Small library to test your xml with Test::Unit or RSpec

= 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 RSpec 2 or 3, Test::Unit, MiniTest and Cucumber
  • Ruby >= 1.8
  • Test XML structure and content

== INSTALL

gem install test_xml

== EXAMPLES

=== Test::Unit and MiniTest

def test_item_representation assert_xml_equal "1", @item.to_xml end

=== RSpec

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

=== Cucumber

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

== 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

== ASSERTIONS

=== XML is Equal

Elements, attributes and text nodes are all the same

=== XML Contains

The XML contains the given structure. Checks ancestral relationships, elements, attributes and text nodes starting from and including the root node.

For example, given this XML:

Cee Dee

This will fail:

Cee

as +b+ is not the root node. The check must be written as:

Cee

=== XML Structure is Equal

Like XML is equal, but ignores attributes and text nodes

=== XML Structure Contains

Like XML contains, but ignores attributes and text nodes
