Angular 7 测试:NullInjectorError:ActivatedRoute 没有提供者 [英] Angular 7 Test: NullInjectorError: No provider for ActivatedRoute

问题描述

您好，在测试我使用 Angular 7 制作的应用时出现了一些错误.我在 Angular 方面没有太多经验，所以我需要您的帮助+

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!

测试代码是这样的:

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();
    }
  )
)
});

我真的找不到任何解决方案.

I really can't find any solution.
