ruby-on-rails - 使用 RSpec 测试 Rails Controller ——如何测试 : current_account. 项目

Question

我正在使用 Rspec 和 Rails 3 进行测试。我已经测试了我的模型和助手，但我不知道如何开始测试 Controller 。我 Controller 操作中的几乎所有数据都是使用以下示例提取的:

@services = current_account.services

@projects = current_person.projects

@projects = current_account.projects.active 
# this is really @projects = current_person.account.projects.active)

我似乎找不到任何示例来说明如何测试以这种方式提取的数据。我发现的所有示例都不限于帐户或个人。谁能给我指点一篇关于如何模拟或 stub 这种类型安排的文章？这是否表明整个方法不正确？下面，我包含了一个完整的示例 Controller 。

如有任何帮助，我们将不胜感激。

谢谢，大卫

class ServicesController < ApplicationController
  # Run authorizations
  filter_resource_access

  # Respond to ...
  respond_to :html, :xml, :json
  respond_to :js,   :only => [:new, :create, :edit, :update, :destroy]

  # GET /services
  # GET /services.xml
  def index
    @services = current_account.services.order("name").paginate(:page => params[:page])

    respond_with(@services)
  end

  # GET /services/1
  # GET /services/1.xml
  def show
    @service = current_account.services.find(params[:id])

    respond_with(@service)
  end

  # GET /services/new
  # GET /services/new.xml
  def new
    @service = current_account.services.new

    respond_with(@service)
  end

  # GET /services/1/edit
  def edit
    @service = current_account.services.find(params[:id])

    respond_with(@service)
  end

  # POST /services
  # POST /services.xml
  def create
    @service = current_account.services.new(params[:service])

    if @service.save
      # flash[:notice] = 'A service was successfully created.'
    end

    respond_with(@service, :location => services_url)
  end

  # PUT /services/1
  # PUT /services/1.xml
  def update
    @service = current_account.services.find(params[:id])

    if @service.update_attributes(params[:service])
      # flash[:notice] = 'The service was successfully updated.'
    end

    respond_with(@service, :location => services_url)
  end

  # DELETE /services/1
  # DELETE /services/1.xml
  def destroy
    @service = current_account.services.find(params[:id])

    if @service.destroy
      flash[:notice]  = "The service was successfully deleted."
    else
      flash[:warning] = @service.errors.full_messages.inject("") { |acc, message| acc += message  }
    end

    respond_with(@service)
  end
end

感谢 Xaid 的解决方案，我能够得到一个解决方案:

  context "logged_in" do
    before(:each) do
      @current_account = Factory.create(:account)
      controller.stub!(:current_account).and_return(@current_account)

      @services = FactoryGirl.create_list(:service, 10, :account => @current_account)
      @services << @current_account.services.first
      @current_account.services.stub!(:all).and_return(@services)
    end


    # INDEX
    describe "GET services" do
      before(:each) do
        get :index
      end

      it "should set @services when accessing GET /index" do
        assigns[:services].should == @services
      end

      it "should respond with success" do
        response.should be_success
      end
    end
  end

Answer 1

你不能用这样的东西来测试你的'index' Action 吗

describe "GET 'index'" do
  before(:each) do
    @user = FactoryGirl.create(:user)
    controller.stub!(:current_user).and_return(@user)
    @services = FactoryGirl.create_list(:service, 10, :user => @user)
    @user.services.stub!(:all).and_return(@services)
  end

  it "should return a list of services" do
    get :index
    assigns(:services).should == @services
  end
end

如果我正确理解了你的问题，你应该能够 stub current_user.services(或项目)并让它返回一些已知值(在我的示例中由 FactoryGirl 生成)并检查它与存储在你的操作中的值(例如，在您的“索引”操作中使用@services)。
