Question

我在root_path中定义了routes.rb，我在其他测试中调用了get root_path，但出于某种原因，在test/controllers/application_controller_test.rb中，我在调用{{}时遇到此错误1}}：

get root_path

这是ApplicationControllerTest#test_should_get_index_when_not_logged_in: ActionController::UrlGenerationError: No route matches {:action=>"/", :controller=>"application"} test/controllers/application_controller_test.rb:10:in `block in <class:ApplicationControllerTest>'

routes.rb

这是Rails.application.routes.draw do root 'application#index' get 'signup' => 'users#new' get 'login' => 'sessions#new' post 'login' => 'sessions#create' delete 'logout' => 'sessions#destroy' resources :users resources :account_activations, only: [:edit] resources :password_resets, only: [:edit, :new, :create, :update] resources :lessons, only: [:show, :index] do resources :pre_lesson_surveys, shallow: true, except: :destroy end end

application_controller.rb

这是class ApplicationController < ActionController::Base protect_from_forgery with: :exception include SessionsHelper def index render 'admin_home_page' if admin? render 'user_home_page' if logged_in? @user = User.new unless logged_in? end end

中的一个

tests

我确定我只是在做一些愚蠢的事，但我不能把手指放在上面

如果要确保在对根路径的请求中呈现index模板，请求规范可能是合适的：

spec/requests/application_requests_spec.rb：

describe "Test Root Path" do
  it 'successfully renders the index template on GET /' do
    get "/"
    expect(response).to be_successful
    expect(response).to render_template(:index)
  end
end

如果您想确保index模板在对ApplicationController的索引操作的请求中呈现，则控制器规范可能是合适的。

spec/controllers/application_controller_spec.rb：

describe ApplicationController do
  describe "GET index" do
    it "successfully renders the index template" do
      expect(controller).to receive(:index)
      get :index
      expect(response).to be_successful
      expect(response).to render_template(:index)
    end
  end
end

GETting root_path时没有路由错误，但只在我的一些测试中出错
