![]() With its rich combination of technologies, Ajax provides a strong foundation for creating interactive web applications with XML or JSON-based web services by using JavaScript in the browser to process the web server response.Ajax Design Patterns shows you best practices that can dramatically improve your web development projects. Additionally, we report a number of empirical studies in which we apply our approach to a number of open-source and industrial Web applications and elaborate on the obtained results.Ījax, or Asynchronous JavaScript and XML, exploded onto the scene in the spring of 2005 and remains the hottest story among web developers. We present our open source tool called Crawljax, which implements the concepts and algorithms discussed in this article. In this article, we discuss our sequential and concurrent Ajax crawling algorithms. This inferred model can be used in program comprehension and in analysis and testing of dynamic Web states, for instance, or for generating a static version of the application. Our algorithm scans the DOM tree, spots candidate elements that are capable of changing the state, fires events on those candidate elements, and incrementally infers a state machine that models the various navigational paths and states within an Ajax application. This article describes a novel technique for crawling Ajax-based applications through automatic dynamic analysis of user-interface-state changes in Web browsers. At the same time, such techniques-collectively known as Ajax-shatter the concept of webpages with unique URLs, on which traditional Web crawlers are based. Using JavaScript and dynamic DOM manipulation on the client side of Web applications is becoming a widespread approach for achieving rich interactivity and responsiveness in modern Web applications. Finally, the checker performs verification: if there is a violation of specifications, NuSMV allows to locate errors in WA design and appropriate adjustments are carried out. The prototype system we have implemented embeds a component which automatically imports WA design from a UML tool CTL specifications are added and translated as source code for NuSMV model checker. Then, by using the CTL formal language, we formalize basic criteria to establish correctness of the application. Specifically, the mathematical model of the WA is represented by a Finite State Machine (FSM). The tool first performs the modeling of the WA and furthermore verify it by means of a model checker. In this paper we present WAVer, a prototype tool for performing the verification of a WA design by means of Symbolic Model Checking techniques. Hence methods to support design and automatically perform validation of a Web Application (WA) could be helpful. Web Applications are becoming more and more widespread and efficient, then an increase of their reliability is now strongly required. The input for the tool was created within 15 min of exploratory testing. In addition, our tool does not require manual configuration before crawling. Our approach can reduce the crawling time by hours, while compromising the coverage achieved by 0.2% to 7.43%. These applications were randomly tested with state-of-the-art tools. We performed a case study with 5 Web applications. They are also exploited for steering the crawling and test case generation process. They are replayed as pre-recorded test cases. These sequences can be captured during exploratory tests. We introduce a tool that takes a set of recorded event sequences as input. We propose a semi-automated approach instead. This is due to the lack of insight and domain knowledge of crawling tools regarding the application under test. Although these approaches are fully automated, they consume too much time and they usually require manual configuration. The crawling process results in a state transition model, which is used for generating test cases. These approaches mainly rely on tools that explore an application by crawling it. There are fully automated approaches proposed for Web application testing.
