Ruby on rails 3.2 使用RSpec为ActiveAdmin编写控制器和功能规格？

如何为以下ActiveAdmin代码编写控制器和功能规范：

# app/admin/organization.rb
ActiveAdmin.register Organization do
  batch_action :approve do |selection|
    Organization.find(selection).each {|organization| organization.approve }
    redirect_to collection_path, notice: 'Organizations approved.'
  end
end

这是我的功能规范。它在弹出菜单中找不到ActiveAdmin加载的“批处理操作”

# spec/features/admin/organization_feature_spec.rb
require 'spec_helper'
include Devise::TestHelpers

describe 'Admin Organization' do
  before(:each) do
    @user = FactoryGirl.create(:admin_user)
    login('admin@company.com', 'password1')
  end

  it 'approves in batch' do
    organization = FactoryGirl.create(:organization)
    visit admin_organizations_path
    check 'collection_selection_toggle_all'
    click_link 'Batch Actions'
    click_link 'Approve Selected'
    organization.reload
    organization.state.should eq 'approved'
  end
end

版本

• 轨道3.2.14
• ActiveAdmin 0.6.0

我想出了如何构建控制器规范

# spec/controllers/admin/organizations_controller_spec.rb
require 'spec_helper'
include Devise::TestHelpers

describe Admin::OrganizationsController do
  render_views

  before(:each) do
    @user = FactoryGirl.create(:admin_user)
   sign_in @user
  end

  it 'approve organization' do
    @organization = FactoryGirl.create(:organization, state: 'pending')
    post :batch_action, batch_action: 'approve', collection_selection_toggle_all: 'on', collection_selection: [@organization.id]
    @organization.reload
    @organization.pending?.should be_false
  end
end
