无法获得RSpec的视图规范通过

Question

我有以下规格的spec/views/users/new.html.erb_spec.rb：

require 'spec_helper' 

describe "users/new.html.erb" do 
    it "displays the text attribute of the message" do 
    render 
    response.should contain("Register") 
    end 
end 

但是当我运行测试失败：

ActionView::TemplateError in 'users/new.html.erb displays the text attribute of the message' 
Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id 

线是失败的是：

<% form_for @user, :url => account_path do |f| %> 

在我Users控制器为new方法，我有这样的：

@user = User.new 

任何想法，为什么我得到那个错误？

更新：根据要求，这里是我的路线文件...

ActionController::Routing::Routes.draw do |map| 
    map.resource :account, :controller => "users" 
    map.resources :users 

    map.connect ':controller/:action/:id' 
    map.connect ':controller/:action/:id.:format' 
end 

Answer 1

视图的定义是从用户控制器完全隔离运行。因此，您必须自己初始化视图中所需的变量，如here所述。结果会是这样的：

require 'spec_helper' 
require 'path/to/user.rb' 

describe "users/new.html.erb" do 
    it "displays the text attribute of the message" do 
    assigns[:user] = User.new 
    render 
    response.should contain("Register") 
    end 
end 

如果你想与你的控制器一起测试你的视图，我会建议寻找与黄瓜的集成测试。

Answer 2

只是一个更新的答案。

require 'spec_helper' 

describe "users/new.html.erb" do 
    it "displays the text attribute of the message" do 
    assign(:user, stub_model(User)) 
    render 
    expect(rendered).to include("Register") 
    end 
end 

这应该在轨道上运行3.2.13和RSpec 2.13.0
