How to import Routes in the Spec - angular6

Question

I have the following route defined in app-routes.ts as a separate module
import {NgModule} from '#angular/core';
import {RouterModule, Routes} from "#angular/router";
import {AppComponent} from "./app.component";
...
const routes:Routes = [
{
path: 'new',
component: New
canActivate:[AuthGuard]
},
{
path:'list',
component:List
},
{
path: 'signup',
component: SignupComponentComponent
},
{
path: '',
redirectTo: 'home',
pathMatch:'full'
},
{
path: 'home',
component:HomepageContentComponentComponent
},
{ path: '**',
component: PageNotFoundComponent }
];
#NgModule({
imports:[RouterModule.forRoot(routes)], //
exports: [RouterModule],
providers:[]
})
export class AppRoutingModule{}
I am using the route in the HomePageComponent. How do I test the routing? I know I need to use RouterTestingModule. like follows:
beforeEach(async(() => {
TestBed.configureTestingModule({
imports:[RouterTestingModule.withRoutes(routes)], //routes is undefined here
declarations: [ HomepageContentComponentComponent,
]
})
.compileComponents();
}));
But the routes variable defined as const routes:Routes = ... in AppRoutingModule isn't available here.
Question 1) How in my current setup, I can make routes visible in the specs
Question 2)I thought to create a separate file myroutes.ts which contains only the routes array so that I can use it in the specs but even that doesn't work. Why? ( something like the following)
my-route.ts
const routes:Routes = [
{... ];
Why am I note able to use routes in imports:[RouterTestingModule.withRoutes(routes)] when I created it in a sepafrate file?

Answer 1

I should have exported the routes as export const routes:Routes
