如何用嵌套路線測試控制器？

Question

請幫忙解決這個問題。我需要爲索引操作測試渲染模板。

routes.rb中：

resources :users do 
    resources :albums 
end 

耙路線：

user_albums GET /users/:user_id/albums(.:format)    albums#index 

相冊控制器：

class AlbumsController < ApplicationController 
    before_action :set_album, only: [:show, :edit, :update, :destroy, :get_album_data] 

    def index 
    @user = User.find(params[:user_id]) 
    @albums = @user.albums.paginate(page: params[:page], :per_page => 6).order(created_at: :DESC) 
    @album = Album.new 
    end 

    ......... 
    ......... 

    private 
    def set_album 
     @album = Album.find(params[:id]) 
    end 

    def album_params 
     params.require(:album).permit(:title, :description) 
    end 
end 

albums_controller_spec.rb：

require 'spec_helper' 

    describe AlbumsController do 
     describe 'index action' do 
     it 'render index template if user is found' do 
      user = FactoryGirl.create(:user) 
      get :index, { user_id: user.id } 
      response.should render_template('index') 
     end 
     end 
    end 

個

工廠：

FactoryGirl.define do 
    factory :user do 
    name 'qqq' 
    sequence(:email){ |i| "use#{i}@ad.ad" } 
    password 'qwerty' 
    password_confirmation{ |u| u.password } 
    end 
end 

我在控制檯中運行它：

rake db:reset RAILS_ENV=test 
rspec spec 

控制檯顯示以下錯誤信息：

F. 

Failures: 

    1) AlbumsController index action render index template if user is found 
    Failure/Error: get :index, { user_id: user.id } 
    NoMethodError:

Failed examples:

請幫我 '指數' 測試動作

Answer 1

您正在收到的當前錯誤

undefined method `get' for #<RSpec::ExampleGroups::AlbumsController 

是因爲您需要指定您的規格作爲類型爲：：controller的控制器規格。

describe AlbumsController, type: :controller do
