如何在Jasmine中模拟@Input变量？

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

@Component({
  selector: 'app-test',
  template: '<div>{{ inputData }}</div>'
})
export class TestComponent {
  @Input() inputData: string;
}

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

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

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

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

  it('should display the input data', () => {
    const inputData = 'Test Input';
    component.inputData = inputData;
    fixture.detectChanges();

    const element = fixture.nativeElement.querySelector('div');
    expect(element.textContent).toBe(inputData);
  });
});
