Question

您好我正在完成Hartl的Ruby on Rails教程，我在第9.1章中遇到了一个失败的测试。当我在终端中运行spec时，它返回：

sis-macbook-pro:sample_app Lagaspi$ bundle exec rspec spec/
...............................F................................

Failures:

1) AuthenticationPages signin with valid information 
 Failure/Error: it { should have_link('Users',       href: users_path) }
   expected link "Users" to return something
 # ./spec/requests/authentication_pages_spec.rb:37:in `block (4 levels) in <top (required)>'

Finished in 1.42 seconds
64 examples, 1 failure

Failed examples:

rspec ./spec/requests/authentication_pages_spec.rb:37 # AuthenticationPages signin with valid information

这是我的代码 - authentication_pages_spec.rb

require 'spec_helper'

describe "AuthenticationPages" do

subject { page }

describe "signin page" do
before { visit signin_path }

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

describe "signin" do
before { visit signin_path }

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

  it { should have_selector('title', text: '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_selector('title', text: user.name) }
  it { should have_link('Profile',     href: user_path(user)) }
  it { should have_link('Sign out',    href: signout_path) }
  it { should have_link('Settings',    href: edit_user_path(user)) }
  it { should have_link('Users',       href: users_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
end

我认为这就是问题界线（37）：

it { should have_link('Users',       href: users_path) }

但我该怎么办？我是新手，无法弄清楚。谢谢你。

如果你正在学习本教程，那么只有在用户登录时才能看到该链接。当用户登录时，你没有想到任何其他测试失败，即

it { should have_link('Profile',     href: user_path(user)) }
it { should have_link('Sign out',    href: signout_path) }
it { should have_link('Settings',    href: edit_user_path(user)) }

因此，考虑到这一点，我倾向于认为问题在于视图，而不是规范。一目了然，规格看起来很好。

你的_header.html.erb是否包含此内容

...
<% if signed_in? %>
  <li><%= link_to "Users", users_path %></li>
...
