What is Behat?

● Welcome to Behat! Behat is a tool that makes behavior

driven development(BDD) possible. With BDD, you write

human-readable stories that describe the behavior of your

application. These stories can then be auto-tested against

your application. And yes, it’s as cool as it sounds!

Drupal Extension

performance of these common Drupal testing tasks:

● Set up test data with Drush or the Drupal API

● Define theme regions and test data appears within them

● Clear the cache, log out, and other useful steps

● Detect and discover steps provided by contributed

modules and themes
