An effective testing strategy will deliver new functionality more aggressively, accelerate user feedback, and improve quality. However, for many developers, creating effective automated tests is a unique and unfamiliar challenge. xUnit Test Patterns is the definitive guide to writing automated tests using xUnit, the most popular unit testing framework in use today. Agile coach and test automation expert Gerard Meszaros describes 68 proven patterns for making tests easier to write, understand, and maintain. He then shows you how to make them more robust and repeatable--and far more cost-effective. Loaded with information, this book feels like three books in one. The first part is a detailed tutorial on test automation that covers everything from test strategy to in-depth test coding. The second part, a catalog of 18 frequently encountered "test smells," provides trouble-shooting guidelines to help you determine the root cause of problems and the most applicable patterns. The third part contains detailed descriptions of each pattern, including refactoring instructions illustrated by extensive code samples in multiple programming languages. Topics covered includeWriting better tests--and writing them faster The four phases of automated tests: fixture setup, exercising the system under test, result verification, and fixture teardown Improving test coverage by isolating software from its environment using Test Stubs and Mock Objects Designing software for greater testability Using test "smells" (including code smells, behavior smells, and project smells) to spot problems and know when and how to eliminate them Refactoring tests for greater simplicity, robustness, and execution speed This book will benefit developers, managers, and testers working with any agile or conventional development process, whether doing test-driven development or writing the tests last. While the patterns and smells are especially applicable to all members of the xUnit family, they also apply to next-generation behavior-driven development frameworks such as RSpec and JBehave and to other kinds of test automation tools, including recorded test tools and data-driven test tools such as Fit and FitNesse.Visual Summary of the Pattern Language Foreword Preface Acknowledgments Introduction Refactoring a Test PART I: The Narratives Chapter 1 A Brief Tour Chapter 2 Test Smells Chapter 3 Goals of Test Automation Chapter 4 Philosophy of Test Automation Chapter 5 Principles of Test Automation Chapter 6 Test Automation Strategy Chapter 7 xUnit Basics Chapter 8 Transient Fixture Management Chapter 9 Persistent Fixture Management Chapter 10 Result Verification Chapter 11 Using Test Doubles Chapter 12 Organizing Our Tests Chapter 13 Testing with Databases Chapter 14 A Roadmap to Effective Test Automation PART II: The Test Smells Chapter 15 Code Smells Chapter 16 Behavior Smells Chapter 17 Project Smells PART III: The Patterns Chapter 18 Test Strategy Patterns Chapter 19 xUnit Basics Patterns Chapter 20 Fixture Setup Patterns Chapter 21 Result Verification Patterns Chapter 22 Fixture Teardown Patterns Chapter 23 Test Double Patterns Chapter 24 Test Organization Patterns Chapter 25 Database Patterns Chapter 26 Design-for-Testability Patterns Chapter 27 Value Patterns PART IV: Appendixes Appendix A Test Refactorings Appendix B xUnit Terminology Appendix C xUnit Family Members Appendix D Tools Appendix E Goals and Principles Appendix F Smells, Aliases, and Causes Appendix G Patterns, Aliases, and Variations Glossary References Index "

    They had packed up their family in Vancouver, BC, and moved to Delft to experience the biking city as residents rather than as visitors. A year earlier they had become unofficial ambassadors for Dutch cities with the publication of their first book Building the Cycling City: The Dutch Blueprint for Urban Vitality.   In Curbing Traffic: The Human Case for Fewer Cars in Our Lives, Melissa and Chris Bruntlett chronicle their experience living in the Netherlands and the benefits that result from treating cars as visitors rather than owners of the road. They weave their personal story with research and interviews with experts and Delft locals to help readers share the experience of living in a city designed for people.   In the planning field, little attention is given to the effects that a “low-car” city can have on the human experience at a psychological and sociological level. Studies are beginning to surface that indicate the impact that external factors—such as sound—can have on our stress and anxiety levels. Or how the systematic dismantling of freedom and autonomy for children and the elderly to travel through their cities is causing isolation and dependency.   In Curbing Traffic, the Bruntletts explain why these investments in improving the built environment are about more than just getting from place to place more easily and comfortably. The insights will help decision makers and advocates to better understand and communicate the human impacts of low-car cities: lower anxiety and stress, increased independence, social autonomy, inclusion, and improved mental and physical wellbeing.   The book is organized around the benefits that result from thoughtfully curbing traffic, resulting in a city that is: child-friendly, connected, trusting, feminist, quiet, therapeutic, accessible, prosperous, resilient, and age-friendly.   Planners, public officials, and citizen activists should have a greater understanding of the consequences that building for cars has had on communities (of all sizes). Curbing Traffic provides relatable, emotional, and personal reasons why it matters and inspiration for exporting the low-car city.
