首先它基于Rails 3 on Action所以，我会输入我尝试过的所有内容和我遇到的错误，所以任何人都可以帮助我，如果有任何重要文件我应该添加到我的问题中请告诉...也许问题的标题不够好，但我不知道我应该给黄瓜问题什么标题。
在本书中，作者试图隐藏编辑和删除链接，因此非签名用户和登录用户将无法看到它，除非他们是管理员。
用于身份验证他正在使用设计1.4.3和黄瓜版本1.0.6，我在第7章专门针对7.3.3。
现在书中的步骤说我们将对黄色测试进行隐藏编辑和删除链接，这就是它的代码：hidden_links.feature
Scenario: Edit project link is hidden for non-signed-in users
Given I am on the homepage
When I follow "TextMate 2"
Then I should not see the "Edit Project" link
Scenario: Edit project link is hidden for signed-in user
Given I am signed in as "user@ticketee.com"
When I follow "TextMate 2"
Then I should not see the "Edit Project" link
Scenario: Edit project link is shown to admin
Given I am signed in as "admin@ticketee.com"
When I follow "TextMate 2"
Then I should see the "Edit Proeject" link
Scenario: Delete project link is hidden for non-signed-in users
Given I am on the homepage
When I follow "TextMate 2"
Then I should not see the "Delete Project" link
Scenario: Delete project link is hidden for signed-in users
Given I am signed in as "user@ticketee.com"

Then I should not see the "Delete Project" link
Scenario: Delete project link is shown to admins
Given I am signed in as "admin@ticketee.com"
When I follow "TextMate 2"
Then I should see the "Delete Project" link
然后当试图运行测试我有一个关于缺少功能的问题（虽然在书中测试正在通过，然后应该推到github但对我来说它没有通过）所以我已添加在我的顶部代码：
Feature: Hidden Links
In order to clean up the user experience
As the system
I want to hide links from users who can't act on them
现在，当我尝试运行测试时，我收到此错误：

Using the default profile...

You can implement step definitions for undefined steps with these snippets:
Then(/^I should not see the "(.*?)" link$/) do |arg1|
pending # express the regexp above with the code you wish you had
end
Given(/^I am signed in as "(.*?)"$/) do |arg1|
pending # express the regexp above with the code you wish you had
end
Then(/^I should see the "(.*?)" link$/) do |arg1|
pending # express the regexp above with the code you wish you had
end
然后我将此添加到我的代码中，以便尝试进行测试：
Background:
Given there are the following users:
| email | password | admin |
| user@ticketee.com | password | false |
| admin@ticketee.com | password | true |
And there is a project called "TextMate 2"
然后我运行测试并得到了这个错误：

这就是我有admins_only的show.html.erb：
<% title(@project.name, "Projects") %>
<h2><%= @project.name %></h2>
<% admins_only do %>
<%= link_to "Edit Project", edit_project_path(@project) %>
<%= link_to "Delete Project", @project, :method => :delete, :confirm => "Are you sure you want to delete this project?" %>
<% end %>
<%= link_to "New Ticket", new_project_ticket_path(@project) %>
<ul id= 'tickets'>
<% @project.tickets.each do |ticket| %>
<li>
#<%= ticket.id %> - <%= link_to ticket.title, [@project, ticket] %>
</li>
<% end %>
</ul>

答案 0 :(得分：1)
您尚未在相应的_steps.rb文件中实现步骤定义。 Web Steps提供了一些通用的步骤定义，但它们很糟糕，你不应该使用它们。
要解决此问题，您需要粘贴此内容：
Then(/^I should not see the "(.*?)" link$/) do |arg1|
pending # express the regexp above with the code you wish you had
end
Given(/^I am signed in as "(.*?)"$/) do |arg1|
pending # express the regexp above with the code you wish you had
end
Then(/^I should see the "(.*?)" link$/) do |arg1|
pending # express the regexp above with the code you wish you had
end
进入step_definitions目录内的ruby文件，并用代码替换pending以满足该步骤的条件。
