How To Use It

1. Write your user stories ( Features and Scenarios ) in a human-readable format ( Gerkin language ).

   Feature: Some terse yet descriptive text of what is desired
   In order to realize a named business value
   As an explicit system actor
   I want to gain some beneficial outcome which furthers the goal
   
   Scenario: Some determinable business situation
   Given some precondition
   And some other precondition
   When some action by the actor
   And some other action
   And yet another action
   Then some testable outcome is achieved
   And something else we can check happens too
   

2. Back up your stories with code (Step Definitions).

   <?php
     /**
      * @Then /^some testable outcome is achieved$/
      */
     public function assertSomeTestableOutcomeIsAchieved() {
       // make your assertion here,
       // if it fails throw an exception
     }
