However, for many developers, creating effective automated tests is a unique and foreign challenges. XUnit Test Patterns is the definitive guide to writing automated tests using xUnit, the most popular unit testing framework in use today. The first part is a detailed tutorial on test automation that covers everything from test strategy to examine in depth coding. The third section contains detailed descriptions of each pattern, including refactoring instructions illustrated by extensive code samples in multiple programming languages. Topics covered include Write better tests - and writing them faster Fourth automated test phase: fixture setup, implement a system that was tested, the results of verification, and fixture teardown Improving test coverage by isolating software from the 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, reliability, and speed of execution This book will benefit developers, managers, and testers working with agile or conventional development process, whether doing test-driven development or writing the last test. While the pattern and the smell is particularly true for all members of the xUnit family, they also apply to generation development framework-driven behavior such as RSpec and JBehave and for other types of test automation tools, including recorded test tools and data-driven test tools such as Fit and FitNesse.
