Rspec 测试惨遭失败

Question

所以我在这里看到了几个与我的问题有些相似的问题，但还不够接近，无法帮助我弄清楚我的问题是什么......所以任何关于我做错了什么的帮助将不胜感激：（我我正在关注 Michael Hartl 的教程，因此有关我如何偏离他的示例的信息将特别有帮助）...谢谢

<% provide(:title, "Edit user") %> 
<h1>Update your profile</h1>

<div class="row">
  <div class="span6 offset3">
    <%= form_for(@user) do |f| %>
      <%= render 'shared/error_messages' %>

      <%= f.label :name %>
      <%= f.text_field :name %>

      <%= f.label :email %>
      <%= f.text_field :email %>

      <%= f.label :password %>
      <%= f.password_field :password %>

      <%= f.label :password_confirmation, "Confirm Password" %>
      <%= f.password_field :password_confirmation %>

      <%= f.submit "Save changes", class: "btn btn-large btn-primary" %>
    <% end %>

  </div>
</div>

对于正确修复的任何和所有帮助将不胜感激。谢谢，

Answer 1

put, get, post, delete 和那些用于控制器测试的方法在功能测试中不可用。

在编写功能测试时，您应该通过按钮操作/ajax/etc...“提交”put，而不是像控制器测试那样发布到控制器。

Answer 2

问题是：你把请求 (capybara) 测试和功能测试搞混了。

在capybara 中，您应该描述用户步骤

require 'spec_helper'

describe "Website access" do
  context "when I am a registered user" do
    it "should let me in" do
      page.fill_in 'Email',    with: 'vader@deathstar.com'
      page.fill_in 'Password', with: 'mydearluke'
      page.click_link 'Let me in'

      page.should have_content('Welcome, cheif!')
    end
  end

  context "when I am not a registered user" do
    it "should not let me in" do
      page.fill_in 'Email',    with: 'jabba.h@tatooine.com'
      page.fill_in 'Password', with: 'wormsarmageddon'
      page.click_link 'Let me in'

      page.should have_content('Incorrect credentials!')
    end
  end      
end

功能测试在较低级别运行，因为您需要使用 HTTP 动词 put、get、post、delete 与您正在测试的应用程序进行通信。

require 'spec_helper'

describe SessionsController do
  context "when I am registered user" do
    it "should let me in" do
      post :create, email: 'vader@deathstar.com', password: 'mydearluke'

      response.should be_success
    end
  end

  context "when I am not a registered user" do
    it "should not let me in" do
      post :create, email: 'jabba.h@tatooine.com', password: 'wormsarmageddon'

      response.should_not be_success
    end
  end      
end

这里有几点需要注意：

1. 我使用的是post，而不是put。
2. 我在 describe 块中指定控制器名称，这与 capybara 测试中的简单英语描述形成对比。
3. 功能测试指定SessionController 应该如何准确地响应不同的用户凭据（它应该为一个好的用户创建一个会话，并对一个未注册的用户大喊大叫）。

您要做的是在 request (capybara) 测试中使用 functional 测试中的动词。这是错误的。

回顾：

1. 在capybara 测试中使用visit 和click_link/click_button。
2. 在功能测试中使用 HTTP 动词（put、get、post、delete）。
3. 使用devise gem 进行用户身份验证。

Answer 3

如果您遵循 Rails 教程，则需要将 Capybara 版本降级到 1.1.2 并将您的规范移动到 spec/requests 目录。更新您的 Gemfile：

gem 'capybara', '1.1.2'

如果您打算使用 Capybara 2.0，我建议您阅读以下内容：
