Minitest - 在Rails 4中測試ApplicationController before_action

Question

如何在Minitest中測試ApplicationController before_action？我有一個before_action設置url params的語言環境，但我不知道如何爲它設置測試。

您可以通過設置一個匿名控制器並將spec請求路由到該控制器來完成。

下面是一個例子：

require 'test_helper' 

class BaseController < ApplicationController 
    def index 
    render nothing: true 
    end 
end 

class BaseControllerTest < ActionDispatch::IntegrationTest 
    test 'redirects if user is not logedin' do 
    Rails.application.routes.draw do 
     get 'base' => 'base#index' 
    end 

    get '/base' 

    assert_equal 302, status 
    assert_redirected_to 'http://example.com/login' 
    Rails.application.routes_reloader.reload! 
    end 

    test 'returns success if user is loggedin' do 
    Rails.application.routes.draw do 
     get 'base' => 'base#index' 
    end 

    mock_auth! 

    get '/base' 
    assert_equal 200, status 
    Rails.application.routes_reloader.reload! 
    end 
end
