Can anyone help me ?

Answer 1

Please add

import { RouterModule } from '@angular/router';

in app.module.ts and import it in imports -

imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    RouterModule
],

This worked for me.

Answer 2

Here is the solution that worked for me, inspired by gaurav2887 from this page:

import { RouterTestingModule } from '@angular/router/testing';
...    
beforeEach(() => {
        TestBed.configureTestingModule({
            declarations: [ MyComponent ],
            imports: [ RouterTestingModule ]
        });
...

You need to first import Routes & RouterModule

import { Routes, RouterModule } from '@angular/router';

Then import it with root Constant and Export

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})

Then Export all the Components you want to implement routing with.

That set...Hope it will work.
