php-pear is not working after upgrading to Ubuntu 14.04
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.
Open the terminal and type:
wget https://phar.phpunit.de/phpunit.phar # download the PHP Archive (PHAR) file
chmod +x phpunit.phar
sudo mv phpunit.phar /usr/local/bin/phpunit
There are many different versions of phpunit.phar at https://phar.phpunit.de/. If you use the first command, it will select and download the latest version of phpunit.phar.
