Master BDD to deliver higher-value software more quickly

To develop high-value products quickly, software development teams need better ways to collaborate. Agile methods like Scrum and Kanban are helpful, but they're not enough. Teams need better ways to work inside each sprint or work item. Behavior-driven development (BDD) adds just enough structure for product experts, testers, and developers to collaborate more effectively.

Drawing on extensive experience helping teams adopt BDD, Richard Lawrence and Paul Rayner show how to explore changes in system behavior with examples through conversations, how to capture your examples in expressive language, and how to flow the results into effective automated testing with Cucumber. Where most BDD resources focus on test automation, this guide goes deep into how BDD changes team collaboration and what that collaboration looks like day to day. Concrete examples and practical advice will prepare you to succeed with BDD, whatever your context or role.

- Learn how to collaborate better by using concrete examples of system behavior

- Identify your project's meaningful increment of value so you're always working on something important

- Begin experimenting with BDD slowly and at low risk

- Move smoothly from informal examples to automated tests in Cucumber

- Use BDD to deliver more frequently with greater visibility

- Make Cucumber scenarios more expressive to ensure you're building the right thing

- Grow a Cucumber suite that acts as high-value living documentation

- Sustainably work with complex scenario data

- Get beyond the "mini-waterfalls" that often arise on Scrum teams

Four-time winner of the best Computer Science and Engineering textbook of the year award from the Textbook and Academic Authors Association, Computer Organization and Architecture: Designing for Performance provides a thorough discussion of the fundamentals of computer organization and architecture, covering not just processor design, but memory, I/O, and parallel systems. Coverage is supported by a wealth of concrete examples emphasizing modern RISC, CISC, and superscalar systems. Undergraduates and professionals in computer science, computer engineering, and electrical engineering courses will learn the fundamentals of processor and computer design from this award-winning text.

Virtually every computing system today is part of a distributed system. Programmers, developers, and engineers need to understand the underlying principles and paradigms as well as the real-world application of those principles. Now, internationally renowned expert Andrew S. Tanenbaum – with colleague Martin van Steen – presents a complete introduction that identifies the seven key principles of distributed systems, with extensive examples of each. Adds a completely new chapter on architecture to address the principle of organizing distributed systems. Provides extensive new material on peer-to-peer systems, grid computing and Web services, virtualization, and application-level multicasting. Updates material on clock synchronization, data-centric consistency, object-based distributed systems, and file systems and Web systems coordination. For all developers, software engineers, and architects who need an in-depth understanding of distributed systems.

The classic text, Interaction Design by Sharp, Preece and Rogers is back in a fantastic new 2^nd Edition!

New to this edition:

• Completely updated to include new chapters on Interfaces, Data Gathering and Data Analysis and Interpretation, the latest information from recent research findings and new examples
• Now in full colour
• A lively and highly interactive Web site that will enable students to collaborate on experiments, compete in design competitions, collaborate on designs, find resources and communicate with others
• A new practical and process-oriented approach showing not just what principals ought to apply, but crucially how they can be applied

"The best basis around for user-centered interaction design, both as a primer for students as an introduction to the field, and as a resource for research practitioners to fall back on. It should be labelled 'start here'."
—Pieter Jan Stappers, ID-StudioLab, Delft University of Technology

Embracing in full the new features of the Java 2 platform as they apply to CS1 topics, this leading textbook continues to teach beginning programmers how to design and implement high-quality object-oriented software. New to the second edition is a chapter entitled "Input and Output" (Ch. 7), which explains the class library used earlier in the text and explores other I/O issues such as streams, file I/O, and network-based I/O. Applets and applications are intertwined throughout the book to demonstrate computing concepts-applets, introduced in Ch. 2, build on the excitement of the web, while applications allow students to gain a clear understanding of programming concepts. Lewis and Loftus have expanded their coverage of classes and objects with this edition (introduced in Ch. 4) to provide more in-depth discussion of methods and parameter passing, method and static variables, and method overloading. Discussion of Swing architecture and components is also new to this edition, as well as the inclusion of new Collection classes. The Update to the second edition has been published to provide readers with additional resources to enhance their learning.It includes a CD-ROM with various development environments, the textbook example code, and the presentation slides from the book. The typeface for of some of the code has been redesigned to make it more legible. Lastly, the update includes all corrections that have been discovered since the second edition's publication. The main content and flow of the update will remain as it is.

This Fifth Edition is completely revised and expanded to cover JavaScript as it is used in today's Web 2.0 applications. This book is both an example-driven programmer's guide and a keep-on-your-desk reference, with new chapters that explain everything you need to know to get the most out of JavaScript, including:

Scripted HTTP and AjaxXML processingClient-side graphics using the canvas tagNamespaces in JavaScript--essential when writing complex programsClasses, closures, persistence, Flash, and JavaScript embedded in Java applications

Part I explains the core JavaScript language in detail. If you are new to JavaScript, it will teach you the language. If you are already a JavaScript programmer, Part I will sharpen your skills and deepen your understanding of the language.

Part II explains the scripting environment provided by web browsers, with a focus on DOM scripting with unobtrusive JavaScript. The broad and deep coverage of client-side JavaScript is illustrated with many sophisticated examples that demonstrate how to: Generate a table of contents for an HTML documentDisplay DHTML animationsAutomate form validationDraw dynamic pie chartsMake HTML elements draggableDefine keyboard shortcuts for web applicationsCreate Ajax-enabled tool tipsUse XPath and XSLT on XML documents loaded with AjaxAnd much more

Part III is a complete reference for core JavaScript. It documents every class, object, constructor, method, function, property, and constant defined by JavaScript 1.5 and ECMAScript Version 3.

Part IV is a reference for client-side JavaScript, covering legacy web browser APIs, the standard Level 2 DOM API, and emerging standards such as the XMLHttpRequest object and the canvas tag.

More than 300,000 JavaScript programmers around the world have madethis their indispensable reference book for building JavaScript applications.

""A must-have reference for expert JavaScript programmers...well-organized and detailed.""-- Brendan Eich, creator of JavaScript

A source of information for network administrators, engineers and instructors who want to obtain Novell certification or, having already acquired it, use it to their best advantage. The book includes a study guide with sample questions that help prepare test takers for the exams.
