ruby-on-rails – 如何使用多行字符串示例比较Cucumber步骤中的x

Scenario: Retrieve a customer via my reference id (as an integer or simple string)
Given I have a customer with these attributes
  | reference | first_name | last_name | email           |
  | 7890      | Joe        | Blow      | joe@example.com |
When I send a GET request to https://[@subdomain].chargify.com/customers/lookup.xml?reference=7890
Then the response status should be "200 OK"
And the response should be the xml:
  """
  <?xml version="1.0" encoding="UTF-8"?>
  <customer>
    <id type="integer">`auto generated`</id>
    <first_name>Joe</first_name>
    <last_name>Blow</last_name>
    <email>joe@example.com</email>
    <organization>`your value`</organization>
    <reference>7890</reference>
    <created_at type="datetime">`auto generated`</created_at>
    <updated_at type="datetime">`auto generated`</updated_at>
  </customer>
  """

我正在尝试按照他们的方法测试我们在这里开发的API,而不是逐个检查标签,就像我在遇到这个例子之前所做的那样.

到目前为止,由于格式问题,没有运气将响应的输出与步骤的多行字符串相匹配.没有找到与Nokogiri的方法,也没有简单的剥离字符串比较.

是否有一种优雅(高效)的方式来做到这一点？

这是使用Mark解决方案的黄瓜步骤：

Then /^I should see the following output$/ do |xml_output|
  response = Hash.from_xml(page.body)
  expected = Hash.from_xml(xml_output)  
  expected.diff(response).should == {}
end
