Model Checking the World Wide Web
Web design is an inherently error-prone process. To help with the detection of errors in the structure and connectivity of Web pages, we propose to apply model-checking techniques to the analysis of the World Wide Web. Model checking the Web is different in many respects from ordinary model checking of system models, since the Kripke structure of the Web is not known in advance, but can only be...
متن کاملRewriting-based Verification and Debugging of Web Systems
The increasing complexity of Web system has led to the development of sophisticated formal methodologies for verifying and correcting Web data and Web programs. In general, establishing whether a Web system behaves correctly with respect to the original intention of the programmer or checking its internal consistency are non-trivial tasks as witnessed by many studies in the literature. In this ...
متن کاملDebugging of Web Applications with Web-TLR
WEB-TLR is a Web verification engine that is based on the well-established Rewriting Logic– Maude/LTLR tandem for Web system specification and model-checking. In WEB-TLR, Web applications are expressed as rewrite theories that can be formally verified by using the Maude built-in LTLR model-checker. Whenever a property is refuted, a counterexample trace is delivered that reveals an undesired, er...
متن کاملDiagnostic Model-Checking for Real-Time Systems
Uppaal is a new tool suit for automatic verification of networks of timed automata. In this paper we describe the diagnostic model-checking feature of Uppaal and illustrates its usefulness through the debugging of (a version of) the Philips Audio-Control Protocol. Together with a graphical interface of Uppaal this diagnostic feature allows for a number of errors to be more easily detected and c...
متن کاملDebugging of Markov Decision Processes (MDPs) Models
In model checking, a counterexample is considered as a valuable tool for debugging. In Probabilistic Model Checking (PMC), counterexample generation has a quantitative aspect. The counterexample in PMC is a set of paths in which a path formula holds, and their accumulative probability mass violates the probability threshold. However, understanding the counterexample is not an easy task. In this...
