Current behavior

triggerEventHandler requires three arguments, which seems to imply that it doesn't work with void event emitters?

Expected behavior

I though I should be able to do spectator.triggerEventHandler(MyComponent, 'myEventEmitter')

Minimal reproduction of the problem with instructions

For bug reports please provide the STEPS TO REPRODUCE and if possible a MINIMAL DEMO of the problem via
https://stackblitz.com or similar (you can use this template as a starting point: https://bit.ly/2zme3bj).

@Component({
    selector: 'app-child',
    template: ''
})
class ChildComponent {
    @Output() linkChanged = new EventEmitter<void>()
}

@Component({
    selector: 'x',
    template: '<app-child (linkChanged)="changed()"></app-child>'
})
class FooComponent {
    changed(): void {}
}

describe('FooComponent', () => {
    it('should emit', () => {
        const createComponent = createComponentFactory(FooComponent)
        const spectator = createComponent()
        spectator.triggerEventHandler(ChildComponent, 'linkChanged')
    })
})

@NetanelBasal That's not the same thing. You're showing how to verify the child component emits the event, which I've done in the child's tests. I'm trying to verify that this component has hooked up the child's emitted event to a specific method in this component.
