State aware test case regeneration for improving web application test suite coverage and fault detection
Abstract
This paper introduces two test cases regeneration approaches for web applications, one uses standard Def-Use testing but for state variables, the other uses a novel value-aware dataflow approach. Our overall approach is to combine requests from a test suite to form client-side request sequences, based on dataflow analysis of server-side session variables and database tables. We implemented our approach as a tool SART (State Aware Regeneration Tool) and used it to evaluate our proposed approaches on 4 real world web applications. Our results show that for all 4 applications, both server-side coverage and fault detection were statistically significantly improved. Even on relatively high quality test suites our algorithms improve average coverage by 14.74% and fault detection by 9.19%. © 2012 ACM.
