馃悶 bug report

Affected Package

The issue is caused by package angular/core

Is this a regression?

Yes, the previous version in which this bug was not present was: 9.0.0-rc.1 without ivy.


In unit test i have <input type="radio" /> and want to get some property (in my case, it's "checked") by Without ivy this code works fine:

The component:

  selector: 'app-root',
  template: `<input type="radio" value="one" [(ngModel)]="active"/>`
export class AppComponent {
  active = 'one';

The unit test:

it('issue example', () => {
    console.log('debugElement properties', debugElement.query(By.css('input[type="radio"]')).properties);
    console.log('debugElement properties checked', debugElement.query(By.css('input[type="radio"]')).properties.checked);
    console.log('nativeElement checked', debugElement.query(By.css('input[type="radio"]')).nativeElement.checked);

If ivy enable, same code will be work differently.

Hmmmmm, I don't see the FormsModule being imported in your test (I guess the checked property is set by ngModel). I find it surprising that it used to with VE...

FormsModule imported into AppModule, which imported in my test.
