The document discusses Behavior Driven Development (BDD) using Cucumber, Selenium, and PhantomJS. Cucumber uses a natural language syntax called Gherkin to write automated acceptance tests. Selenium is used to automate interactions with a web browser, while PhantomJS allows running those tests headlessly on a CI server without requiring a graphical browser. The example project demonstrates how Cucumber features written by PMs/BAs can be linked to Selenium step definitions to test a web application.
