Alter the curl timeout when using behat and goutte

behat.yml

#  Problem:
#
#    Behat tests fail with messages like:
#    [curl] 28: Operation timed out after 30096 milliseconds with 0 bytes received
#
#  Reason:
#
#    By default, goutte sets CURLOPT_TIMEOUT to 30 seconds
#
#  Solution:
#
#    You can alter CURLOPT_TIMEOUT universally in your behat tests 
#    by adding a "guzzle_parameters" subsection to your goutte
#    definition
#
#    In the example below I set the timeout to 60 seconds
#
default:
  paths:
    features: tests/features
    bootstrap: %behat.paths.features%/bootstrap
  extensions:
    Behat\MinkExtension\Extension:
      goutte:
        guzzle_parameters:
          curl.options:
            CURLOPT_TIMEOUT: 60
