A systematic framework for evaluating hyperlink validity in Web environments

In nowadays, the technical complexities of a Web site and variances to the browser make Web testing and quality control much more difficult. This paper investigates the quality issue of the Web systems and a systematic framework for Web testing is proposed, in which a Web application model is established to denote all components of a Web site by the Markov usage chain. To demonstrate its usability, a practical example of link validity testing is presented. The suggested validation mechanism not only generates automatically a complete set of the test scripts for link validation, but also provides quantitative analysis of the invalid components in a Web application.
