The document discusses Behavior Driven Development (BDD) and testing in PHP. It introduces BDD and some common problems in testing like how to test dependencies. It then discusses tools for PHP testing like PHPUnit and PHP Spec 2. PHP Spec 2 is presented as a BDD framework for PHP that makes testing easy with matchers, test doubles and a TDD cycle approach. Examples are provided of how to write tests in PHP Spec 2.
