That does help a little Michael.
I'm basically checking two things in my test method, of which I only posted
a snippet. I want to [1] make sure that the object returned by the
RendererFactoryTool isn't null, and that [2] it is an instance of the
LayerRenderer class.
I appreciate the tip on the use of the instanceof operator. That will make
my code a little cleaner.

Hi,
Maybe I don't see what you want to do (I just woke up), but it seems
that your comment doesn't match your test.
If testResult is an instance of LayerRenderer, so the renderer returned
IS an instance of LayerRenderer !
One more detail : "instance of" is a kind of boolean operator, you can
just write : if (c instanceof LayerManager)
No need to add == true
Hope that helps
