Jasmine 列表实例化时出错！（ItemSlideing->；列表），使用TestComponentBuilder对ionic2组件进行单元测试

我对ionic2组件的单元测试有问题。我已在下面附上我的组件、测试和错误

组件

import {Component,Input} from 'angular2/core'
import {IONIC_DIRECTIVES} from 'ionic-angular'

@Component({
    selector: 'my-item',
 // template: `<ion-item>{{name}}</ion-item>`, //<ion-item> is working 
    template: `<ion-item-sliding>{{name}}</ion-item-sliding>`, //<ion-item-sliding> is not working and throws the error;
    directives:[IONIC_DIRECTIVES]  
    })

export class MyIonic2Component {

     public name:string;

}

这是我在模板包含

时遇到的错误，但我没有在其他离子组件中遇到任何错误

来自离子文档
要使用滑动项，请在列表中添加
组件。接下来，在滑动项内部添加一个组件以包含按钮

请将滑动项包装在列表中

template: `<ion-list><ion-item-sliding>{{name}}</ion-item-sliding></ion-list>`

模板：`{{name}`

您的模板结构应该如下所示

<ion-list>
  <ion-item-sliding>
    <ion-item>
    </ion-item>
    <ion-item-options>
    </ion-item-options>
  </ion-item-sliding>
</ion-list>



template: `<ion-list><ion-item-sliding>{{name}}</ion-item-sliding></ion-list>`

<ion-list>
  <ion-item-sliding>
    <ion-item>
    </ion-item>
    <ion-item-options>
    </ion-item-options>
  </ion-item-sliding>
</ion-list>
