测试覆盖设计的控制器 - “无路由匹配”

Question

我跑rails g devise:controllers users和我的路线看起来像

devise_for :users, controllers: { 
    sessions: 'sessions' 
} 

我有一个app/controllers/users/sessions_controller，我想测试。我的路线是这样的：

$ rake routes 
       Prefix Verb URI Pattern     Controller#Action 
    new_user_session GET /users/sign_in(.:format)  sessions#new 
     user_session POST /users/sign_in(.:format)  sessions#create 

我建立了我的测试是这样的：

# test/controllers/users/sessions_controller_test.rb 
require 'test_helper' 

class SessionsControllerTest < ActionController::TestCase 
    tests Users::SessionsController 

    test "sign in sanity check" do 
    user = users(:one) 
    post :create, email: user.email, password: 'password' 
    assert_response :success 
    end 
end 

哪个失败，出现错误：

ActionController::UrlGenerationError: No route matches {:action=>"create", :controller=>"users/sessions", :email=>"one@example.com", :password=>"password"} 

如何正确发送到我想要的网址？我尝试了各种各样的变化，但我在这里错过了一些魔术酱。

你的routes.rb更改为

devise_for :users, controllers: { 
    sessions: 'users/sessions' 
} 

并在测试，确保你有

class SessionsControllerTest < ActionController::TestCase 
    tests Users::SessionsController 
    include Devise::TestHelpers 

    test "sign in sanity check" do 
    request.env["devise.mapping"] = Devise.mappings[:user] 
    user = users(:one) 
    post :create, email: user.email, password: 'password' 
    assert_response :success 
    end 
end 

（你可以see how Devise itself does it的例子。）
