在角度单元测试中渲染div块的一种方法

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

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

  beforeEach(async () => {
    await TestBed.configureTestingModule({
      declarations: [ MyComponent ]
    })
    .compileComponents();
  });

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

  it('should render the div block with correct data', () => {
    const divBlock = fixture.nativeElement.querySelector('.div-block');
    expect(divBlock).toBeDefined();
    
    // 这里可以进行更多的断言，例如检查div块的文本内容、样式等
    
  });
});
