Rails 3教程第8章集成测试失败

Question

我一直在学习Michael的Rails 3教程。一直持续到第八章的整合测试。我运行了以下命令来创建集成测试：

rails generate integration_test users

它创建了一个文件，然后我添加了两个测试:一个用于失败(空表单)，一个用于成功(实际有效的表单字段)。

下面是上面的命令生成的users_spec.rb文件：

require 'spec_helper'
require 'database_cleaner'

describe "Users" do

  describe "GET /users" do
    it "works! (now write some real specs)" do
      # Run the generator again with the --webrat flag if you want to use webrat methods/matchers
      get users_index_path
      response.status.should be(200)
    end
  end

  describe "signup" do

    describe "failure" do
      it "should not make a new user with empty data" do
        lambda do
          visit signup_path
          fill_in "Name",         :with => ""
          fill_in "Email",        :with => ""
          fill_in "Password",     :with => ""
          fill_in "Confirmation", :with => ""
          click_button
          response.should render_template('users/new')
          response.should have_selector("div#error_explanation")
        end.should_not change(User, :count)
      end #end "should not make a new user with empty data" do
    end #end describe failure

    describe "success" do
      it "should make a new user" do
        lambda do
          visit signup_path
          fill_in "Name",         :with => "Example User"
          fill_in "Email",        :with => "user@example.com"
          fill_in "Password",     :with => "foobar"
          fill_in "Confirmation", :with => "foobar"
          click_button
          response.should have_selector("div.flash.success", :content => "Welcome")
          response.should render_template('users/new')
        end.should change(User, :count).by(1)
      end
    end #end success
  end #end describe signup
end #end describe Users

我不知道为什么，但所有的测试都失败了，虽然它们不应该。我是不是遗漏了一些显而易见的东西？我已经运行了rake :迁移，清除了DB，但我就是不明白。

控制台错误来自：rspec spec/requests/users_spec.rb

谢谢，请提前告知！

Answer 1

你在错误中得到了答案。

1：

undefined local variable or method `users_index_path'

这条路根本不存在。从控制台运行rake routes以获取可用路由的列表。很有可能是users_path。

2和3：

ActionView::Template::Error:
   /Users/jorgezapata/rails_projects/sample_app/app/views/users/new.html.erb:17: syntax error, unexpected tSTRING_BEG, expecting ')'

在第17行的app/view/user/new.html.erb文件中有一个语法错误。

学习读取错误输出。它告诉你你需要知道的一切(通常)。
