首先它基于 Rails 3 on Action 所以，我将输入我尝试过的每件事以及我遇到的错误，以便任何人都可以帮助我，如果有任何重要的文件我应该添加到我的问题中，请告诉......也许还有标题这个问题不够好，但我不知道我应该给黄瓜问题取什么标题。

在书中，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。

对于身份验证，他使用的是设计 1.4.3 和黄瓜版本 1.0.6，我在第 7 章，特别是在 7.3.3 上。

现在书中的步骤说我们将编写一个黄瓜测试来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"
  When I follow "TextMate 2"
  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时，我遇到了一个关于缺少功能的问题（虽然在书中测试通过了，然后应该被推送到 github，但对我来说它没有通过）所以我在我的代码顶部添加了这个：

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，出现此错误：

➜  ticketee git:(master) ✗ bin/cucumber features/hidden_links.feature
Rack::File headers parameter replaces cache_control after Rack 1.5.

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，以尝试使我的测试通过：

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这个错误：

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

那就是我只有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>

这就是我尝试过但未能解决我的问题的方法，因此感谢您的帮助...

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，您不应该使用它们。

要解决此问题，您需要粘贴以下内容：

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

到 step_definitions 目录中的 ruby​​ 文件中，并将pending替换为满足该步骤条件的代码。
