Note that the action “test” is only on the top level process. Reason is that in fact it is only one process modeled on several pages.
Test
Note that actions “Start” and “Release” are only for main top level process.
We can't event test lower level of isolated process because embedded process can refer directly to data objects of the owner so we need process instances of all owners!
Release – all 3 processes behave as one process. It means that when you make changes in any parts then all get new a version. Top level process and their embedded parts have ALWAYS the same version
