Web Application Record-Replay System and Method

A web application includes a record-replay library component to record sessions into a log file and subsequently replay the recorded session based upon the log file. The record-replay library interacts with the runtime environment of the web application to intercept events that correspond to data inputs received by the web application, such as user inputs, remote server inputs and inputs from the computer system on which the runtime environment is executing. On replay, the log file is read by the record-replay library and events are programmatically dispatched to the runtime environment by the record-replay library based on the log entries in order to simulate the various data input events that occurred during the recorded session.
