We've all been there. You work incredibly hard to develop a feature and design tests based on written requirements. You build a detailed test plan that aligns the tests with the software and the documented business needs. When you put the tests to the software, it all falls apart because the requirements were updated without informing everyone. But help is at hand. Enter business-driven development and Cucumber, a tool for running automated acceptance tests. Join Mary Thorn as she explores the nuances of Cucumber and shows you how to implement specification-by-example, behavior-driven development, and agile acceptance testing. By fostering collaboration for implementing active requirements via a common language and format, Cucumber bridges the communication gap between business stakeholders and implementation teams.
