= Test::Unit::XML
== An XML Test Framework

Version: 0.1.6

Author: Henrik Mårtensson

(c) 2006 by Henrik Mårtensson

== Introduction

Test::Unit::XML extends the Test::Unit framework with
an assertion for testing well-formed XML documents.

Using Test::Unit::XML is easy. All you have to do is to
require +testunitxml+, and you will then have an
+assert_xml_equal+ assertion available in the
Test::Unit::TestCase class.

In addition to the API documentation included in the package, you can get information about how
to use Test::Unit::XML from the following sources:

* The online tutorial[http://kallokain.blogspot.com/2006/01/testunitxml-quick-start-tutorial.html] at
  the Kallokain[http://kallokain.blogspot.com/] blog.
* The {test cases}[link:../../test/] included in the distribution package.

== Installation

=== Install Using the +RubyGem+ Package Manager

The easiest way to install Test::Unit::XML is to make a remote installation via the RubyGem
package manager:

<tt>gem install testunitxml</tt>

If you have downloaded a gem package from Rubyforge, you can do a local installation:

<tt>cd <em>download_directory_path</em></tt>

<tt>gem install testunitxml -l</tt>

=== Install from a Zip file or Tarball

If you do not have RubyGem installed, you can download a Zip file or tarball and install
from it instead:

1::  Unpack the Zip or tarball archive.
2::  cd to the directory you just unpacked.
3::  Run the command:
     <tt>ruby setup.rb install</tt>



== What Does _Equal_ XML Documents Mean?

It is hard to define exactly what _equal_ means in the
context of XML documents. I have tried to follow W3C
XML recommendations as far as possible. There are a
few things worthy of note:

* Namespace _declarations_, i.e. attributes that declare
  namespaces, are ignored for comparison purposes. (The
  namespaces _are_ used in comparisons.) The reason is
  that XML processors may move the declarations from one
  element to another, or change prefixes in ways that
  cannot be directly controlled by a programmer. For
  example, two different XSLT processors could use
  the same stylesheet and produce XML documents that use
  different namespace prefixes, and have declarations
  on different elements, but are still considered equal.

* Text nodes that are empty or contain only whitespace
  are ignored for comparison purposes. This makes it
  easier to test output from various transformation
  engines. These often produce extraneous whitespace.

== The Future

There are a few things in the pipeline:

* assert_xml_equal_structure - checks that the structure
  of two documents are equal, but ignores content, attributes,
  processing istructions, comments, CDATA, and doctype
  declarations.
* assert_xml_similar - Like assert_xml_equal, but ignores the
  order of child elements.
* Configurability. It _might_ be useful to be able to set
  configuration options for testing. I'll have to think a
  bit about this though.
* Document difference functions, like the Java XMLUnit test
  suite.

I plan to implement these features as I need them in other
projects, so there is no time plan, and no guarantee as to the
order in which I'll implement anything.

== Contact

You can email bug reports, opinions and questions to
mailto:self@henrikmartensson.org. You may also wish to visit
my home page, www.henrikmartensson.org, for more information
about Test::Unit::XML and other projects. I will write about
Test::Unit::XML at the the Kallokain[http://kallokain.blogspot.com/]
blog. You are welcome to visit, and comment.

If you find Test::Unit::XML useful, please do tell me about it. I would like
to list projects that use it on the {Test::Unit::XML web site}[http://testunitxml.rubyforge.org/].

If you find Test::Unit::XML lacking in some respect, or buggy,
I am even more interested. I can't fix bugs I do not know about.

Finally, if you write about Test::Unit::XML, I'd like to link to
the article on my web site, or at least mention it if you write
for a magazine, so please tell me.

== Ruby 1.9.1

To use this gem with Ruby 1.9.1, you'll need to require the
'test-unit' gem to fix some issue with the unit test libraries
shipping with Ruby 1.9.1.

Just add: gem 'test-unit'

== Addendum 13th April 2010 - Merul Patel

This github repository has just been created and the gem needs
to be repackaged so that the tests run
Something went wrong with that request. Please try again.
