tns : 7.0.6

Describe the bug
We are facing issue in integrating unit testing in our codebase. We have followed steps mentioned in the documentation for integrating the unit test framework.
Ref Doc : https://docs.nativescript.org/development-workflow.html#angular-testbed-integration
Imports mentioned in the docs are not compatible with ns7. It keeps giving error.

We have tried updating the imports

from :
import 'nativescript-angular/zone-js/testing.jasmine'
import { nsTestBedInit } from 'nativescript-angular/testing'
nsTestBedInit()

to :

import '@nativescript/zone-js/testing.jasmine'
import { nsTestBedInit } from '@nativescript/angular/testing'
nsTestBedInit()

Its giving error :
