Configure Ember CLI to use http-mock

The setup:

ember new shop
cd shop
ember install:addon ember-cli-scaffold
ember generate scaffold product name:string available:boolean
ember generate adapter product

I'd like to use http-mock but http://ift.tt/1Osat0p tells me to do this:

ember g http-mock products

After that I use this code to generate two example products:

server/mocks/products.js

module.exports = function(app) {
  var express = require('express');
  var productsRouter = express.Router();

  productsRouter.get('/', function(req, res) {
    res.send({
      'products': [
      {
        id: "1",
        name: 'Orange',
        available: true
       }, {
        id: "2",
        name: 'Apple',
        available: false
        }
      ]
    });
  });

  [...]

When I use the command ember server and browse to http://localhost:4200/products I see nothing.

What am I missing? What else do I have to start or to configure?
