Take PHPUnit as an example. You can install it using Composer doing this : composer require phpunit/phpunit This will install a phpunit shortcut in vendor/bin directory. This obviously means you can run it. But, you would have to point to the exact location of the phpunit file to run : /home/username/mysite/vendor/bin/phpunit phpunit.xml But, that’s long and uncomfortable. And you would have to install PHPUnit separately for each projects. I’m gonna tell you how to install binaries...
