如何在angular单元测试中访问@Input属性

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

@Component({
  template: '<div>{{ inputProperty }}</div>'
})
class TestComponent {
  @Input() inputProperty: string;
}

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

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

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

  it('should access @Input property', () => {
    component.inputProperty = 'Test Input';
    fixture.detectChanges();
    const element = fixture.nativeElement.querySelector('div');
    expect(element.textContent).toBe('Test Input');
  });
});
