Question

我正在尝试测试我的控制器，以便从未注册用户进行访问。我使用devise（3.3.0）和rspec（3.0.0）。

spec/controllers/dares_controller_spec.rb

require 'rails_helper'

describe DaresController do
  let(:challenger) { create(:user) }
  let(:acceptor) { create(:user) }
  let(:challenge) { create(:challenge) }
  let(:dare) { create(:dare) }
  let(:user) { create(:user) }

  describe 'Guest access to dares' do

    describe 'GET #show' do
      it "redirects to root" do
        get :show, id: dare.id, challenge_id: challenge.id
        expect(response).to require_login
      end
    end
  end
end

在控制器中：

dares_controller.rb

before_action :authenticate_user!

  def show

  end

我收到以下错误：

Failures:

  1) DaresController Guest access to dares GET #show redirects to root
     Failure/Error: get :show, id: dare.id, challenge_id: challenge.id
     NoMethodError:
       undefined method `authenticate!' for nil:NilClass
     # ./spec/controllers/dares_controller_spec.rb:16:in `block (4 levels) in <top (required)>'

我尝试添加

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
end

到我的spec_helper / rails_helper但它没有解决问题。我用Google搜索了几个小时的解决方案，两者似乎都有所帮助。

匹配器 - require_login

RSpec::Matchers.define :require_login do |expected|
  match do |actual|
    expect(actual).to redirect_to Rails.application.routes.url_helpers.new_user_session_path
  end

  failure_message do |actual|
    "expected to require login to access the method"
  end

  failure_message_when_negated do |actual|
    "expected not to require login to access the method"
  end

  description do
    "redirect to the login form"
  end
end

更改此行：

描述DaresController做

到这一个：

RSpec.describe DaresController，输入:: controller do

由于您将spec_helper或rails_helper配置为：

config.include Devise::TestHelpers, type: :controller

您应该设置正确的规范type才能正常工作。它是rspec~3中的rspec行为

Devise和Rspec - 未定义的方法`authenticate！＆＃39;为零：NilClass
