使用Rspec + Capybara在Rails中测试错误页面 [英] Testing error pages in Rails with Rspec + Capybara

问题描述

在Rails 3.2.9中，我具有如下自定义错误页面：

 ＃application.rb 
 config .exceptions_app = self.routes 
 
＃route.rb 
 match'/ 404'=> ‘errors＃not_found’
  

其工作原理与预期的一样。当我在 development.rb 中设置 config.consider_all_requests_local = false 时，会得到 not_found 访问 / foo

时的视图

但是我该如何使用Rspec + Capybara进行测试？ / p>

我已经尝试过：

 ＃/ spec / features / not_found_spec.rb 
要求'spec_helper'
描述'未找到的页面'做
它'应该以404页面响应'做
访问'/ foo'
页面。当我跑步时，
结束
结束
  

我得到的这个规范：

  1）找不到页面应以404页面
响应失败/错误：访问'/ foo'
 ActionController :: RoutingError：
没有路由匹配[GET] / foo 
  

我该如何测试？

编辑：

忘记了提及：我已经在 test.rb

$ b中设置了 config.consider_all_requests_local = false $ b

解决方案

test.rb 中有问题的设置不仅是

  consider_all_requests_local = false 
  

而且

  config.action_dispatch.show_exceptions = true 
  

如果设置此项，您应该能够测试错误。
我无法在周围过滤器中使用它。

测试

In Rails 3.2.9 I have custom error pages defines like this:

# application.rb
config.exceptions_app = self.routes

# routes.rb
match '/404' => 'errors#not_found'

Which works like expected. When I set config.consider_all_requests_local = false in development.rb I get the not_found view when visiting /foo

But how do I test this with Rspec + Capybara?

I've tried this:

# /spec/features/not_found_spec.rb
require 'spec_helper'
describe 'not found page' do
  it 'should respond with 404 page' do
    visit '/foo'
    page.should have_content('not found')
  end
end

When I run this spec I get:

1) not found page should respond with 404 page
  Failure/Error: visit '/foo'
  ActionController::RoutingError:
    No route matches [GET] "/foo"

How can I test this?

Edit:

Forgot to mention: I've set config.consider_all_requests_local = false in test.rb

解决方案

The problematic setting in the test.rb is not only the

consider_all_requests_local = false

but also

config.action_dispatch.show_exceptions = true

If you set this you should be able to test the error. I was not able to use it in an around filter.
