Test Angular Input

I want an Angular test that mocks keydown of keys 1 and 2 and then assert that the value of the input is 12

My html:

<input
  id="myInput"
/>

My test:

fit('should update input value on key press', () => {
    const inputDebugElement = fixture.debugElement.query(
      By.css('#money-input')
    );
    const inputElement = inputDebugElement.nativeElement as HTMLInputElement;

    inputElement.value = '';
    inputElement.dispatchEvent(new Event('input'));

    const event1 = new KeyboardEvent('keydown', { key: '1' });
    const event2 = new KeyboardEvent('keydown', { key: '2' });

    inputElement.dispatchEvent(event1);
    inputElement.dispatchEvent(event2);

    fixture.detectChanges();

    expect(inputElement.value).toBe('12');
  });

The current result of my test:
