Acceptance Test Driven Development (ATDD) is a very effective development practice that essentially involves writing specifications in the form of documented and automated examples. These automated examples become automated acceptance tests that validate the features being delivered. The process of writing these examples encourages teams to focus on where the business value of a feature is coming from, which in turn helps developers aim for the most appropriate solutions in business terms.
When I help folks out with ATDD and TDD practices, one common question people ask me is this: Does using ATDD cost more in development time?
