The purpose of this paper is to define an effective strategy for Regression Testing for complex Telecom Systems wherein the changes going into each release are high. The complexity of the Telecom Systems is growing day by day and whenever there is a new feature or enhancement going into the product, there is a need to ensure that the legacy functionality was not broken. This is being achieved through Regression Testing. With increase in the number of versions of the product, Regression Testing becomes tedious and costlier as there is significant increase in the number of Test Cases in the Regression Suite. Through this paper, the authors attempt to create a Test Strategy that optimizes the regression Test Cases without loosing the focus of Regression testing. This does not mean the elimination of Test Cases in order to shorten the overall test cycle and reduce the cost. This strategy gives a smart solution to build an optimized and effective Regression Suite.
