5. Agenda
● Introduction to Behat
● Behat Drupal Extension
● Behat Installation/Configuration
● Behat test execution from command line
● A real world example
● How to minimize regressing testing using Behat

6. 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!

7. Drupal Extension
The Drupal Extension to Behat and Mink assists in the
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
● Detail - https://www.drupal.org/project/drupalextension

8. Installation using Composer
1. Install Composer
2. Install the Drupal Extension in /opt/drupalextension
3. Create an alias to the behat binary in /usr/local/bin
