PHP_CodeCoverage

PHP_CodeCoverage is a library that provides collection, processing, and rendering functionality for PHP code coverage information.

Requirements

• PHP_CodeCoverage 1.2 requires PHP 5.3.3 (or later) but PHP 5.4.7 (or later) is highly recommended.
• Xdebug 2.0.5 (or later) is required but Xdebug 2.2.1 (or later) is highly recommended.

Installation

PHP_CodeCoverage should be installed using the PEAR Installer, the backbone of the PHP Extension and Application Repository that provides a distribution system for PHP packages.

Depending on your OS distribution and/or your PHP environment, you may need to install PEAR or update your existing PEAR installation before you can proceed with the following instructions. sudo pear upgrade PEAR usually suffices to upgrade an existing PEAR installation. The PEAR Manual explains how to perform a fresh installation of PEAR.

The following two commands (which you may have to run as root) are all that is required to install PHP_CodeCoverage using the PEAR Installer:

pear config-set auto_discover 1
pear install pear.phpunit.de/PHP_CodeCoverage

After the installation you can find the PHP_CodeCoverage source files inside your local PEAR directory; the path is usually /usr/lib/php/PHP/CodeCoverage.

Using the PHP_CodeCoverage API

<?php
require 'PHP/CodeCoverage/Autoload.php';

$coverage = new PHP_CodeCoverage;
$coverage->start('<name of test>');

// ...

$coverage->stop();

$writer = new PHP_CodeCoverage_Report_Clover;
$writer->process($coverage, '/tmp/clover.xml');

$writer = new PHP_CodeCoverage_Report_HTML;
$writer->process($coverage, '/tmp/code-coverage-report');
