A new approach for session-based test case generation by GA

User-session-based testing which relies on capturing and replaying real user sessions is an effective approach to test web applications. However, as a black-box testing, test case generation totally based on user session data may not be qualified for ensuring the reliability of web applications. This paper proposes an approach named US-RDG in terms of gray-box testing, combining User Session data with Request Dependence Graph (RDG) of web application, to automatically generate test cases with the using of GA. Simulation results indicate that US-RDG effects better than the traditional user-session-based testing, and attains higher path coverage and fault detection rate within small size of test suite.
