karma.js not returning any results following basic "karma init" setup

I'm following the "Introduction to Karma" tutorial by egghead.io found here http://ift.tt/1m3cFPa , and followed the following (on Windows):

> npm install --g karma-cli
> npm install karma karma-jasmine karma-chrome-launcher --save-dev
karma init

Followed default configuration on initial karma configuration, and then created a test.spec.js file in current folder with the following code:

describe('Test', function() {
    it('It should be true', function() { expect(true).toBe(true); });
});

Lastly, I added such file to the karma.conf.js file like so:

files: [
      'test.spec.js'
    ],

However, upon running

karma start karma.conf.js

I get nothing but a:

25 11 2015 16:35:35.551:INFO [karma]: Karma v0.13.15 server started at http://localhost:9876/

Why don't any tests execute? Also, opening that localhost url (it's the same as setting browsers to ['chrome'] in karma.conf.js) just shows that karma is running and that chrome is idle, but no test results are returned.

edit: Added karma.conf.js
