Junit覆盖Objects.notnull

Question

public List<ClassRoomListAdapterModel> getRoomListItems() {
final List<ClassRoomListAdapterModel> classRoomListItemsList = new ArrayList<>();
if (Objects.nonNull (classRoomListItemsList)) {
classRoomListItemsList.addAll
(classRoomListItemsList);
}
return classRoomListItemsList;
}

Stuck with junit coverage to cover if conditions Objects.nonNull

Answer 1

There is no way classRoomListItemsList can be null, since it is created right beforehand. So to me it seems you should remove the dead code path (=> remove the null check).

Also, you do realize all this method does is produce an empty ArrayList?
