The document discusses the history and concepts of test-driven development (TDD) and behavior-driven development (BDD). It traces the origins of TDD from the 1970s and mentions how BDD grew out of TDD in the 2000s. It provides examples of test code written using the RSpec framework in Ruby to specify and test behaviors using a domain-specific language for writing tests.
