Behat Selenium Configuration

Behat is based on the principles of BDD (Behavior-Driven Development). Basically, it is used to test the behavior of the application from end user’s point of view.  Behat use Gherkin-language that is similar to English language and extended by custom PHP functions. These functions are written in FeatureContext.php file which is created inside the bootstrap folder.

Create file composer.json and behat.yml

composer.json : It consists of various dependencies that Behat requirement.
