Summary

With agile Acceptance Test Driven Development (ATDD), business customers, testers, and developers can collaborate to produce testable requirements that lead directly to better software. However, agile ATDD is still widely misunderstood. Now, there's a practical, entry-level, hands-on guide to implementing and successfully applying it. ATDD By Examplewalks readers step-by-step through deriving the right systems from business users, and then implementing fully automated functional tests that accurately reflect business requirements, are comprehensible to business stakeholders, and actually help development teams build high-quality software more rapidly. Leading practitioner Markus Gärtner describes how ATDD is applied through two example projects using two common frameworks in two different languages. Through these realistic examples, he illuminates ATDD's fundamental principles, helping both test and business professionals understand how it fits with their roles and goals, and offering concrete advice on what works and what doesn't. More than any other book on the subject, ATDD By Examplefocuses on the nitty-gritty details software professionals need to master. In particular, it contains excellent coverage of the crucial topic of collaborative specification discussions, and indispensable guidance on choosing and utilizing software test automation suites for use with ATDD.
