Angular Unit Test:如果构造函数以Globals.ts文件作为参数，如何创建组件实例

import { ComponentFixture, TestBed } from '@angular/core/testing';
import { MyComponent } from './my.component';
import { Globals } from './Globals';

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

  beforeEach(async () => {
    await TestBed.configureTestingModule({
      declarations: [MyComponent],
      providers: [Globals] // 提供Globals服务的实例
    }).compileComponents();
  });

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

  // 其他测试用例可以在这里定义
});

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

it('should have correct Globals instance', () => {
  expect(component.globals instanceof Globals).toBeTruthy();
});
