# By default if you have the FakeWeb gem installed when the specs are
# run they will hit recorded responses.  However, if you don't have
# the FakeWeb gem installed or you set the environment variable
# LIVE_TEST then the tests will hit the live site gares-en-mouvement.com.
#
# Having both methods available for testing allows you to quickly
# refactor and add features, while also being able to make sure that
# no changes to the gares-en-mouvement.com interface have affected the parser.
