A PARADIGM FOR TESTING WEB APPLICATION

Abstract

For any work of literature, a fundamental issue is to identify the individual(s) who wrote it, and conversely, to identify all of the works that belong to a given individual or to identify the individual who writes many papers on same topic.

A web application is an application that can be accessed via a web browser over a network. Web applications contain client side code and server side code. Web applications undergo changes in the maintenance phase, and retesting changed programs is done thereafter. To retest a program after changes, we can select a subset of the whole test suite on the condition that the selected subset will give confidence about covering the changes. As an important method to ensure quality of web applications, Regression Testing techniques are required for adequate selection of these subsets of test cases. This project compares regression testing techniques for web applications based on a safe approach that covers changed elements and other potentially affected ones. In this project we have implemented a new technique to select test cases for regression testing on web applications based on the Edge Test Tree Graph (ETT) as presented in the paper “A Practical Web Testing Model for Web Application Testing” by Zhongsheng Qian, Huakiou Miao, Hongwei Zeng., School of Computer Engineering and Science, Shanghai University, China[5]. This work proposes a Web Testing Model for web application testing. It starts from constructing the ETT (Event Test Tree) of web application. An algorithm is designed to derive an ETT (Event Test Tree) from the EDG from ETT, we extract the path expressions to generate test paths. Then a test specification is made in C++ to generate the required test cases. Then the web application is modified and Regression Testing is applied. The regression test selection technique is based on identifying changed and potentially changed components. Empirical results show that this technique selects a reduced number of test cases that experience only affected and potentially affected components.we have also studied paper by Abbas Tarhini, Zahi Ismail, Nashat Mansour, Regression Testing Web Applications, 2008 International Conference on Advanced Computer Theory and Engineering[3].
