Angular unit testcases for @ViewChildren QueryList

Question

I am trying to write unit test cases for view children query list, where I am looping to each element ref & taking width of item to check weather it will fit within div or not. So please tell me how to create a mock DOM for Querylist reference. Below is the code, span with reference #listEle is flex items

Test.component.html:

<div #containerRef>
  <span *ngFor="let val of data| slice: 0:linksShown;" #listEle>
    <a href="val.link">{{ val.name }}</a>
  </span>
</div>

Test.component.ts:

import { ElementRef, OnInit, QueryList, ViewChild, ViewChildren } from '@angular/core';

 @Component({
   selector: 'app-test',
   templateUrl: './test.component.html',
   styleUrls: ['./test.component.scss'],
 })
 export class TestComponent implements OnInit {
  @Input() data;
  @ViewChild('containerRef', { read: ElementRef, static: true }) containerRef: 
  ElementRef;
  listRef: QueryList<ElementRef>;
  @ViewChildren('listEle') set listEle(ref: QueryList<ElementRef>) {
       this.listRef = ref;
  }
  linksShown: number;
  constructor() {}

  ngOnInit() {
     let items = 0;
     let count = 0;
     this.listRef.toArray().forEach((ele) => {
       count += ele.nativeElement.clientWidth;
        if (count  < this.containerRef.nativeElement.clientWidth) {
         count++;
        }
     });
     this.linksShown = count;
    }
  }

Test.component.spec.ts:

import { Component, ElementRef, ViewChild, ViewChildren } from '@angular/core';
import { ComponentFixture, fakeAsync, TestBed, tick } from 
'@angular/core/testing';
import { TestComponent } from './host-links.component';

describe('TestComponent', () => {
  let component: TestComponent;
  let fixture: ComponentFixture<TestComponent>;
  const data = [
     { name: 'test1', link: '/test1' },
     { parentName: 'test2', link: '/test2' }
  ]

  beforeEach(async () => {
     await TestBed.configureTestingModule({
     declarations: [TestComponent],
     }).compileComponents();
  });

  beforeEach(() => {
      fixture = TestBed.createComponent(TestComponent);
      component = fixture.componentInstance;
      component.data = data;
      fixture.detectChanges();
  });

  it('should get the linkShown count', () => {
     component.OnInit();
     expect(component.linksShown).toEqual(2);
  });
})
