A Review on Regression Testing of Object Oriented Programs

Regression testing plays a vital role for software maintenance when software is modified. The main purpose of regression testing is to ensure the bugs are fixed and the new functionality that are incorporated in a new version of a software do not unfavorably affect the correct functionality of the previous version. So to revalidate the modified software, regression testing is the right testing process. Though it is an expensive process which requires executing maintenance process frequently but it becomes necessary for subsequent version of test suites. In the context of object oriented software‟s large scale application, regression testing for object oriented software find its demand in industry and research in a wide form. In this paper, we have discussed about the regression testing of object oriented programs and how it is being used and also We have a discussion about regression test selection algorithm used for object oriented program especially for C++ programs.
