【问题描述】：
我在 Michael Hartl 的 Ruby on Rails 3 教程（本书的 Kindle 早期版本，而不是在线版本）的第 9 章结束时遇到了失败的集成测试 (users_spec.rb)。我一直在寻找一段时间，但到目前为止我发现的建议都没有对我有用。我下载了第一版和第二版教程的源代码，它们运行良好，所以看起来我的应用程序配置有问题，但作为一个rails新手，感觉就像大海捞针所以欢迎任何帮助。
错误信息：ActionController::RoutingError: No route matches [GET] "/signout"
users_spec.rb 包含这个
...
describe "success" do
it "should sign a user in and out" do
user = FactoryGirl.create(:user)
visit signin_path
fill_in :email, :with => user.email
fill_in :password, :with => user.password
click_button
controller.should be_signed_in
click_link "Sign out"
controller.should_not be_signed_in
end
end
...
我的 application.html.erb 看起来像这样
<!DOCTYPE html>
<html>
<head>
<title><%= @title %></title>
<%= javascript_include_tag 'default' %>
<%= csrf_meta_tags %>
<%= render 'layouts/stylesheets' %>
</head>
<body>
<div class='container'>
<%= render 'layouts/header' %>
<section class = "round">
<% flash.each do |key, value| %>
<div class="flash <%= key %>"><%= value %></div>
<% end %>
<%= yield %>
</section>
<%= render 'layouts/footer' %>
<%= debug(params) if Rails.env.development? %>
</div>
</body>
</html>
我的 application_controller.rb 看起来像这样
class ApplicationController < ActionController::Base
protect_from_forgery
include SessionsHelper
end
我的 application.js 看起来像这样
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// the compiled file.
//
// WARNING: THE FIRST BLANK LINE MARKS THE END OF WHAT'S TO BE PROCESSED, ANY BLANK LINE SHOULD
// GO AFTER THE REQUIRES BELOW.
//
//= require jquery
//= require jquery_ujs
//= require_tree .
_header.html.erb 文件包含此内容
...
<% if signed_in? %>
<li><%= link_to "Sign out", signout_path, :method => :delete %></li>
<% else %>
...
我的 routes.rb 包含这个
...
get "sessions/new"
resources :users
resources :sessions, :only =>[:new, :create, :destroy]
match '/contact', :to => 'pages#contact'
match '/about', :to => 'pages#about'
match '/help', :to => 'pages#help'
match '/signup', to: 'users#new'
match '/signin', to: 'sessions#new'
match '/signout', to: 'sessions#destroy', via: :delete
root :to => 'pages#home'
...
我的 session_controller.rb 包含这个
...
def destroy
sign_out
redirect_to root_path
end
...
sessions_helper.rb 包含这个
...
def sign_out
cookies.delete(:remember_token)
@current_user = nil
end
...
这是我执行 rake 路由时得到的结果
sessions_new GET /sessions/new(.:format) sessions#new
users GET /users(.:format) users#index
POST /users(.:format) users#create
new_user GET /users/new(.:format) users#new
edit_user GET /users/:id/edit(.:format) users#edit
user GET /users/:id(.:format) users#show
PUT /users/:id(.:format) users#update
DELETE /users/:id(.:format) users#destroy
sessions POST /sessions(.:format) sessions#create
new_session GET /sessions/new(.:format) sessions#new
session DELETE /sessions/:id(.:format) sessions#destroy
contact /contact(.:format) pages#contact
about /about(.:format) pages#about
help /help(.:format) pages#help
signup /signup(.:format) users#new
signin /signin(.:format) sessions#new
signout DELETE /signout(.:format) sessions#destroy
我的 gemfile 看起来像这样
source 'https://rubygems.org'
gem 'rails', '3.2.8'
gem 'pg'
gem 'gravatar_image_tag'
gem 'jquery-rails'
group :development do
gem 'rspec-rails'
gem 'annotate'
end
group :test do
gem 'rspec'
gem 'webrat'
gem 'spork'
gem 'factory_girl_rails'
end
当运行 bundler install 时，我得到这个输出：
Using rake (0.9.2.2)
Using i18n (0.6.1)
Using multi_json (1.3.6)

Using spork (0.9.2)
Using webrat (0.7.3)
值得一提的是，当通过 rails 运行我的应用程序时，它也会失败，因此这不仅仅是 webrat 或集成失败的问题。在 firbug 中查看 html 源代码时，它表明我希望显示的 javascript 不存在
<script type="text/javascript" src="/assets/jquery.js?body=1">
<script type="text/javascript" src="/assets/jquery_ujs.js?body=1">
当点击“退出”时，这是结果
【问题讨论】：

就您所展示的内容而言，我没有发现任何问题。照常做，清除浏览器缓存，安装包，重启服务器，看看是否可行。
-
在您的
user_spec文件中，水豚如何知道您要使用此代码单击哪个按钮：click_button？指定按钮的 id、文本或值，然后重试 -
哇，我才意识到你甚至没有使用水豚
-
确实，我正在使用 webrat。我很快尝试切换到 capybara，但由于我猜的语法差异，导致 23 次测试失败（包括这篇文章所涉及的测试）。因此，在将所有这些测试调整为 capybara 语法之前，我想确保这个测试是成功的。
-
如果你还没有意识到，你不应该使用 rails 3.2 来学习 3.0 教程，以避免不必要的挫折。
