Edit the behat.local.yml file and update the base_url to point to the local hostname you want to test, and set the drupal_root to the path to your Drupal installation. You will find behat in the bin/ directory. You can run the complete set of tests by running bin/behat You can test a specific feature by running bin/behat features/some_feature.feature Run bin/behat --help to see all the options. Running bin/behat -dl will give you a listing of all of the current step definitions. Refer to http://www.dspeak.com/drupalextension/ for more information on using Behat with Drupal.
