Dynamic Application Development for Web Application Process

JSP AND PHP applications are notoriously error-prone due to, e. g. , their state full, asynchronous, and event-based nature, the use of (loosely typed) JAVASCRIPT, the client-side requirement of the browsers Document-Object Model (DOM), and the use of delta communication between client and web-server. Unfortunately, static code analysis techniques are not able to reveal many of the dynamic dependencies present in todays web applications. To that end, we propose an implementation named ATUSA in which we automatically derive a model of the user interface states of an JSP AND PHP application by crawling the JSP AND PHP application code to identify key events and components. In order to recognize logical failures in these executions, we propose the use of invariants obtained from the crawling process and for handling structural failures we propose to implement Metamorphic Relations based oracle. The results highlight the efficiency of the proposed approach in terms of fault-detecting performances, reliability and scalability, automatic construction model and the usefulness of invariants and metamorphic relations.
