Angular 18 template: Module '"@angular/core/testing"' has no exported member 'async'

[RDB-DA]

async was removed in Angular 12
The spec of counter component i.e. "counter.component.spec.ts"

import { async, ComponentFixture, TestBed } from '@angular/core/testing';

To Reproduce
Module '"@angular/core/testing"' has no exported member 'async'.
Check screenshot

Expected behavior
async was deprecated because it conflicted with the JavaScript async keyword.
waitForAsync does the same thing: it wraps an asynchronous test function and ensures Angular waits for async tasks
