Question

请帮我解决这个问题。我已经尝试了很多东西，但没有解决，网上有很多东西，但没有得到解决方案。我的问题是我在组件构造函数中传递了一些类，现在它在krma测试中抛出了错误。

我的组件代码

setTimeout(function(){ insert Facebook pixel code here}, 3000);

我的规格 ----------------

`import { Component, OnInit } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import { Store } from '@ngrx/store';
import { NavbarSandbox } from '../../../navbar/sandbox/navbar.sandbox';
import { ServiceProviderResult } from '../../../shared/models/service-provider';

@Component({
  selector: 'ccw-nav-bar',
  templateUrl: './nav-bar.component.html',
  styleUrls: ['./nav-bar.component.scss']
})
export class NavBarComponent implements OnInit {
  serviceProviderList$: Observable<ServiceProviderResult[]>;
  constructor(public store: Store<any>, public navSandBox: NavbarSandbox) { }

  ngOnInit() {
    this.serviceProviderList$ = this.navSandBox.getServiceProviderListAPI(null);
  }

  changeCurrentServiceProviderChanged(selectedProviderResult: number): void {
    if (selectedProviderResult !== undefined) {
      this.navSandBox.setSelectedServiceProvider({ id: selectedProviderResult });
    }
  }

  // To get selected dropdown value
  getSelectedData(): void {
    this.navSandBox.getSelectedServiceProvider().subscribe((res) => { console.log(res); });
  }

}
