Candidate analysis of change impacts on the web application

Abstract

Web-based applications will generally change due to bugs, new requirements, fresh environmental migration, or structural changes as part of software evolution. Continuous changes to web applications cause the program to become bigger and more complicated, so it makes difficulties in identifying which parts of the app will be changed. This study propose a technique of impact analysis in the candidate impact set stage in web application of Java-based. This technique can identify different source code file between web pages and typed of class. Source code of application will transform to intermediate format and then to object-oriented data dependency graphs format before doing identify. Identify source code take on program structure has transform based on request of change. The analysis of the impact of these changes produces the set of candidates affected by the change. The prototype is built to test candidate impact analysis results in Java web applications. Testing with case studies shows the technique can analyze the impact of program code changes on Java-based web applications.
