Behavior Driven Development Framework for PHP: Behat

Behat is an open source behavior driven development framework for PHP. Behat was inspired by Ruby’s Cucumber project and especially it’s syntax part Gherkin.

Unlike any other PHP testing framework that tests applications inside out. Behat is testing applications outside in. It means, that Behat works only with your application’s input/output.

There are Symfony plugin and Symfony2 bundle for Behat, so you can start testing your applications right now.
