In the American judicial system, would a minor be asked to testify in the homicide case against their parent?

I’m watching the French film Anatomy of a Fall and I’m struck by the way they cross-examined the son who’s about 10 or so. Not only is he forced to testify pre-trial, witness reenactments of the death of his father, he is also cross-examined at the trial and allowed to witness it with a gardienne-at-litem.

Would this ever happen in an American trial?
