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 3.8 requires PHP 5.4.7 (or later).
PHP_CodeCoverage, the library that is used by PHPUnit to collect and process code coverage information, depends on Xdebug 2.2.1 (or later).

Installation

There a three supported ways of installing PHPUnit.

You can use the PEAR Installer or Composer to download and install PHPUnit as well as its dependencies. You can also download a PHP Archive (PHAR) of PHPUnit that has all required (as well as some optional) dependencies of PHPUnit bundled in a single file.

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

Composer

To add PHPUnit as a local, per-project dependency to your project, simply add a dependency on phpunit/phpunit to your project's composer.json file. 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.*"
    }
}

PHP Archive (PHAR)

wget http://pear.phpunit.de/get/phpunit.phar
chmod +x phpunit.phar
