Unit tests not working with vagrant

Hello,

I’m developing a plugin for shopware, and i want to use unit tests.

I’m developing on Windows, so thats why I’m using vagrant to host the site.

Now I want to run unit tests, but every time I get this error:

Shopware Kernel not booted
 /home/vagrant/www/shopware/engine/Shopware/Application.php:405
 /home/vagrant/www/shopware/engine/Shopware/Components/Test/Plugin/TestCase.php:65

My vagrant website is running and working fine. Im using the unit test example plugin.

Any advice?
