phpcov

phpcov is a command-line frontend for the PHP_CodeCoverage library.

Installation

PHP Archive (PHAR)

The easiest way to obtain phpcov is to download a PHP Archive (PHAR) that has all required dependencies of phpcov bundled in a single file:

$ wget https://phar.phpunit.de/phpcov.phar
$ chmod +x phpcov.phar
$ mv phpcov.phar /usr/local/bin/phpcov

You can also immediately use the PHAR after you have downloaded it, of course:

$ wget https://phar.phpunit.de/phpcov.phar
$ php phpcov.phar

Composer

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

$ composer require --dev phpunit/phpcov

You can then invoke it using the vendor/bin/phpcov executable.

Usage

Patch Coverage

$ git diff HEAD^1 > /tmp/patch.txt

$ phpunit --coverage-php /tmp/coverage.cov

$ phpcov patch-coverage /tmp/coverage.cov              \

                        --path-prefix /path/to/project
