使用 Rspec 测试模型中的关系和方法 [英] Testing the relationships and Methods In Model using Rspec

问题描述

我正在从事 rails 项目，我是 rails 新手，我想使用 rspec 测试我的模型关系和模型中的方法.我怎么能这样做我的模型关系是这样的

I m working on rails project and i m new on rails and I want to test my model relationships and methods in model using rspec. How could I do this my model relationships are like this

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

My idea_spec.rb file is

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

推荐答案

如果你使用 shoulda-matchers (https://github.com/thoughtbot/shoulda-matchers) gem 你可以把这些写成 it{should归属于(:人)}

If you use shoulda-matchers (https://github.com/thoughtbot/shoulda-matchers) gem you can write these as it{should belong_to(:person)}

但老实说，我并没有从这些类型的测试中得到很多，AR 测试得很好.

But to be honest I don't get a lot out of these types of test, AR is well tested.
