Tools and Techniques Used for Prioritizing Test Cases in Regression Testing

Abstract

Testing is a very expensive task in term of cost, effort and time and it is necessary step of software development because without testing software cannot be completed. Regression testing is a type of software testing which is widely used in software development and maintenance phase; it also occupies a large portion of the software maintenance budget. There are many software testing tools and Technique that is used to test the software program. This research paper defines some testing approach which reduced person effort and time in regression testing. Software systems are change regularly during development and maintenance face. After software is modified regression testing is applied to software to ensure that it behaves intended and modifications not negatively impacts its original functionality. This paper focus on improving the performance of regression testing by using these approach for regression testing by computing coverage data for evolving software using dataflow analysis and execution tracing .
