+ # If you declare global fixtures, be aware that they will be declared

+ #
+ # You can also declare which fixtures to use (for example fixtures for test/fixtures):
+ #
+ # config.fixture_path = RAILS_ROOT + '/spec/fixtures/'
+ #
+ # == Mock Framework
+ #
+ # RSpec uses its own mocking framework by default. If you prefer to
+ # use mocha, flexmock or RR, uncomment the appropriate line:
+ #
+ # config.mock_with :mocha
+ # config.mock_with :flexmock
+ # config.mock_with :rr
+ #
+ # == Notes
+ #
+ # For more information take a look at Spec::Runner::Configuration and Spec::Runner
