Angular 7测试中的NullInjectorError：没有ActivatedRoute的提供者

typescript
import { ComponentFixture, TestBed } from '@angular/core/testing';
import { ActivatedRoute, Router } from '@angular/router';
import { YourComponent } from './your-component.component';
describe('YourComponent', () => {
  let component: YourComponent;
  let fixture: ComponentFixture;
  beforeEach(() => {
    TestBed.configureTestingModule({
      declarations: [YourComponent],
      providers: [
        {
          provide: ActivatedRoute,
          useValue: {
            snapshot: {
              paramMap: {
                get: () => '1' // Mock the ActivatedRoute snapshot
              }
            }
          }
        },
        // Add other dependencies as needed
      ],
    });
    fixture = TestBed.createComponent(YourComponent);
    component = fixture.componentInstance;
  });
  it('should create', () => {
    expect(component).toBeTruthy();
  });
});
