Growing Object-Oriented Software, Guided by Tests- P1

Growing Object-Oriented Software, Guided by Tests- P1: Test-Driven Development (TDD) hiện nay là một kỹ thuật được thành lập để cung cấp các phần mềm tốt hơn nhanh hơn. TDD là dựa trên một ý tưởng đơn giản: các bài kiểm tra Viết cho code của bạn trước khi bạn viết đoạn code riêng của mình. Tuy nhiên, điều này "đơn giản" ý tưởng có kỹ năng và bản án để làm tốt. Bây giờ có một tài liệu hướng dẫn thiết thực để TDD mà sẽ đưa bạn vượt ra ngoài những khái niệm cơ bản. Vẽ trên một...

Growing Object-Oriented Software, Guided by Tests- P1 Please purchase PDF Split-Merge on www.very Praise for Growing Object-Oriented Software, Guided by Tests “The authors of this book have led a revolution in the craft of programming by controlling the environment in which software grows. Their Petri dish is the mock object, and their microscope is the unit test. This book can show you how these tools introduce a repeatability to your work that would be the envy of any scientist.” —Ward Cunningham “At last a book, suffused with code, that exposes the deep symbiosis between TDD and OOD. The authors, pioneers in test-driven development, have packed it with principles, practices, heuristics, and (best of all) anecdotes drawn from their decades of professional experience. Every software craftsman will want to pore over the chapters of worked examples and study the advanced testing and design principles. This one’s a keeper.” —Robert C. Martin “Design is often discussed in depth, but without empiricism. Testing is often promoted, but within the narrow definition of quality that relates only to the presence or absence of defects. Both of these perspectives are valuable, but each on its own offers little more than the sound of one hand clapping. Steve and Nat bring the two hands together in what deserves—and can best be described as—applause. With clarity, reason, and humour, their tour de force reveals a view of design, testing, code, objects, practice, and process that is compelling, practical, and overflowing with insight.” —Kevlin Henney, co-author of Pattern-Oriented Software Architecture and 97 Things Every Programmer Should Know “Steve and Nat have written a wonderful book that shares their software craftsmanship with the rest of the world. This is a book that should be studied rather than read, and those who invest sufficient time and energy into this effort will be rewarded with superior development skills.” —David Vydra, publisher, testdriven.com “This book presents a unique vision of test-driven development. It describes the mature form of an alternative strain of TDD that sprang up in London in the early 2000s, characterized by a totally end-to-end approach and a deep emphasis on the messaging aspect of objects. If you want to be an expert in the state of the art in TDD, you need to understand the ideas in this book.” —Michael Feathers “With this book you’ll learn the rhythms, nuances in thinking, and effective programming practices for growing tested, well-designed object-oriented applications from the masters.” —Rebecca Wirfs-Brock This page intentionally left blank Growing Object-Oriented Software, Guided by Tests The Addison-Wesley Signature Series Kent Beck, Mike Cohn, and Martin Fowler, Consulting Editors Visit informit.com /awss for a complete list of available products. he Addison-Wesley Signature Series provides readers with T practical and authoritative information on the latest trends in modern technology for computer professionals.
