I cannot agree with this assumption. Since the policy should not be
touched for the existing components, the test should prove that the
policy object instances are the same, other behavior is an error.

And how is it useful? The toString() method is not implemented for the
printed objects, so the printouts are not readable. I found this print
out as excessive. If it invites to compare the memory addresses, that
has no sense, because it is automatically executed at the end of the
test and the same printout is produced in case of error.

In this case, please, provide a link to the test which covers the

That is what I asked. For what purpose this dummy content is added? Can
you clarify that?
