如何对Angular @Input的setter和getter进行单元测试

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

@Component({
  selector: 'app-test',
  template: ''
})
class TestComponent {
  private _inputValue: string;

  @Input()
  set inputValue(value: string) {
    this._inputValue = value;
  }

  get inputValue(): string {
    return this._inputValue;
  }
}

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 set and get input value', () => {
    const inputValue = 'test value';
    component.inputValue = inputValue;
    expect(component.inputValue).toEqual(inputValue);
  });
});
