Testing the whole game

In the documentation there is an example of how to set tests per module where you import a player from the current module like this:

import player from '../player';

@RpgModule<RpgServer>({
    player
})
class RpgServerModule { }

but for example, I have a separate module (plugin) for inventory and a separate module for upgrading items and I would like to test them both.

Is it possible to set up tests for multiple modules or for the whole game?
