Capybara请求规范DSL和交易固定装置

Question

在capybara 1.0.0.rc1中有一个新的dsl，与牛排非常相似。我正在尝试在后台/部分之前设置一个夹具，但是当我调试第一个场景/示例并检查数据库时，在后台设置的夹具已经消失。我将use_transaction_fixtures设置为true，但奇怪的是，因为background是以前的别名，所以这很重要。我做错了什么？

spec_helper.rb

require 'rubygems'
require 'spork'
require 'capybara/rspec'

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 'rails generate rspec:install'
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require File.expand_path(File.dirname(__FILE__) + "/blueprints")

  # Requires supporting ruby files with custom matchers and macros, etc,
  # in spec/support/ and its subdirectories.
  Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

  RSpec.configure do |config|
    # == Mock Framework
    #
    # 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
    config.mock_with :rspec

    # If you're not using ActiveRecord, or you'd prefer not to run each of your
    # examples within a transaction, remove the following line or assign false
    # instead of true.
    config.use_transactional_fixtures = true

    config.before(:all)    { Sham.reset(:before_all)  }
    config.before(:each)   { Sham.reset(:before_each) }
  end 
end 

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

出于某种原因，在我的环境/ test.rb中将config.cache_classes设置为true使其按预期工作。不知道为什么。
