How to unit test Routes in ember-cli app using qunit?

Question

I can't seem to get the model hooks and actions triggered from a unit test.

Any sample/blog doing this ember-cli environment would be a great help!

I found this link What kind of unit test solution for the routes in Ember.js?

but route.model() is throwing errors as :transition isn't defined.

import { test, moduleFor } from 'ember-qunit';

moduleFor('route:sample', 'SampleRoute', {
  // Specify the other units that are required for this test.
});

test("beforeModel hook works", function(){
    var route = this.subject();
    Ember.run(function(){
        route.set("model", "Sample data");
    })
    console.log("Model set. Was beforeModel hook called?");
});

The Sample Route

import Ember from 'ember';

export default Ember.Route.extend({

    beforeModel: function (transition) {
        console.log("Inside before-model hook");
    },

    afterModel: function() {
        console.log("In after-model hook");
    }
});

Unfortunately, that's not quite how things work. beforeModel isn't simply called before model is set, and afterModel afterward. They are just hooks that are called in that sequence ( beforeModel -> model -> afterModel ) as part of the lifecycle of a route.

Unfortunately, I haven't found a good way to unit tests Routes. If you have specific beforeModel logic that you need to test, then maybe you can just call beforeModel directly? I have found that Route logic is best tested through acceptance-style tests, since you then have the Route being invoked in the same way it will be when the application is actually running.
