我该如何调试黄瓜测试？

Question

我有:

When /^(?:|I )follow "([^"]*)"(?: within "([^"]*)")?$/ do |link, selector|  
  with_scope(selector) do
   click_link(link)
  end
end

我打电话给:

Background:
  Given I am an existing admin user
  When I follow "CLIENTS"

我的HTML是这样的:

<a class="active" href="/companies"><h2>CLIENTS</h2></a>

我一直收到这个错误:

.F-.F--U-----U

(::) failed steps (::)

no link with title, id or text 'CLIENTS' found (Capybara::ElementNotFound)
(eval):2:in `click_link'
./features/step_definitions/web_steps.rb:54:in `block (2 levels) in <top (required)>'
./features/step_definitions/web_steps.rb:14:in `with_scope'
./features/step_definitions/web_steps.rb:53:in `/^(?:|I )follow "([^"]*)"(?: within "([^"]*)")?$/'
features/client_add.feature:8:in `When I follow "CLIENTS"'

我尝试过以下几点:

When I follow "<h2>CLIENTS</h2>"

甚至尝试了save_and_open_page应该打开浏览器并仍然得到相同的结果:

Given /^I am an existing admin user$/ do
  role_user = FactoryGirl.create(:role_user)
  admin_user = role_user.user
  sign_in(admin_user)
  save_and_open_page
end

有没有办法打印HTML或某种方式来找出我的测试失败的原因？

Answer 1

我最喜欢调试黄瓜步骤的方法就是调用binding.pry.

确保prygem包含在您的gem文件中:development, test,然后将binding.pry调用放在引发错误的行之前.然后,您应该能够反思与环境的ls命令,如果你能找到水豚会话中运行你可以(如果水豚会话存储为一个名为页面变量)page.html和page.text看什么是可见的.

希望有所帮助.
