ruby-on-rails - 无法让 RSpec View 规范通过

Question

我在 spec/views/users/new.html.erb_spec.rb 中有以下规范:

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

但是当我运行测试时它失败了:

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

失败的线路是:

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

在 new 方法的 Users Controller 中，我有以下内容:

@user = User.new

有什么想法为什么我会收到这个错误吗？

更新:根据请求，这是我的路线文件...

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

View 规范与用户 Controller 完全隔离运行。因此，您必须自己初始化 View 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

如果您想与 Controller 一起测试 View ，我建议您考虑使用 Cucumber 进行集成测试。
