Question

根据Ryan Bates的说法一直在学习Rspec，Capybara和FactoryGirl。＆＃34;我如何测试＆＃34; railscast并遇到障碍。我的应用程序使用Devise进行身份验证，使用CanCan进行授权。我想测试以确保用户可以删除自己的帖子，但不能删除其他用户的帖子，但我似乎无法删除。我已经读过如何使用＆＃34;控制器测试＆＃34;对于这一点，谷歌搜索并没有详细说明它与我的集成测试之间的差异以及我如何走这条路。

这是我的代码，下面是结果：

工厂：

  2 FactoryGirl.define do
  3   factory :role do
  4     factory :admin_role do
  5      name 'admin'
  6     end
  7 
  8     factory :author_role do
  9       name 'author'
 10     end
...
 17   sequence(:name) { |n| "Joe User #{n}"}
 18   sequence(:email) { |n| "joeuser+user#{n}@example.com"}
 19 
 20   factory :user do
 21     name
 22     email
 23     password 'secret'
 24 
 25     factory :admin, :class => User do
 26       name
 27       email
 28       after_create { |user| user.roles << FactoryGirl.create(:admin_role) }
 29     end
 30 
 31     factory :author , :class => User do
 32       name
 33       email
 34       after_create { |user| user.roles << FactoryGirl.create(:author_role) }
 35     end
 36   end
 37 
 38   sequence(:title) { |n| "Post Title #{n}"}
 39   sequence(:body) { |n| "The inner post body #{n}"}
 40 
 41   factory :post do
 42     title
 43     body
 44   end
 45 
 46 end

posts_spec.rb：

  1 require 'spec_helper'                                                                                                                                                                                   
  2 
  3 def login(user)
  4   visit new_user_session_path
  5   fill_in "Email", :with => user.email
  6   fill_in "Password", :with => user.password
  7   click_button "Sign in"
  8   page.should have_content("Signed in successfully")
  9 end
 10 
 11 describe "Posts" do
 12   let(:author) {FactoryGirl.create(:author)}
 13   let(:author2) {FactoryGirl.create(:author)}
 14   let(:user) {FactoryGirl.create(:user)}
 15   let(:admin) {FactoryGirl.create(:admin)}
 16   let(:post) { FactoryGirl.create(:post, user: author) }
...
 99   describe "destroy /post/:id" do
100     it "should allow the author to destroy post" do
101       login(author)
102 
103       visit post_path(post, :method => :delete)
104       lambda {
105         visit post_path(post)                                                                                                                                                                           
106       }.should raise_exception(ActiveRecord::RecordNotFound)
107     end
108   end
109 end

警卫的结果：

Running: spec/requests/posts_spec.rb
........F

Failures:

  1) Posts destroy /post/:id should allow the author to destroy post
     Failure/Error: lambda {
       expected ActiveRecord::RecordNotFound but nothing was raised
     # ./spec/requests/posts_spec.rb:104:in `block (3 levels) in <top (required)>'

当我实际使用save_and_open_page（使用launchy）时，我发现该帖子尚未被删除。关于我应该如何做到这一点的任何想法？非常感谢！

谢谢你，railscard，解决方案：

你真的想通过Capybara测试能力吗？关于测试CanCan的解决方案：github.com/ryanb/cancan/wiki/Testing-Abilities

测试CanCan是否授权使用Rspec，Capybara和FactoryGirl进行破坏方法？
