使用 RSpec2 和 Rails3.0.4，如何从 XML 测试像 admin_controller.rb 这样的通用控制器

发布于 2024-10-18 05:38:11 字数 11326 浏览 0 评论 0原文

这是什么问题

我想测试一个 before 过滤器，如果失败，它会在 XML 和 JSON 中呈现错误， 。 当从经典控制器测试它时，它工作得很好，当从 ApplicationController 直接失败。

代码的精简版

specs/controller/admin_controller_spec.rb

require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')

describe AdminController do
  controller(AdminController) do
    def index
      render :text => 'ok'
    end
  end

  it "should include errors properly formated" do
    get :index, :format => 'xml'
    response.body.should == "block"
  end
end

app/controller/admin_controller.rb

class AdminController < ApplicationController
  before_filter :block_something

  protected

    def block_something
      respond_to do |wants|
        wants.xml {
          render :text => 'block' 
        }
      end
    end
end

测试错误

Failure/Error: get :index, :format => format
  TypeError:
    can't convert nil into String

更新，其中backtrace ：感谢 Ryan Bigg 的推荐

它提供了与上面示例不同的控制器和过滤器名称。该应用程序使用 admin_controller.rb 和 block_suspended 过滤器。

有想过为什么要附加这个吗？如果不是正确的测试方法，如何测试这种行为？

原文

What's the problem

I wanna test a before filter that render errors in XML and JSON if failing.
When testing it from a classic controller it works fine, when testing from
the ApplicationController directly it fails.

A light version of the code

specs/controller/admin_controller_spec.rb

require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')

describe AdminController do
  controller(AdminController) do
    def index
      render :text => 'ok'
    end
  end

  it "should include errors properly formated" do
    get :index, :format => 'xml'
    response.body.should == "block"
  end
end

app/controller/admin_controller.rb

class AdminController < ApplicationController
  before_filter :block_something

  protected

    def block_something
      respond_to do |wants|
        wants.xml {
          render :text => 'block' 
        }
      end
    end
end

Error from tests

Failure/Error: get :index, :format => format
  TypeError:
    can't convert nil into String

Update, with backtrace : thanks Ryan Bigg for the recommendation

It gives different controller and filter names than the example above. The app use admin_controller.rb and block_suspended filter.

Any thought on why this appends? If not the right way to test it, how to test such behavior?

我现在已升级到 ruby​​ 1.9.2，所有规格均通过，无需任何更改。

看起来像是 Ruby 1.8.7 的限制，需要额外的解决方法。

I've now upgraded to ruby 1.9.2 and all specs passes without any changes required.

Looks like a limitation of Ruby 1.8.7 that would need extra workarounds.
