Angular 7 Test: NullInjectorError: No provider for ActivatedRoute

Hi have some error with testing my App made with Angular 7. I do not have much experience in angular, so I would need your help+

Error: StaticInjectorError(DynamicTestModule)[BeerDetailsComponent -> ActivatedRoute]:
StaticInjectorError(Platform: core)[BeerDetailsComponent -> ActivatedRoute]:
NullInjectorError: No provider for ActivatedRoute!


the testing code is like this:

import { async, ComponentFixture, TestBed, inject } from '@angular/core/testing';
import { BeerDetailsComponent } from './beer-details.component';
import {
HttpClientTestingModule,
HttpTestingController
} from '@angular/common/http/testing';

describe('BeerDetailsComponent', () => {
let component: BeerDetailsComponent;
let fixture: ComponentFixture<BeerDetailsComponent>;

beforeEach(async(() => {
TestBed.configureTestingModule({
imports: [HttpClientTestingModule],
declarations: [ BeerDetailsComponent ]
})
.compileComponents();
}));

beforeEach(() => {
fixture = TestBed.createComponent(BeerDetailsComponent);
component = fixture.componentInstance;
fixture.detectChanges();
});

it('should create',
inject(
[HttpTestingController],
() => {
expect(component).toBeTruthy();
}
)
)
});


I really can't find any solution.
