I have PHPStorm 8.0.1.
PHPUnit is installed via PHAR archive like:
wget https://phar.phpunit.de/phpunit.phar
chmod +x phpunit.phar
sudo mv phpunit.phar /
In order to have PHAR archive indexed by IDE it has to have .phar
extension (that's a requirement).
The easiest solution is to place phpunit.phar
somewhere in your project (usually it would be PROJECT_ROOT/vendor/
folder).
If having local copy is not desired (for whatever reason; although composer and other similar kind of tools (bower/npm/etc) are primarily aimed at keeping dependency stuff/packages locally), you may use symbolic links: either create a symbolic link to that file locally (e.g. PROJECT_ROOT/phpunit.phar
--> /usr/bin/phpunit
) .. or place a full copy (or such symbolic link) in separate folder somewhere on your disk and then reference it via PhpStorm's Settings | PHP | Include Paths
functionality.
