I don't believe so.  The outline is still completely empty.

I think what really needs to happen is that someone knowledgeable in 
testing needs to put together a basic outline.  And the focus should be on 
actionable stuff: some time should be spent describing what a test plan 
is, and then an assignment could be to select a feature from some open 
source project and propose a testing plan.

But fleshing out the outline is the first step, I think.  Please feel free 
to work on the testing chapter outline:
