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從url params設置locale但我不知道如何為它設置測試。

Answer 1

您可以通過設置匿名控制器並將規范請求路由到該控制器來實現。

這是一個例子：

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
