority (ii) based on changes made in requirement specification (iii) complexity in Implementation of code (iv) re-usability (v) flow of application (vi) impact of the fault.
