Software testing is very crucial process which helps in finding errors. The aim of web application testing consists of executing the application using combinations of input and state to reveal failures [2]. There are a number of testing techniques which serve different purposes though it is impossible to find and correct all the errors. Software testing of a web based application is done so that the performance and quality of the web based application remain up to the mark so as to meet the user?s requirement. In this paper, the stress testing on the web based application is done so as to calculate the load on the web based application. The web based application is put under a lot of stress often to breaking point so that the stability of the web based application could be judged. This is done by attaching the JavaScript code to the web page or the web based application whose stress needs to be tested. The results are stored in the database for future reference.
