Although using the PEAR Installer is the only supported way to install PHPUnit, you can install PHPUnit manually. For manual installation, do the following:
1.Download a release archive from http://pear.phpunit.de/get/ and extract it to a directory that is listed in the include_path of your php.ini configuration file.
2.Prepare the phpunit script:
a)、Rename the phpunit.php script to phpunit.
b)、Replace the @php_bin@ string in it with the path to your PHP command-line interpreter (usually /usr/bin/php).
c)、Copy it to a directory that is in your path and make it executable (chmod +x phpunit).
3.Prepare the PHPUnit/Util/PHP.php script:
a)、Replace the @php_bin@ string in it with the path to your PHP command-line interpreter (usually /usr/bin/php).
