An Effective Approach to Regression Test Optimization Technique

Unswerving product quality is the main goal of any software engineering product. It involves rigorous product development and testing. Whenever new features are introduced to any existing product, the stress on quality is more, which will have more effect or impact on the ‘regression’ testing phase, in which all older functionality of the product are tested to make sure that the older functionality is intact. With an age, the product will have more features and will become more complex to choose regression test cases for such a complex products, if we don’t have any regression optimization technique in place. Such situation will have direct impact on delivery and schedule of the product. Hence, in this paper we propose a new technique by which we can reduce the regression test phase by using a variety of inputs to determine the appropriate smaller number of test cases out of entire large test suite.
