通过spyOn进行角测试停止传播

问题描述 投票:0回答:1

我尝试测试我的stopPropagation行为。当我在浏览器中对其进行测试时,该控制台将仅打印“按钮”和“之间”。

当我在测试中尝试spyOn时,它不起作用。它说该方法被调用了。

这里是一个非常简单的例子。

角组件:

 @Component({
  selector: 'app-prevent-event',
  templateUrl: './prevent-event.component.html',
  styleUrls: ['./prevent-event.component.scss']
})
export class PreventEventComponent implements OnInit {

  constructor() { }

  ngOnInit() {
  }

  clickDiv() {
    console.log("div");
  }

  clickButton() {
    console.log("button");
  }

  clickDivBetween(event) {
    event.stopPropagation();
    console.log("between");
  }
}

HMTL:

<div (click)="clickDiv()">
  <div (click)="clickDivBetween($event)">
    <button id="btn1" (click)="clickButton()">Test</button>
  </div>
</div>

测试:

 it('should prevent the div click', () => {
    const spy1 = spyOn(component, "clickButton");
    const spy2 = spyOn(component, "clickDivBetween");
    const spy3 = spyOn(component, "clickDiv");
    fixture.debugElement.query(By.css("#btn1")).nativeElement.click();
    expect(spy1).toHaveBeenCalled();
    expect(spy2).toHaveBeenCalled();
    expect(spy3).not.toHaveBeenCalled();
  });

您的测试应该是:-

it('should prevent the div click', () => {
    const spy1 = spyOn(component, "clickButton");
    const spy3 = spyOn(component, "clickDiv");
    fixture.debugElement.query(By.css("#btn1")).nativeElement.click();
    expect(spy3).not.toHaveBeenCalled();
});
