PHP_CodeCoverage

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

Requirements

PHP 5.6 is required but using the latest version of PHP is highly recommended.

PHP 5

Xdebug is the only source of raw code coverage data supported for PHP 5. Version 2.2.1 of Xdebug is required but using the latest version is highly recommended.

PHP 7

Version 2.4.0 (or later) of Xdebug as well as phpdbg are supported sources of raw code coverage data for PHP 7.

HHVM

A version of HHVM that implements the Xdebug API for code coverage (xdebug_*_code_coverage()) is required.

Installation

You can add this library as a local, per-project dependency to your project using Composer:

composer require phpunit/php-code-coverage

If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:

composer require --dev phpunit/php-code-coverage

Using the PHP_CodeCoverage API

<?php
$coverage = new \SebastianBergmann\CodeCoverage\CodeCoverage;
$coverage->start('<name of test>');

// ...

$coverage->stop();

$writer = new \SebastianBergmann\CodeCoverage\Report\Clover;
$writer->process($coverage, '/tmp/clover.xml');

$writer = new \SebastianBergmann\CodeCoverage\Report\Html\Facade;
$writer->process($coverage, '/tmp/code-coverage-report');
