This document discusses Behaviour-Driven Development (BDD) using the Ruby testing frameworks Cucumber and RSpec. It explains that BDD involves writing feature tests in Cucumber's Gherkin language first to specify desired behaviors before implementing the code and RSpec unit tests to validate those behaviors are met. The document also covers Guard and Spork for test automation and Jenkins for continuous integration.
