The paper “Interactive Record/Replay for Debugging Web Applications” by CSE’s Brian Burg, Jake Bailey, Amy Ko, and Michael Ernst has received a Best Paper Honorable Mention from UIST 2013.
The paper describes Timelapse, an extension to the WebKit browser engine that can cheaply capture and exactly replay a user’s session with a web application. This capability is being used to create powerful new tools for debugging, testing, bug reporting, and program visualization.
