Aurelia unit test route paths to modules - unit-testing

Question

I've been looking for a good pattern to unit test routes I have configured in my application so that I know the specified modules exist on disk as defined.
Here is an example route configuration:
import { Aurelia, PLATFORM } from 'aurelia-framework';
import { Router, RouterConfiguration } from 'aurelia-router';
export class App {
params = new bindParameters();
router: Router;
configureRouter(config: RouterConfiguration, router: Router) {
config.title = 'Aurelia';
config.map([{
route: ['', 'home'],
name: 'home',
settings: { icon: 'home' },
moduleId: PLATFORM.moduleName('../home/home'),
nav: true,
title: 'Home'
}, {
route: 'sample',
name: 'sample',
settings: { icon: 'education' },
moduleId: PLATFORM.moduleName('../sample/index'),
nav: true,
title: 'Sample Information'
}]);
this.router = router;
}
}
class bindParameters {
user = "user_name";
}
To test it I took the approach of passing in an instance of a router then checking to see if it exists:
import { App } from './app';
import jasmine from 'jasmine';
import { Container } from "aurelia-framework";
import { RouterConfiguration, Router } from "aurelia-router";
describe('application routes', function () {
let app: App;
let router: Router;
let routerConfiguration: RouterConfiguration;
let configureRouter: Promise<void>;
beforeEach(() => {
var container = new Container().makeGlobal();
routerConfiguration = container.get(RouterConfiguration);
router = container.get(Router);
app = new App();
app.configureRouter(routerConfiguration, router);
configureRouter = router.configure(routerConfiguration);
routerConfiguration.exportToRouter(router);
});
it('should exist for sample', function () {
expect(router).not.toBeNull();
//configureRouter.then(function () {
//var route = router.routes.find((route) => route.name == 'sample');
// add some assert that the sample module can be found
// done();
//});
});
});
My current problem is that the container is returning a null Router as shown by the current test. The closest pattern I have found to what I am trying to do is in this question.
What am I missing in my example test and also is there a better way to test route configuration?

It seems #thinkOfaNumber was right. Turns out my test was good, but I was missing reflect-metadata. When I applied the fix outlined in this stackoverflow post my tests passed.
