Create fake routes to test component's link-to - ember.js

Question

I have a component that gets menu items and renders navbar. So now I'm writing integration test, and I want to make sure, that component renders right links and labels. First of all, I added router initialization to make link-to display href prop:
moduleForComponent('main-menu', 'Integration | Component | main menu',
{
integration: true,
setup() {
const router = getOwner(this).lookup('router:main');
router.setupRouter();
}
});
Now I want to create some fake routes to test component, and to be independent from application router's setup. So I try to use map function:
moduleForComponent('main-menu', 'Integration | Component | main menu', {
integration: true,
setup() {
const router = getOwner(this).lookup('router:main');
router.map(function() {
this.route('link1');
this.route('link2');
});
router.setupRouter();
}
});
And I get Promise rejected before "it renders": router.map is not a function. So how should I implement "fake routes" for tests?

Ok, solved the problem. If someone will ever need something similar, here's how I did it:
import { moduleForComponent, test } from 'ember-qunit';
import hbs from 'htmlbars-inline-precompile';
import { getOwner } from '#ember/application';
import CustomRouter from 'app/lib/router';
moduleForComponent('main-menu', 'Integration | Component | main menu', {
integration: true,
setup() {
const application = getOwner(this),
Router = CustomRouter.extend()
;
Router.map(function() {
this.route('link1');
this.route('link2');
});
application.register('router:main', Router.extend());
application.lookup('router:main').setupRouter();
}
});
test('some awesome tests', function(assert) {
const menuItems = [
{url: 'link1', label: 'link1', href: '/link1'},
{url: 'link2', label: 'link2', href: '/link2'},
]
;
this.set('items', menuItems);
this.render(hbs`{{main-menu items=items}}`);
// some cool tests that now can check href attributes of links
// and don't depend on app's router setup
});
