如何强制 rspec 中的视图失败？

我的 Rails 3 应用程序中有一个明显的错误。我正在将字段名称从“addr1”更改为“地址”（在我的“代理”模型中）。因此，当我尝试拉出编辑页面时，很自然地会出现以下错误。

  undefined method `addr1' for #<Agency:0x00000100ebd0b0>

大约第 20 行...

 18:   <div class="field">
 19:     <%= f.label :addr1 %><br />
 20:     <%= f.text_field :addr1 %>
 21:   </div>

很容易修复，但我想编写一个 rspec 测试来演示相同的错误（以防我重新引入它）。我已经尝试了很多测试。例如，在我的spec/views/agencies/edit.html.erb_spec.rb中，我目前有......

 require 'spec_helper'
 describe "agencies/edit.html.erb" do
   it "renders the complete form" do
     assign(:agency, Factory(:agency, :name => "pat"))
     render # agencies/edit
     rendered.should match(/pat/)
     rendered.should match(/Editing agency/)
     assert_select "form", :action => agencies_path(@agency), :method => "post" do
       assert_select "input#agency_name", :name => "agency[name]"
       assert_select "input#agency_addr1", :name => "agency[name]"
     end
     puts rendered.to_s
   end
 end

但问题是它通过了！它不会触发我通过浏览器遇到的相同问题。而且，我故意留下了“addr1”的东西……当然，把它拿出来仍然可以。我希望第一次渲染会失败。看跌期权显示...

<div class="field">
  <label for="agency_addr1">Addr1</label><br />
  <input id="agency_addr1" name="agency[addr1]" size="30" type="text" />
</div>

关于如何编写一个规范来显示页面确实可以正确呈现，有什么想法吗？

谢谢帕特

。在探索这一点的过程中，我意识到 :name => “agency[name]”在assert_select 中不执行任何操作。无论我在那里放什么，测试都会通过。这是从生成的代码复制的......对此有什么想法吗？

I have an obvious error in my Rails 3 application. I was in the process of changing a field name from "addr1" to "address" (in my "agency" model). So naturally when I try to pull up the edit page I get the following error.

  undefined method `addr1' for #<Agency:0x00000100ebd0b0>

around line 20...

 18:   <div class="field">
 19:     <%= f.label :addr1 %><br />
 20:     <%= f.text_field :addr1 %>
 21:   </div>

Easy to fix, but I want to write an rspec test that will demonstrate that same error (in case I ever re-introduce it). I have tried a number of tests. For example in my spec/views/agencies/edit.html.erb_spec.rb I currently have...

 require 'spec_helper'
 describe "agencies/edit.html.erb" do
   it "renders the complete form" do
     assign(:agency, Factory(:agency, :name => "pat"))
     render # agencies/edit
     rendered.should match(/pat/)
     rendered.should match(/Editing agency/)
     assert_select "form", :action => agencies_path(@agency), :method => "post" do
       assert_select "input#agency_name", :name => "agency[name]"
       assert_select "input#agency_addr1", :name => "agency[name]"
     end
     puts rendered.to_s
   end
 end

But the problem is that it passes! It does NOT trigger the same problem that I get through the browser. And, I left the "addr1" stuff in on purpose... taking it out still passes of course. I was hoping that the very first render would fail. The puts shows...

<div class="field">
  <label for="agency_addr1">Addr1</label><br />
  <input id="agency_addr1" name="agency[addr1]" size="30" type="text" />
</div>

Any ideas on how I can write an spec that shows me that a page really renders correctly?

thanks

PS. In the process of exploring this I realized that the :name => "agency[name]" does nothing in the assert_select. The test passes no matter what I put there. And this is copied from generated code... any thoughts on that?
