description: Automated testing is a cornerstone of agile development. 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 "
