XUnit Test Patterns uses the practice of patterns to share proven techniques for writing automated tests using the XUnit family (e.g., JUnit and NUnit) of test automation frameworks. When properly applied, these patterns result in tests that are easier to write, easier to understand, more robust and repeatable, easier to maintain, and ultimately more cost-effective. * Maximize software return on investment by learning how to refactor test code and reduce or prevent crippling test maintenance. * All patterns are introduced with a narrative section discussing the principles behind each one. * Includes a comprehensive glossary of testing and test automation terms.Software testing has received renewed attention with the widespread adoption of Extreme Programming and other agile methodologies. The under-appreciated practice of testing provides a timely and accurate measurement - a reality check - so that developers know whether any new action needs to be taken. And automated software testing ensures that once the software works, it is not accidentally broken during subsequent software development or maintenance activities.
