This document discusses the benefits of automated testing and provides an introduction to Behat, an automated testing framework for PHP. It notes that automated tests can catch bugs before they hit production, improve team morale, and allow for faster code iterations. The document then demonstrates how to install and run Behat tests on a Drupal site using Gherkin syntax and scenarios. Resources for learning more about Behat, Mink, and test-driven development are also provided.
