Approximately 15% of the global population is affected by some sort of disability, according to the World Report on Disability. Many C-Suite executives perceive digital accessibility (DA) as an endless task. Among the engineering leaders, one in four leaders are reliant on very limited knowledge about digital accessibility. Many countries are increasing their legislative efforts to make web accessibility an important part in web development and testing of software releases. Numerous organizations are facing extreme turbulence when not adhering to international accessibility guidelines while developing their software's and website applications. Web Content Accessibility Guidelines (WCAG) is a global guide on accessibility recommendations that are developed through the World Wide Web Consortium (W3C) to help organizations to meet minimum standard accessibility guidelines. It has become critical for every organization to focus on implementing the accessibility checks at every stage of their application development to avoid costly mistakes. Meanwhile, the need for front-end engineers and Quality Assurance (QA) test analysts to learn WCAG best practices is immensely important for the growing need to incorporate accessibility-focused inclusive design, development, and extensive accessibility testing, which are essential for most of the customer-facing websites. In a fast-paced world, incorporating shift left accessibility within development and testing is the new normal. The Web Accessibility Project: Development and Testing Best Practices helps developers address right accessibility attributes to user interface (UI) components. It also helps developers focus on developing manual and automation tests for QA professionals to inject accessibility audit, accessibility functional tests, and accessibility automation tests as part of their Continuous Integration and Continuous Development (CI/CD) models. The book is filled with readily usable best practices to adapt web accessibility early in application development. By applying the accessibility best practices covered in this book, developers can help their organizations rise to a whole new level of accessibility adherence, innovation, and inclusive design. They will also see greater work satisfaction in their professional lives and a way to help improve digital accessibility for end users.

For courses in computer programming and engineering. Beginner to Intermediate Programming in Java This book is designed to serve as a textbook and reference for programming in the Java language. Although it does include programming techniques, it is organised around the features of the Java language rather than any particular curriculum of programming techniques. The main audience is undergraduate students who have not had extensive programming experience with the Java language. The introductory chapters are written at a level that is accessible to beginners, while the boxed sections of those chapters serve to quickly introduce more experienced programmers to basic Java syntax. Later chapters are still designed to be accessible, but are written at a level suitable for students who have progressed to these more advanced topics.

Description Vue.js is one of the fastest growing and most popular open-source JavaScript frameworks around. Vue's meteoric success is found in its simplicity and short learning curve, but few resources are available to teach you how to test a Vue application effectively and efficiently. Testing Vue.js Applications is a comprehensive guide to testing Vue components, methods, events, and output. Author Edd Yerburgh, creator of the Vue testing utility avoriaz, teaches readers how to set up effective testing practices. Key features * Creating and testing Vue mixins * Building and testing component output, method, and events * Running unit tests, snapshot tests, and end to end tests in Jest Audience Written for developers with an intermediate knowledge of JavaScript, HTML, and CSS and a basic understanding of Vue.js. Some experience with ES6 is helpful, but not required. About the technology Vue is a powerful web framework that changes the way you build web UI. To test applications built with Vue, you need to master a new set of tools and techniques designed to work with Vue's unique reactive design and the flexible collection of components that make up the Vue stack. Edd Yerburgh is an experienced JavaScript developer and Vue core contributor. He is the main author of the official Vue test library and a prominent figure in the Vue testing community.

This volume provides an overview and an understanding of REST (Representational State Transfer). Discussing the constraints of REST the book focuses on REST as a type of web architectural style. The focus is on applying REST beyond Web applications (i.e., in enterprise environments), and in reusing established and well-understood design patterns when doing so. The reader will be able to understand how RESTful systems can be designed and deployed, and what the results are in terms of benefits and challenges encountered in the process.

Since REST is relatively new as an approach for designing Web Services, the more advanced part of the book collects a number of challenges to some of the assumptions and constraints of REST, and looks at current research work on how REST can be extended and applied to scenarios that often are considered not to be a good match for REST.

This work will help readers to reach a deeper understanding of REST on a practical as well as on an advanced level.

Nowadays, Web applications are almost omnipresent. The Web has become a platform not only for information delivery, but also for eCommerce systems, social networks, mobile services, and distributed learning environments. Engineering Web applications involves many intrinsic challenges due to their distributed nature, content orientation, and the requirement to make them available to a wide spectrum of users who are unknown in advance. The authors discuss these challenges in the context of well-established engineering processes, covering the whole product lifecycle from requirements engineering through design and implementation to deployment and maintenance. They stress the importance of models in Web application development, and they compare well-known Web-specific development processes like WebML, WSDM and OOHDM to traditional software development approaches like the waterfall model and the spiral model. .
