I am trying to set up a development environment for Thirty Bees. 
As far as I am aware of, I have succesfully set up Vagrant, Xdebug and PhpStorm ;-) 
But I have not been able to figure out how to install PHPUnit (Do I need it?). 
So I am currently stucked with this error message: 
 
Can someone guide me in the right direction?
