Jasmine Rails, src_files not being loaded from subdirectory

Gems:

jasmine 2.6
jasmine-juery-rails 2.0.3
jquery-rails 4.4.0

ruby 2.6.6
rails 5.0.2

This is how my JS folder is organized

> assets/javascripts
  > 0_global
    > utility.js
    > ...
  > 2_place_order
    > cart.js
    > item.js
    > ...
  > 0_global.js
  > 2_place_order.js

Where the top level .js files in the assets/javascripts folder require the corresponding directory. I.e.,

0_global.js

    //= require_directory ./0_global

2_place_order.js

    //= require_directory ./2_place_order

I'm having trouble getting this set up to work with my jasmine. So in jasmine.yml I required the top level js file, figuring that since that file already requires the directory, it should load, but it does not. I.e., the below doesn't work:

src_files:
  - assets/0_global.js
  - assets/2_place_order.js

Is there a different way to get this to work? I have also tried:

src_files:
  - assets/0_global/*.js
  - assets/2_place_order/*.js

To require the directory from the set up jasmine.yml but this didn't work either. Would like to try to not have to enumerate every js file in the subdirectories.

Thanks!
