Angular6中的单元测试输入事件

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 update input property on input event', () => {
    const inputElement = fixture.nativeElement.querySelector('input');
    inputElement.value = 'test value';
    inputElement.dispatchEvent(new Event('input'));
    fixture.detectChanges();
    expect(component.inputProperty).toEqual('test value');
  });
});
