Laravel unit tests not running on windows

I was trying to do unit testing with laravel framework. I followed all the steps described in laravel documentation but it doesn't work when I do "phpunit" command. Tried the same command on a linux machine, it ran perfectly....

Desktop\space-bubble\phpunit.xml

Time: 0 seconds, Memory: 6.00Mb

No tests executed!
