Software systems is evolve continuously during development and maintenance. After software is modified regression testing is applied to software to ensure that It behaves intended and modifications not negatively impacts its original functionality. It is time consuming to rerun test suite T of program Pi on modified program Pi+1. So, there are many regression testing techniques are there for doing regression testing. These are based on coverage data. So, computing coverage data for Pi+1 without rerunning all test cases is the problem for doing regression testing of program Pi+1. This paper proposed a new approach that computes coverage data with selecting test cases T' for the subsequent versions of the software.
