Rails测试未找到 - 未定义的局部变量或方法“响应”

我正在尝试跟随Michael Hartl的Rails 3 tutorial，我遇到了一个我在别处找不到的错误。在Section 9.2.1下，我在尝试为尝试更新个人资料页面的非登录用户运行测试时遇到错误。

describe "submitting to the update action" do
  before { put user_path(user) }
  specify { response.should redirect_to(signin_path) }
end

我得到的错误是“＃（NameError）”的未定义局部变量或方法'响应'。这是对“bundle exec rspec spec /”的回应。当我注释掉违规行时，所有测试都会实例化并通过。我试过用“response.body”和“page”之类的东西取代“回复”，但似乎都没有帮助。

我不确定问题是什么，因为当我继续学习本教程时，类似的块正在顺利通过。

这是完整的错误文本：

我很确定这不是一个错字，但这里是违规文件（authentication_pages_spec.rb）。 （have_title（）是我在这里找到的修复错误的方法，因为显然has_selector（'title'，...）不再是有效的语法。）

require 'spec_helper'

describe "Authentication" do

  subject { page }

  describe "signin page" do
    before { visit signin_path }

    it {should have_selector('h1', text: 'Sign in') }
    it {should have_title('Sign in') }
  end

  describe "signin" do
    before { visit signin_path }

    describe "with invalid information" do
      before { click_button "Sign in" }

      it { should have_title('Sign in') }
      it { should have_selector('div.alert.alert-error', text: 'Invalid') }

      describe "after visiting another page" do
        before { click_link "Home" }
        it { should_not have_selector('div.alert.alert-error') }
      end
    end

    describe "with valid information" do
      let(:user) { FactoryGirl.create(:user) }
      before { sign_in user }

      it { should have_title(user.name) }
      it { should have_link('Profile', href: user_path(user)) }
      it { should have_link('Settings', href: edit_user_path(user)) }
      it { should have_link('Sign out', href: signout_path) }
      it { should_not have_link('Sign in', href: signin_path) }

      describe "followed by signout" do
        before { click_link "Sign out" }
        it { should have_link('Sign in') }
      end
    end
  end

  describe "authorization" do

    describe "for non-signed-in users" do
      let(:user) { FactoryGirl.create(:user) }

      describe "in the Users controller" do

        describe "visiting the edit page" do
          before { visit edit_user_path(user) }
          it { should have_title('Sign in') }
        end

        describe "submitting to the update action" do
          before { put user_path(user) }
          specify ( response.should redirect_to(signin_path) )
        end

        describe "as wrong user" do
          let(:user) { FactoryGirl.create(:user) }
          let(:wrong_user) { FactoryGirl.create(:user, email: "wrong@example.com") }
          before { sign_in user }

            describe "visiting Users#edit_page" do
              before { visit edit_user_path(wrong_user) }
              it { should_not have_title(full_title("Edit user")) }
            end

            describe "submitting a PUT request to the Users#update action" do
              before { put user_path(wrong_user) }
              specify { response.should redirect_to(root_path) }
            end
         end
      end
    end
  end

答案 0 :(得分：2)

你在运行什么版本的Capybara？ 

$ bundle exec gem list | grep capybara

如果你正在运行版本>= 2.0，你应该再次查看你的Gemfile，并特别标记版本与教程（1.1.2）相同。

<强>的Gemfile 

group :test do
  gem 'capybara', '1.1.2'
end

如果拼命想要使用最新版本，则必须进行一些更改，如以下StackOverflow Q＆amp; As中所述：

更新

好的，你会自己踢，但在克隆你的回购并得到同样的错误后，你的问题很明显（语法高亮是你的朋友）：

在Line 77 of your spec/requests/authentication_pages_spec.rb上你有：

specify ( response.should redirect_to(signin_path) )

应该是：

specify { response.should redirect_to(signin_path) }

修好后，你的考试就会通过。
