Chapter 4. Installing PHPUnit

PHPUnit^[1] is available from the PHP Extension and Application Repository (PEAR), ^[2] which is a framework and distribution system for reusable PHP components. It can be installed using the PEAR Installer:

Due to PEAR's version-naming standard, the PHPUnit package for PHP 5 is called PHPUnit2. PHPUnit is the name of the PHPUnit package for PHP 4 that is the topic of "PHPUnit for PHP 4," later in this book.

After the installation, you can find the PHPUnit source files inside your local PEAR directory; the path is usually /usr/lib/ php/PHPUnit2.

Although using the PEAR installer is the only supported way to install PHPUnit, you can install PHPUnit manually. For manual installation, do the following:

Download a release archive from http://pear.php.net/package/PHPUnit2/download and extract it to a directory that is listed in the include_path of your php.ini configuration file.
Prepare the phpunit script:
1. Rename the pear-phpunit script to phpunit.
2. Replace the @php_bin@ string in it with the path to your PHP command-line interpreter (usually /usr/bin/ php).
3. Copy it to a directory that is in your PATH and make it executable (chmod +x phpunit).
Replace the @package_version@ string in the PHPUnit2/ Runner/Version.php script with the version number of the PHPUnit release you are installing (2.3.0, for instance).
