PHPUnit

PHPUnit is the de-facto standard for unit testing in PHP projects. It provides both a framework that makes the writing of tests easy as well as the functionality to easily run the tests and analyse their results.

Requirements

• PHPUnit 3.7 requires PHP 5.3.3 (or later) but PHP 5.4.6 (or later) is highly recommended.
• PHP_CodeCoverage, the library that is used by PHPUnit to collect and process code coverage information, depends on Xdebug 2.0.5 (or later) but Xdebug 2.2.1 (or later) is highly recommended.

Installation

PHP Archive (PHAR)

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

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

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

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

Composer

Simply add a dependency on phpunit/phpunit to your project's composer.json file if you use Composer to manage the dependencies of your project. Here is a minimal example of a composer.json file that just defines a development-time dependency on PHPUnit 3.7:

{
    "require-dev": {
        "phpunit/phpunit": "3.7.*"
    }
}

For a system-wide installation via Composer, you can run:

composer global require 'phpunit/phpunit=3.7.*'

Make sure you have ~/.composer/vendor/bin/ in your path.

PEAR Installer

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

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