我刚开始在测试时使用工厂女孩来更换夹具。我正在开发一个 twitter 客户端，我正在尝试使用 factory girl 创建用于测试的 twitter 对象。当我单独创建它们时，这很好。但是，如果我尝试将它们关联起来，我会收到以下错误。

Factory.define :status, :class => Twitter::Status, :default_strategy => :build do |t|
  t.text 'Test Twitter Status message'
  t.association :user, :factory => :twitter_user #this line causes the problems
end

Factory.define :twitter_user, :class => Twitter::User, :default_strategy => :stub do |u|
  u.profile_image_url "#{RAILS_ROOT}/public/images/rails.png"
end

导致问题的t.association :user, :factory => :twitter_user原因是当它存在时会引发此异常。有没有什么办法解决这一问题？还是工厂女孩只是为 activerecord 对象设计的？谢谢

我很确定工厂女孩只是用于 ActiveRecord 对象，如果您使用 rSpec 可能（如果我的语法正确），您应该能够模拟和存根 Twitter::User 对象而不是使用工厂：

@twitter_user = mock(Twitter::User, :profile_image =>"#{RAILS_ROOT}/public/images/rails.png")

然后将其附加到需要它的对象上。

这可能不太正确，但这是我要开始的道路。
