PHP_CodeCoverage

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

Requirements

PHP 5.3.3 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 2.1.3 of Xdebug is required but using the latest version is highly recommended.

PHP 7

phpdbg is currently the only source of raw code coverage data supported for PHP 7. Once Xdebug has been updated for PHP 7 it, too, will be supported.

HHVM

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

Installation

To add PHP_CodeCoverage as a local, per-project dependency to your project, simply add a dependency on phpunit/php-code-coverage to your project's composer.json file. Here is a minimal example of a composer.json file that just defines a dependency on PHP_CodeCoverage 2.0:

{
    "require": {
        "phpunit/php-code-coverage": "^2"
    }
}

Using the PHP_CodeCoverage API

```php <?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'); ```
