Behat Documentation

Behat is an open source behavior-driven development framework for PHP 5.3 and 5.4. What is behavior-driven development, you ask? It’s the idea that you start by writing human-readable sentences that describe a feature of your application and how it should work, and only then implement this behavior in software.

For example, imagine you’re about to create the famous UNIX ls command. Before you begin, you describe how the feature should work:

Feature: ls
  In order to see the directory structure
  As a UNIX user
  I need to be able to list the current directory's contents

  Scenario:
    Given I am in a directory "test"
    And I have a file named "foo"
    And I have a file named "bar"
    When I run "ls"
    Then I should get:
      """
      bar
      foo
      """

As a developer, your work is done as soon as you’ve made the ls command behave as described in the Scenario.

Now, wouldn’t it be cool if something could read this sentence and use it to actually run a test against the ls command? Hey, that’s exactly what Behat does! As you’ll see, Behat is easy to learn, quick to use, and will put the fun back into your testing.

Note

Behat was inspired by Ruby’s Cucumber project, especially its syntax (called Gherkin).
