I once wanted to test a class whose constructor took several parameters, each requiring an instance of a different interface. These instances weren’t easy to create and weren’t relevant to the test. After some experimenting, I found a way to work around the problem.

Ideally, the class is instantiated with the following parameters:

FINAL(cut) = NEW zcl_person(
  head = my_head
  arms = my_arms
  legs = my_legs ).

I have the head but I don’t have the arms nor the legs, and I don’t feel like creating them because I don’t need them for the test. So I can do the following:

You could do this:

DATA my_arms TYPE REF TO zif_arms.
DATA my_legs TYPE REF TO ZIF_legs.
FINAL(cut) = NEW zcl_person(
  head = my_head
  arms = my_arms
  legs = my_legs ).

But there is a nicer and simpler way:

FINAL(cut) = NEW zcl_person(
  head = my_head
  arms = VALUE #( )
  legs = VALUE #( ) ).

This way you can instantiate the class even without having all the parameters. Bear in mind that arms and legs will be INITIAL, so if they are accessed inside, it will obviously crash. But if they aren’t accessed, here’s an easy way to instantiate the class.
