shulard/atoum-xml-extension Build Status Latest Stable Version

This atoum extension allows you to test XML document using atoum. It's possible to execute xpath against the document or to validate it using DTD, XSD or RelaxNG schema. You can use it to validate HTML documents too.

Example

<?php
namespace shulard\example\xml;

use atoum;

class foo extends atoum\test
{
    public function testXMLDocument()
    {
        $xml = <<<XML
<?xml version="1.0" ?>
<root xmlns:atom="http://purl.org/atom/ns#" xmlns:dc="http://purl.org/dc/elements/1.1/">
    <atom:feed>1<dc:node>namespaced content</dc:node>2</atom:feed>
    <node attribute="value" />
    <node m:attribute="namespaced value" />
</root>
XML;

        $this
            ->then
                ->xml($xml)
                    ->isValidAgainstSchema
                        ->dtd('file://path/to.dtd', 'root')
                ->node
                    ->hasNamespace('atom', 'http://purl.org/atom/ns#')
                    ->isUsedNamespace('dc', 'http://purl.org/dc/elements/1.1/')
                    ->withNamespace('m', 'http://purl.org/atom/ns#')
                        ->xpath('//m:feed')
                            ->hasSize(1)
        ;
    }
}

When running this test, the XML document will be loaded and:

  • Validate the document using a DTD;
  • Check if atom namespace is present in document declaration;
  • Check that dc namespace is used inside the document;
  • Execute a xpath one namespaced node and check returning node collection.

Install it

Install extension using composer:

composer require --dev shulard/atoum-xml-extension

Enable and configure the extension using atoum configuration file:

<?php

// .atoum.php

require_once __DIR__ . DIRECTORY_SEPARATOR . 'vendor' . DIRECTORY_SEPARATOR . 'autoload.php';

use mageekguy\atoum\xml;

$runner->addExtension(new xml\extension($script));

Use it

<?php
namespace shulard\example\xml;
