Abstract

Regression testing of web applications is a costly activity as it tends to generate more test cases than the previous stages of software testing. This cost can be reduced significantly by identifying and testing only the modified parts of a web application. This will require locating the changes that have been introduced in the web application from the previous version that was tested. In this paper we have introduced an automated tool for locating the changes in the web application which will thereby aid in effective regression testing of the application. This tool compromise of 3 parts, a) a web crawler that crawls the web application, b) an HTML DOM tree generator that generates the DOM tree for a specified web page, c) an comparator that compares the new DOM tree with a previous version of the DOM tree stored in our system.
