This is expected behavior. group
has DontCare
, meaning "I don't care about the validation of my children". AllOrNone fails validation, but group passes validation (because DontCare always passes validation). The parser is valid if all its children are.
In this case, you can still manually check the validation of subgroup
, but it won't throw an error, because the ArgumentParser's children all validate.

Thanks for the reply. I interpreted DontCare
differently.
I guess I should have specified AllChildGroups
instead.
