使用rspec测试Draper增强的模型

Question

我对我的视图进行了rspec测试，在我使用draper抽象出一些逻辑之前，它工作得很好。视图在浏览器中正确呈现，但测试现在失败。

require 'spec_helper'

describe "articles/index.html.erb" do
  before(:each) do
    assign(:articles, [
      stub_model(Article,
        :title => "Title",
        :slug => "this-is-a-slug",
        :content => "Content",
        :excerpt => "Excerpt",
        :starts_at => "2012-01-10 01:00:00",
        :ends_at => "2012-01-10 01:30:00",
        :show_times => true
      )
    ])
    render
  end

  it "renders a list of articles" do
    assert_select "h3", :text => "Title".to_s, :count => 8
    assert_select "div.article_body", :text => "Content".to_s, :count => 8
  end
end

该视图包含对装饰器方法calendars的调用，该方法在装饰器/文章_装饰器.rb中定义，但rspec没有采用此方法，可能是因为我使用的是stub_model：

1) articles/index.html.erb renders a list of articles
   Failure/Error: render
   ActionView::Template::Error
   undefined method `calendars' for #<Article:0x007fd41c68be90>
   # ./app/views/articles/index.html.erb:4:in `block in _app_views_articles_index_html_erb___1865228919968458103_70274492660680'
   # ./app/views/articles/index.html.erb:1:in `each'
   # ./app/views/articles/index.html.erb:1:in `_app_views_articles_index_html_erb___1865228919968458103_70274492660680'
   # ./spec/views/articles/index.html.erb_spec.rb:85:in `block (2 levels) in <top (required)>'

我怎样才能让我的测试再次工作？(或者有没有更好的方法来测试我的视图？)

Answer 1

我还没有开始使用Draper，但我想这应该是可行的：

assign(:articles, [
    ArticleDecorator.new(
      stub_model(Article,
        :title => "Title",
        :slug => "this-is-a-slug",
        :content => "Content",
        :excerpt => "Excerpt",
        :starts_at => "2012-01-10 01:00:00",
        :ends_at => "2012-01-10 01:30:00",
        :show_times => true
        )
      )])

现在文章是一个装饰器数组，它响应calendars方法。
