如何在 Rails 5 控制器测试中测试或绕过 Basic Auth

How to test or bypass Basic Auth in Rails 5 testing of controllers

我想测试 Rails 5 中激活了基本身份验证的控制器。 current official instruction(截至 2018-10-14)中解释的方式由于某种原因不起作用。 问答“”对于 Rails 5(至少对于默认值而言)似乎太旧了。

这是一个重现案例的简化示例。
我从全新安装的 Rails(最新稳定版 5.2.1):

通过脚手架制作了文章模型和相关资源
bin/rails g scaffold Article title:string content:text

并在控制器中添加了基本的身份验证功能,继official guide之后;那么 ArticlesController 就是这样的,当然可以:

# /app/controllers/articles_controller.rb
class ArticlesController < ApplicationController
  http_basic_authenticate_with name: "user1", password: "pass"
  before_action :set_article, only: [:show, :edit, :update, :destroy]

  def index
    @articles = Article.all
  end
end

official instruction说明了测试基本认证的方法;你加 request.headers['Authorization'] 在控制器测试文件的 setup 块中,我这样做了:

# /test/controllers/articles_controller_test.rb
require 'test_helper'

class ArticlesControllerTest < ActionDispatch::IntegrationTest
  setup do
    request.headers['Authorization'] =
      ActionController::HttpAuthentication::Basic.encode_credentials("user1", "pass")
    @article = articles(:one)
  end

  test "should get index" do
    get articles_url
    assert_response :success
  end
end

然而,bin/rails test 失败如下:

# Running:

E

Error:
ArticlesControllerTest#test_should_get_index:
NoMethodError: undefined method `headers' for nil:NilClass
    test/controllers/articles_controller_test.rb:5:in `block in <class:ArticlesControllerTest>'

bin/rails test test/controllers/articles_controller_test.rb:10

显然,request 方法 returns 为零,因此 request.headers['Authorization'] 失败。如果将语句放在 'testing-index' 块的顶部,则相同。

我发现 request returns 一个合适的值 get articles_url 是 运行 之后,但是为时已晚那时;我的意思是,到那时身份验证已经失败(很明显)。通过一些谷歌搜索,似乎有些人使用 @request@response 来代替,但我也发现它们与 request 完全相同(预期?),即是,它们在 get.

之前为零

在Rails5中控制器测试或集成测试中绕过或测试Basic Auth的方法是什么?

编辑:
"current official instruction (as of 2018-10-14)" is apparently wrong. See .

测试文档 were incorrect and have been updated but not yet released. The updated docs 阅读:

NOTE: If you followed the steps in the Basic Authentication section, you'll need to add authorization to every request header to get all the tests passing:

post articles_url, params: { article: { body: 'Rails is awesome!', title: 'Hello Rails' } }, headers: { Authorization: ActionController::HttpAuthentication::Basic.encode_credentials('dhh', 'secret') }
