I think making this consistent for testing is a good idea. The fact that
the Mock classes in nifi can replicate the runtime behavior is very important
to implementors.
I think that the changes to the other processors might be better suited
outside of this pr though.
Also, I wouldn't mind seeing a comment or more comments in the Mock class
referencing the runtime behavior they are enforcing.---
