Eric Secules updated NIFI-10583:
--------------------------------
Description:
When writing some custom processors I noticed that I can execute the following
code in onTrigger which would set the attribute when I run in
StandardProcessSession on a real nifi, but would fail my unit tests if I assert
that the attribute exists.
{code:java}
FlowFile ff = session.get();
session.putAttribute(ff, "foo", "123");
session.transfer.(ff, REL_SUCCESS)
{code}
So the StandardProcessSession mutates the flowfile passed in while the
MockProcessSession does not.
