A work in progress, drop-in replacement for the following deprecated PHPUnit assertions:

• assertSelectCount()
• assertSelectRegExp()
• assertSelectEquals()
• assertTag() (not yet ported)
• assertNotTag() (not yet ported)

• Port assertTag() and assertNotTag().
• Improve tests.
• Improve error messages.
• Improve comments and documentation.
• Add XPath support.

The PHPUnit DOM assertions require PHP 7.0 or later.

The recommended way to install the PHPUnit DOM assertions is through composer. Just create a composer.json file and run the php composer.phar install command to install it:

{
    "require-dev": {
        "phpunit/phpunit-dom-assertions": "~2"
    }
}

Extend PHPUnit\Framework\DOMTestCase to use the DOM assertions:

namespace My\Tests;

use PHPUnit\Framework\DOMTestCase;

class DOMTest extends DOMTestCase
{
    public function testSelectEquals()
    {
        $html = file_get_contents('test.html');
        $selector = 'span.test_class';
        $content  = 'Test Class Text';

        $this->assertSelectEquals($selector, $content, true, $html);
    }
}

To run the test suite, you need composer.

$ php composer.phar install
$ vendor/bin/phpunit
