rspec before_filters失败

Question

我是Rails新手，我使用的是Boti's evolved way to test my project，但是我得到了以下错误：

> Failures:

  1) ApplicationController UploadsController admin_only should filter :before and {:with=>:admin_only, :except=>:show}
     Failure/Error: extra = -> (x) { x.options[:unless].include?( "action_name == '#{filter[:except]}'") }

     NoMethodError:
       undefined method `options' for #<ActiveSupport::Callbacks::Callback:0x000006060f6598>
     # ./spec/support/matchers/filter.rb:5:in `block (3 levels) in <top (required)>'
     # ./spec/support/matchers/filter.rb:9:in `call'
     # ./spec/support/matchers/filter.rb:9:in `block (3 levels) in <top (required)>'
     # ./spec/support/matchers/filter.rb:9:in `find'
     # ./spec/support/matchers/filter.rb:9:in `block (2 levels) in <top (required)>'
     # ./spec/controllers/application_controller_spec.rb:37:in `block (4 levels) in <top (required)>'

有人能帮我解决这件事吗谢谢。

这是我的规范：

RSpec.describe ApplicationController, type: :controller do
  include Devise::Test::ControllerHelpers
       describe UploadsController do
        context 'authentication' do
         specify{ expect(UploadsController).to filter(:before, with: :authenticate_user!)}
        end
        context 'admin_only' do
         specify{ expect(UploadsController).to filter(:before, with: :admin_only, except: :index)}
        end
      end
   end

这是控制器

class UploadsController < ApplicationController
   before_action :authenticate_user!
   before_action :admin_only, :except => :index
   def index
    begin
      @uploads = Upload.all
    rescue
      redirect_to uploads_alert_uploads_path(:error_path => request.url, :error_time => DateTime.now)
    end
  end
end

这是spec/support/matchers/filter.rb中的matcher

RSpec::Matchers.define :filter do |kind, filter|
  match do |controller|
    extra = -> (x) {true}
    if filter[:except].present?
      extra = -> (x) { x.options[:unless].include?( "action_name == '#{filter[:except]}'") }
    elsif filter[:only].present?
      extra = -> (x) { x.options[:if].include?( "action_name == '#{filter[:only]}'") }
    end
    controller._process_action_callbacks.find{|x|x.kind == kind && x.filter == filter[:with] && extra.call(x)}
  end
end

更好的测试是断言用户不能访问UploadsController (请求返回404)，管理员可以访问(请求返回200)。

断言调用过滤器将您的测试与admin_only方法的实现联系在一起，而不是限制用户可以访问的内容的最终结果。
