The objective of our work is to create an open-source, extensible, freely available tool that web application testers can use to visualize the differences in the returned HTML results from executing web applications. The tool thus eases the burden on web application testers to locate faults.
More information about our project and current publications can be found on the HiperSpace Website under Publications of Current projects: Web Application Testing.
Our development of a tool for web application testers prompted further development in the oracles we execute when analyzing two different HTML responses. My role has been to improve a current oracle we have that involves structural analysis.
