angular - 在 Angular Testing 中注入(inject)位置

Question

我在我的 Angular 组件中使用 Location 注入(inject)来将用户重定向到另一条路线。它按预期工作，但当我运行测试时，我收到此消息

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

这是我的测试类

import { async, ComponentFixture, TestBed } from '@angular/core/testing';

import { CreateGroupComponent } from './create-group.component';
import { CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
import { ReactiveFormsModule } from '@angular/forms';
import { GroupService } from '../core/groupService/group.service';
import { AuthService } from '../core/authService/auth.service';
import { RouterTestingModule } from '@angular/router/testing';

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

  beforeEach(async(() => {

    const mockGroupService: any = {

    };

    const mockAuthService: any = {

    };

    TestBed.configureTestingModule({
      imports: [ReactiveFormsModule],
      declarations: [CreateGroupComponent],
      schemas: [CUSTOM_ELEMENTS_SCHEMA],
      providers: [{ provide: AuthService, useValue: mockAuthService }, { provide: GroupService, useValue: mockGroupService }]
    })
      .compileComponents();
  }));

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

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

我承认，我也在学习 Angular 测试，但是...您不需要将“RouterTestingModule”添加到您的 TestBed 的“imports:[]”数组吗？

imports: [RouterTestingModule, ReactiveFormsModule],
