在单元测试中单击Angular2触发器按钮并验证事件处理

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 handle button click event', () => {
    spyOn(component, 'handleClick');
    const button = fixture.nativeElement.querySelector('button');
    button.click();
    fixture.detectChanges();
    expect(component.handleClick).toHaveBeenCalled();
    // Add more assertions to test the expected behavior
  });
});
