Testing Vue Global Variables

Hello,

I am going through the Testing Vue series right now and things work great in there with small examples. Now I am trying to apply it to my current application, which has quite a few more moving pieces. I am running into an issue where Mocha can't find a global variable. The reason is that there is a script section at the bottom of my app.blade.php layout file that puts some variables into global memory for the Vue components to use once they get mounted. This code executes on the server using PHP, as any normal Laravel app does. Has anyone else figured out a good way to make this work?
