A VDM-based Approach for Specifying and Testing Requirements of Web-applications

The objective of this paper is to demonstrate the use of formal methods in a uniform way for functional as well as interface-requirements. We propose some add-ons to ‘Vienna Development Method Specification Language'syntaxes to cover the interface-requirements of a web-based application. We also propose a framework to support the transformation of the conventional SRS to a design specification, and a Finite State Machine based verification model, to test the design specification against the SRS.
