如何在TypeScript/Angular中测试文字？

import { TestBed, ComponentFixture } from '@angular/core/testing';
import { By } from '@angular/platform-browser';
import { YourComponent } from './your.component';

describe('YourComponent', () => {
  let component: YourComponent;
  let fixture: ComponentFixture<YourComponent>;
  let element: HTMLElement;

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

  beforeEach(() => {
    fixture = TestBed.createComponent(YourComponent);
    component = fixture.componentInstance;
    element = fixture.debugElement.nativeElement;
  });

  it('should display the correct text', () => {
    component.text = 'Expected Text';
    fixture.detectChanges();
    expect(element.textContent).toEqual('Expected Text');
  });
});
