/spec/spec_helper.rbを編集

require 'rubygems'
require 'spork'

Spork.prefork do
  # Loading more in this block will cause your tests to run faster. However, 
  # if you change any configuration or code from libraries loaded here, you'll
  # need to restart spork for it take effect.

  # This file is copied to ~/spec when you run 'ruby script/generate rspec'
  # from the project root directory.
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path(File.join(File.dirname(__FILE__),'..','config','environment'))
  require 'spec/autorun'
  require 'spec/rails'

  # Uncomment the next line to use webrat's matchers
  #require 'webrat/integrations/rspec-rails'

  # Requires supporting files with custom matchers and macros, etc,
  # in ./support/ and its subdirectories.
  Dir[File.expand_path(File.join(File.dirname(__FILE__),'support','**','*.rb'))].each {|f| require f}

  Spec::Runner.configure do |config|
    # If you're not using ActiveRecord you should remove these
    # lines, delete config/database.yml and disable :active_record
    # in your config/boot.rb
    config.use_transactional_fixtures = true
    config.use_instantiated_fixtures  = false
    config.fixture_path = RAILS_ROOT + '/spec/fixtures/'

    # == Fixtures
    #
    # You can declare fixtures for each example_group like this:
    #   describe "...." do
    #     fixtures :table_a, :table_b
    #
    # Alternatively, if you prefer to declare them only once, you can
    # do so right here. Just uncomment the next line and replace the fixture
    # names with your fixtures.
    #
    # config.global_fixtures = :table_a, :table_b
    #
    # If you declare global fixtures, be aware that they will be declared
    # for all of your examples, even those that don't use them.
    #
    # 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 it's 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
  end

end

Spork.each_run do
  # This code will be run each time you run your specs.

end

# --- Instructions ---
# - Sort through your spec_helper file. Place as much environment loading 
#   code that you don't normally modify during development in the 
#   Spork.prefork block.
# - Place the rest under Spork.each_run block
# - Any code that is left outside of the blocks will be ran during preforking
#   and during each_run!
# - These instructions should self-destruct in 10 seconds.  If they don't,
#   feel free to delete them.

  # if you change any configuration or code from libraries loaded here, you'll

  # IMPORTANT: This file was generated by Cucumber 0.4.3
  # Edit at your own peril - it's recommended to regenerate this file
  # in the future when you upgrade to a newer version of Cucumber.

  # You can still turn off transactions on a per-scenario basis, simply tagging 
  # a feature or scenario with the @no-txn tag. 
  #
  # If you set this to false, transactions will be off for all scenarios,
  # regardless of whether you use @no-txn or not.
  #
  # Beware that turning transactions off will leave data in your database 
  # after each scenario, which can lead to hard-to-debug failures in 
  # subsequent scenarios. If you do this, we recommend you create a Before
  # block that will explicitly put your database in a known state.
  Cucumber::Rails::World.use_transactional_fixtures = true

  # If you set this to false, any error raised from within your app will bubble 
  # up to your step definition and out to cucumber unless you catch it somewhere
  # on the way. You can make Rails rescue errors and render error pages on a
  # per-scenario basis by tagging a scenario or feature with the @allow-rescue tag.
  #
  # If you set this to true, Rails will rescue all errors and render error
  # pages, more or less in the same way your application would behave in the
  # default production environment. It's not recommended to do this for all
  # of your scenarios, as this makes it hard to discover errors in your application.
