TestXml

DESCRIPTION:

TestXml is a small extension for testing XML/HTML. Extending RSpec and TestUnit it makes asserting and comparing XML snippets easy, and is especially helpful for testing RESTful web services and their XML representations.

FEATURES:

  • runs with RSpec2, Test::Unit, MiniTest and Cucumber

  • Ruby 1.8 and 1.9

  • test XML structure and content

INSTALL

gem install test_xml

EXAMPLES:

Test::Unit and MiniTest

def test_item_representation
  assert_xml_equal "<item><id>1</id></item>", @item.to_xml
end

RSpec

it "should contain the id" do
  @item.to_xml.should equal_xml(<<-XML)
    <item>
      <id>1</id>
    </item>
  XML
end

Cucumber

Scenario:
  When I post some data
  Then the response should match the following xml
  """
    <transaction>
      <status>success</status>
      <id/>
      <order_id/>
    </transaction>
  """

USAGE:

RSpec

In your spec_helper.rb

require 'test_xml/spec'

And in the actual spec, use these matchers:

  • equal_xml

  • contain_xml

  • equal_xml_structure

  • contain_xml_structure

Test::Unit

In the test_helper.rb

require 'test_xml/test_unit'

In your test file, use these matchers:

  • assert_xml_equal

  • assert_xml_contain

  • assert_xml_structure_equal

  • assert_xml_structure_contain

Negative assertions are available as assert_not_*.

MiniTest

In the test_helper.rb

require 'test_xml/mini_test'

Check the Test::Unit section for available assertions.

Cucumber

In the features/env.rb

require 'test_xml'
require 'test_xml/spec'
World(TestXml::Spec)

In your steps file e.g. features/step_definitions/xml_steps.rb add this step:

Then /^the response should match the following xml$/ do |xml|
  response.body.should equal_xml(xml)
end
