使用Rspec在模型中测试关系和方法

Question

我正在研究rails项目和我在rails上的新功能,我想使用rspec在模型中测试我的模型关系和方法.我怎么能这样做我的模型关系是这样的

class Idea < ActiveRecord::Base

  belongs_to :person
  belongs_to :company
  has_many :votes
  validates_presence_of :title, :description
  def published?
    if self.status == "published"
      return true
    else
      return false
    end
  end

  def image_present
    if self.image_url
      return self.image_url
    else
      return "/images/image_not_found.jpg"
    end
  end



  def voted
    self.votes.present?
  end
end

我的idea_spec.rb文件是

require 'spec_helper'

describe Idea do

  it "should have title" do
  Idea.new(:title=>'hello',:description=>'some_desc').should be_valid
  end

  it "should have description" do
  Idea.new(:title=>'hello',:description=>'some_desc').should be_valid
  end
end

如果您使用shoulda-matchers(https://github.com/thoughtbot/shoulda-matchers)gem,您可以将其写为 it{should belong_to(:person)}

但说实话,我没有从这些类型的测试中得到很多,AR经过了很好的测试.
