i am getting following error when running a unit test using karma and jasmine

Error:
Failed: Template parse errors:
'router-outlet' is not a known element:

1. If 'router-outlet' is an Angular component, then verify that it is part of this module.
2. If 'router-outlet' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("

Add

import { RouterTestingModule } from '@angular/router/testing';

and then

describe('AppComponent', () => {
  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [
        AppComponent
      ],
      imports: [
        RouterTestingModule
      ]
....

ok..
at the top of your xxx.spec.ts file. Add import { RouterTestingModule } from '@angular/router/testing';

Then in the section

  TestBed.configureTestingModule({
      declarations: [
        AppComponent
      ],
      imports: [    //  <------ add the imports Array with the RouterTesting Module
        RouterTestingModule
      ]

The RouterTestingModule is automatically added to app.component.spec.ts when you create an application with routing

Hello,

Here is the Quick and Simple Solution if anyone is getting the error:

" 'router-outlet' is not a known element " in angular project,

then,

Just go to the " app.module.ts " file & add the following Line:

" import { AppRoutingModule } from './app-routing.module'; "

and also ' AppRoutingModule ' in imports.

Thank you!!
