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 include

- Writing 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.
