更新：我的spec_helper.rb

require 'rubygems'
require 'spork'

ENV["RAILS_ENV"] = "test"

Spork.prefork do
  require File.expand_path(File.dirname(__FILE__) + '/../config/environment')
  require 'rspec/rails'
end

Spork.each_run do
  # Hub::Application.reload_routes!
end

Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].each {|f| require f}

如果我移动需要File.expand_path(File.dirname(__ FILE__)’/../config/environment’)的prefork,我的模型不预加载,但是您可能期望运行我的测试需要更长的时间.

任何关于如何获得spork的Rails 3应用程序没有加载模型的想法？我试过使用spork 0.8.4,master分支,目前是0.9.0.rc3.有没有人有任何想法如何避免模型预加载？

解决方法

经过很多时间旋转我的车轮,我终于有了可以接受的东西：

Spork.prefork do
  require "rails/mongoid"
  Spork.trap_class_method(Rails::Mongoid,:load_models)

  # The following does not work correctly with Devise's routes that load the User model. 
  # Results in NameError unintitialized *
  # :reload_routes! triggers :devise_for which loads and caches the User class.
  # https://github.com/timcharper/spork/wiki/Spork.trap_method-Jujutsu
  # require "rails/application"
  # Spork.trap_method(Rails::Application,:reload_routes!) 

  require 'factory_girl_rails'
  Spork.trap_class_method(Factory,:find_definitions)

  require File.expand_path(File.dirname(__FILE__) + '/../config/environment')

end

问题主要是由于Rails :: Mongoid#load_models.在检查spork的调试输出和如何加载事情的回溯之后,提供了关于加载模型的一些线索.这个页面有更详细的https://github.com/timcharper/spork/wiki/Spork.trap_method-Jujutsu,但是我没有找到：reload_routes！帮助Devise强制将用户类预先加载.

我的规格现在运行得更快如果只有我可以让我的用户模式不被缓存,我才会幸福,但直到那时,我将会很满意.
