假設(shè)我有一個(gè)在單擊時(shí)發(fā)出事件的組件，即    @Component({      selector: 'component-checkout-payment',      template: `<button (click)="click()>Click me</button>`    })    export class TestComponent{      @Output() clicked = new EventEmitter<boolean>();      click() {        this.clicked.emit(true);      }    }然后我會(huì)像下面那樣分別測(cè)試事件和組件方法嗎？it('should emit an event when `click` is called`, () => {  jest.spyOn(component.clicked, 'emit');  component.click();  expect(component.clicked.emit).toHaveBeenCalledWith(true);});it('should call `click` when button has been clicked`, () => {  jest.spyOn(component, 'click');  let button = fixture.debugElement.nativeElement.querySelector('button');  button.click();  expect(component.click).toHaveBeenCalled();})或者我會(huì)測(cè)試當(dāng)按鈕被點(diǎn)擊時(shí)，它又會(huì)發(fā)出一個(gè)事件嗎？it('should emit event when button has been clicked`, () => {  jest.spyOn(component.clicked, 'emit');  let button = fixture.debugElement.nativeElement.querySelector('button');  button.click();  expect(component.clicked.emit).toHaveBeenCalledWith(true)})我假設(shè)是后者，因?yàn)樗鼘⑶皟蓚€(gè)測(cè)試合二為一。不過(guò)我想澄清一下。我還想知道這些類(lèi)型的測(cè)試是單元測(cè)試、集成測(cè)試還是 e2e 測(cè)試。
