Regression Testing Web Applications

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. Regression testing techniques are required for adequate selection of these subsets of test cases. This paper presents a new regression testing technique for web applications based on a safe approach that covers changed elements and other potentially affected ones.
