'Class constructor FormControl cannot be invoked without 'new'
I have a simple Angular 13 repo where @ng-stack/forms is used like
import { Component } from '@angular/core';
import { FormControl } from '@ng-stack/forms';
@Component({
selector: 'app-root',
})
export class AppComponent {
control = new FormControl<string>('');
}
When I run Jest test I got an error:
> [email protected] test
> jest --no-cache
FAIL src/app/app.component.spec.ts
AppComponent
× should create the app (54 ms)
● AppComponent › should create the app
TypeError: Class constructor FormControl cannot be invoked without 'new'
7 | })
8 | export class AppComponent {
> 9 | control = new FormControl<string>('');
