Feature: Config reference
  In order to know the available configuration
  As a Behat user
  I need to be able to dump the configuration reference

  Scenario: Reference of defaults extension
    When I run "behat --no-colors --config-reference -v"
    Then it should pass
    And the output should contain:
      """
      suites:
      """
    And the output should contain:
      """
      exceptions:
      """

  Scenario: Custom extension
    Given a file named "behat.yml" with:
      """
      default:
        extensions:
          custom_extension.php: ~
      """
    And a file named "custom_extension.php" with:
      """
      <?php

      use Symfony\Component\Config\Definition\Builder\ArrayNodeDefinition;
      use Symfony\Component\DependencyInjection\ContainerBuilder;

      class CustomExtension implements Behat\Testwork\ServiceContainer\Extension {
          public function getConfigKey()
          {
              return 'custom_extension';
