Markup Validation for PHPUnit

This is an extension for PHPUnit that uses online services for markup validation.

Class	Validates	Service
AssertHTML5	HTML5	http://html5.validator.nu/

Installation

1. Install Composer.

2. composer require kevintweber/phpunit-markup-validators
   or add it to your composer.json file.

3. Install PHPUnit.

Note: I have removed PHPUnit as a composer dependency for folks who run PHPUnit globally. To install PHPUnit locally, use: composer require phpunit/phpunit

Usage

Here is an example of a minimal test case that will pass.

<?php

require_once("vendor/autoload.php");

use Kevintweber\PhpunitMarkupValidators\Assert\AssertHtml5;

class HtmlTest extends PHPUnit_Framework_TestCase
{
    public function testHTMLValidation()
    {
        AssertHTML5::isValidMarkup("<div>Whoa</div>", "Optional custom message.");
    }
}

Each assert class has three methods:

1. isValidMarkup(string $markup, string $message = '', Connector $connector = null)
   Passes test if $markup is valid markup.

2. isValidFile(string $pathToFile, string $message = '', Connector $connector = null)
   Passes test if file at $pathToFile has valid markup.

3. isValidUrl(string $URL, string $message = '', Connector $connector = null)
   Passes test if webpage at $URL has valid markup.

In the event that a test fails, first the $message will be displayed, then a detailed error report will be listed.

(The third parameter is for custom connectors, in case you want to extend this library with your own services.)

Note: Each online service requests that API usage does not exceed 1 request per second. I have included a throttle class to limit requests. An easy workaround is to not use the same test class repeatedly, but rather alternate test classes.
