I am writing the simplest component that is using a routeLink:
@Component({
selector: \'memorySnippet\',
templateUrl: \'
For RC4 with new router now use ...
beforeEach(() => addProviders([
APP_ROUTER_PROVIDERS, // must be first
{provide: APP_BASE_HREF, useValue: '/'}, // must be second
{provide: ActivatedRoute, useClass: Mock},
{provide: Router, useClass: Mock}
]));
A github project using this approach is ...
