Abstract: A computer-implemented method for recording and replaying user sessions in browser based applications includes initiating a user session as a result of a user accessing an application in a web browser. The computer-implemented method also includes attaching an event handler to the application as a replacement for an original event handler. Further, the computer-implemented method includes executing the event handler in response to an event, wherein the event is a plurality of user actions performed during the user session. Furthermore, the computer-implemented method includes receiving the plurality of user actions as inputs to the application. Moreover, the computer-implemented method includes recording the plurality of user actions and replaying the plurality of user actions recorded at a later time.
