This document discusses Behavior Driven Development (BDD) using Cucumber for Java. It explains that BDD combines test-driven development, domain-driven design, and use of a common language to specify functionality in a way that is readable to both technical and non-technical stakeholders. Cucumber allows writing specifications in a Given/When/Then format that can be parsed and executed as tests. It provides an example specification and Java code to implement it. Benefits of the BDD approach include improved communication, reduced rework, and better maintained regression tests.
