Ruby on Rails 3 - Devise/Omniauth 测试失败：没有路由匹配 {：controller=> "omniauth_callbacks" ， ：action=>

Question

我在rails 3.2.11下使用design2.2.0和omniauth 1.1.1。

我有一个测试在一个未认证(例如没有"before_filter:authenticate_user!")控制器名为"HomepageController"与一个名为"主页"的动作。这个控制器动作非常简单，除非用户登录，否则它会传递到它的视图，在这种情况下，它会重定向到我们的"主页"页面。下面是控制器动作:

class HomepageController < ApplicationController
  def homepage
if current_user then
  redirect_to :homebase
end
  end
end

下面是我的测试:

require 'test_helper'
class HomepageControllerTest < ActionController::TestCase
  def setup
    @user = users(:donley)
  end
  test "should get homepage when signed in" do
    sign_in @user
    get :homepage
    assert_redirected_to "/homebase"
  end
  test "should get homepage when not signed in" do
    get :homepage
    assert_response :success
  end
end

第二个测试失败，出现以下错误:

No route matches {:controller=>"omniauth_callbacks", :action=>"passthru", :provider=>:facebook}

在视图的这一行:

= link_to user_omniauth_authorize_path(:facebook) do

这里是我的设计和全功能路由:

  resources :oauth_clients
  match '/oauth/test_request',  :to => 'oauth#test_request',  :as => :test_request
  match '/oauth/token',         :to => 'oauth#token',         :as => :token
  match '/oauth/access_token',  :to => 'oauth#access_token',  :as => :access_token
  match '/oauth/request_token', :to => 'oauth#request_token', :as => :request_token
  match '/oauth/authorize',     :to => 'oauth#authorize',     :as => :authorize
  match '/oauth',               :to => 'oauth#index',         :as => :oauth
  devise_for :users, :controllers => {:omniauth_callbacks => "omniauth_callbacks"}
  devise_scope :user do
    get "sign_in", :to => "devise/sessions#new"
    get "sign_up", :to => "devise/registrations#new"
    match "sign_out", :to => "devise/sessions#destroy"
  end

这是rake routes的路由，看起来像错误消息中提到的路由:

user_omniauth_authorize /users/auth/:provider(.:format) omniauth_callbacks#passthru {:provider=>/facebook|linkedin/}

真正疯狂的是，所有这些代码在我的生产环境中运行在rails server或Heroku上时都能完美地工作。只有在测试中失败。

非常感谢任何见解!

我今天遇到了同样的问题，发现我没有在测试环境中添加Facebook作为提供者。这应该在devise.rb初始化器中完成。我猜这就是运行测试时没有生成路由的原因。

#config/initializers/devise.rb
if Rails.env.test?
  config.omniauth :facebook, "APP_ID", "APP_SECRET"
end
