Test-Driven Development (TDD) is now an established technique for delivering better software faster. TDD is based on a simple idea: Write tests for your code before you write the code itself. However, this "simple" idea takes skill and judgment to do well. Now there's a practical guide to TDD that takes you beyond the basic concepts. Drawing on a decade of experience building real-world systems, two TDD pioneers show how to let tests guide your development and “grow” software that is coherent, reliable, and maintainable. Steve Freeman and Nat Pryce describe the processes they use, the design principles they strive to achieve, and some of the tools that help them get the job done. Through an extended worked example, you’ll learn how TDD works at multiple levels, using tests to drive the features and the object-oriented structure of the code, and using Mock Objects to discover and then describe relationships between objects. Along the way, the book systematically addresses challenges that development teams encounter with TDD—from integrating TDD into your processes to testing your most difficult features. Coverage includes Implementing TDD effectively: getting started, and maintaining your momentum throughout the project Creating cleaner, more expressive, more sustainable code Using tests to stay relentlessly focused on sustaining quality Understanding how TDD, Mock Objects, and Object-Oriented Design come together in the context of a real software development project Using Mock Objects to guide object-oriented designs Succeeding where TDD is difficult: managing complex test data, and testing persistence and concurrency
Today, information-technology business analysts are often working on object-oriented (OO), Unified Modeling Language (UML) projects, yet they have a long way to go to exploit the technology beyond the adoption of use cases (just one part of the UML). This

"Essential System Requirements targets the discovery and definition of critical system requirements in the analysis phase of system development - where good design is vital to the success of a project. This book explores a design methodology that involves users early on to describe essential business events. These events then partition the system response into logical, more easily managed segments. The result is a conceptual model that reflects real business needs and accelerates the entire delivery process."--BOOK JACKET.

The Complete Guide to Writing More Maintainable, Manageable, Pleasing, and Powerful Ruby Applications Ruby's widely admired ease of use has a downside: Too many Ruby and Rails applications have been created without concern for their long-term maintenance or evolution. The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site,poodr.info.

A Practical Guide to Acceptance Test-Driven Development
Author: Markus Gärtner
With Acceptance Test-Driven Development (ATDD), business customers, testers, and developers can collaborate to produce testable requirements that help them build higher quality software more rapidly. However, ATDD is still widely misunderstood by many practitioners. ATDD by Example is the first practical, entry-level, hands-on guide to implementing and successfully applying it. ATDD pioneer Markus Gärtner walks readers step by step through deriving the right systems from business users, and then implementing fully automated, functional tests that accurately reflect business requirements, are intelligible to stakeholders, and promote more effective development. Through two end-to-end case studies, Gärtner demonstrates how ATDD can be applied using diverse frameworks and languages. Each case study is accompanied by an extensive set of artifacts, including test automation classes, step definitions, and full sample implementations. These realistic examples illuminate ATDD’s fundamental principles, show how ATDD fits into the broader development process, highlight tips from Gärtner’s extensive experience, and identify crucial pitfalls to avoid. Readers will learn to Master the thought processes associated with successful ATDD implementation Use ATDD with Cucumber to describe software in ways businesspeople can understand Test web pages using ATDD tools Bring ATDD to Java with the FitNesse wiki-based acceptance test framework Use examples more effectively in Behavior-Driven Development (BDD) Specify software collaboratively through innovative workshops Implement more user-friendly and collaborative test automation Test more cleanly, listen to test results, and refactor tests for greater value If you’re a tester, analyst, developer, or project manager, this book offers a concrete foundation for achieving real benefits with ATDD now–and it will help you reap even more value as you gain experience.

A Practical Guide to the Models and Methods of Usage-Centered Design
Author: Larry L. Constantine,Lucy A.D. Lockwood
Publisher: Pearson Education
In the quest for quality, software developers have long focused on improving the internal architecture of their products. Larry L. Constantine--who originally created structured design to effect such improvement--now joins with well-known consultant Lucy A. D. Lockwood to turn the focus of software development to the external architecture. In this book, they present the models and methods of a revolutionary approach to software that will help programmers deliver more usable software--software that will enable users to accomplish their tasks with greater ease and efficiency. Recognizing usability as the key to successful software, Constantine and Lockwood provide concrete tools and techniques that programmers can employ to meet that end. Much more than just another set of rules for good user-interface design, this book guides readers through a systematic software development process. This process, called usage-centered design, weaves together two major threads in software development methods: use cases (also used with UML) and essential modeling. With numerous examples and case studies of both conventional and specialized software applications, the authors illustrate what has been shown in practice to work and what has proved to be of greatest practical value. Highlights Presents a streamlined process for developing highly usable software Describes practical methods and models successfully implemented in industry Complements modern development practices, including the Unified Process and other object-oriented software engineering approaches
This practical book by two industry leaders continues to be a self-teaching guide for software analysts and developers. This revised edition teaches readers how to actually "do" object-oriented modeling using UML notation as well as how to implement the model using C++. The authors introduce all of the basic object-oriented fundamentals necessary so readers can understand and apply the object-oriented paradigm. FEATURES Teaches readers to build an object-oriented application using C++ and make the right trade-off decisions to meet business needs. Exposes a number of the myths surround object-oriented technology while focusing on its practicality as a software engineering tool. Gives readers a "recipe or step-by-step guide to do all of the steps of object-oriented technology. Provides a practical approach to analysis, design, and programming in the object-oriented technology. NEW TO THE SECOND EDITION Gives a practical approach for the development of use cases as part of object-oriented analysis. Provides greater coverage of UML diagramming. Introduces key C++ libraries that provide important functionality, supporting implementation of an object-oriented model in C++. Improved coverage of dynamic behavior modeling, implementation of the state model, and class projects.
" Applying Use Case Driven Object Modeling with UML: An Annotated e-Commerce Example " is a practical, hands-on guide to putting use case methods to work in real-world situations. This workbook is a companion to "Use Case Driven Object Modeling with UML." It bridges the gap between the theory presented in the main book and the practical issues involved in the development of an Internet e-commerce application. Uniquely conceived as a workbook and featuring as a running example an e-commerce system for an online bookstore, "Applying Use Case Driven Object Modeling with UML" examines design in detail, demonstrating the most common design mistakes and the correct design solutions. The hands-on exercises allow you to detect, identify, and correct critical errors on your own, before reviewing the solutions provided in the book. Structured around the proven ICONIX Process, this workbook presents a streamlined approach to UML modeling designed to avoid analysis paralysis without skipping analysis and design. The book presents the four key phases of this minimalist approach to use case driven design--domain modeling, use case modeling, robustness analysis, and sequence diagramming--and for each topic provides an overview, detailed discussion, list of common mistakes, and a set of exercises for honing object modeling and design skills. The three chapters on reviews are also unique. The authors devote a chapter each to requirements review, preliminary design review, and critical design review. This focus on "designing quality in" by teaching how to review UML models fills a major gap in the published literature. Through examples, " Applying Use Case Driven Object Modeling with UML " shows you how to avoid more than seventy specific design errors, as illustrated by the "Top 10" error lists included as a handy key on the inside covers and within each chapter. With the information, examples, and exercises found here, you will develop the knowledge and skills you need to apply use case modeling more effectively to your next application. 0201730391B08022001
