Tools for Anomaly and Failure Detection in Web Applications

Web applications have become crucial components of our life. However, research studies claim that the experienced quality and reliability of Web applications is often poor or not satisfactory. Evaluation tools are expected to give an important contribution to the improvement of Web applications. Unfortunately, the functionalities offered by available (commercial and research) tools are often limited. Aim of our previous work was to define and implement two tools (ReWeb and TestWeb) able to provide some novel, interesting analyses and testing techniques. In this paper, ReWeb and TestWeb are presented and used to find some anomalies and failures in four case studies. At the end of the paper a list of analysis and testing tools for Web applications is considered and confronted with ReWeb and TestWeb
