COST EFFECTIVE REGRESSION TESTING

Regression testing is costly and frequently used testing it used for modifying the software. In Regression testing also ensure that changing portion does not effect on unchanging portion. In other way , we can say that regression testing is also a software development process. It is critical part of software maintenance. it occupies a large portion of budget in the maintenance that means the regression testing is costly testing and frequently needed this testing to do changes in a software. Basically if we want to reduced the cost of regression testing so easily and comfortably we can modify our softwares.In this paper, we are planning to propose an enhanced regression test selection method in black-box environment which reduces the regression testing cost using ETL technique. Also we are using this technique in different databases. General Terms Regression testing, ETL technique, Data warehouse, Black box testing
