ruby-on-rails - Minitest - 在 Rails 4 中测试 ApplicationController before_action

Question

如何在 Minitest 中测试 ApplicationController before_action？我有一个 before_action 从 url params 设置语言环境，但我不知道如何为它设置测试。

您可以通过设置匿名 Controller 并将规范请求路由到该 Controller 来实现。

下面是一个例子:

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
