Karma/Jasmine unit test with JSPM 404 on my JSPM packages

Question

I am trying to make JSPM / Karma / Babel / Jasmine all work together. But I am getting the error when running karma start

15 04 2016 17:34:02.428:INFO [karma]: Karma v0.13.22 server started at http://localhost:9876/

  });
};

My app.js has these imports:

import { inject } from 'aurelia-dependency-injection';
import { Router } from 'aurelia-router';
import { Navscroll } from '../src/modules/scroll-anim.js'

I am not sure if my proxy is setup right or not or what the problem is?

Error: Error: XHR error (404 Not Found) loading /Users/allen/dev/work/Web/aurelia-dependency-injection.js
Error loading /Users/allen/dev/work/Web/wwwroot/src/app.js

This is your first problem. It's not XHRing to your proxy. Instead it's trying to use a path url. This will definitely fail as an XHR can only do HTTP as far as I have ever seen. You need the protocol://host:port/path format.

Try going to http://localhost:9876/src/app.js and see what shows up in your browser. (Might not need to include /src/ app.js might be served from root.)

You must be loading the app.js file incorrectly somewhere. Please include the places you load app.js .
