[Melbourne-pm] Testing: stub modules and Test::More.

G'day. I seem to be having a foolish day, and despite my best efforts I
can't work out how to get past a stumbling block in putting together an
automated test suite.
I have a module that is part of a large, heavy-weight and third party
product, so I want to test it independent of the main system.
It actually has very few dependencies on the real system, just two
functions in a single module, so I figured: easy! Just stub out that
module in my test script and it will "just work."
Unfortunately I can't seem to make that work.
The existing module uses a bit of common third party infrastructure:
use Product::Toolkit::General qw/string log/;
Now, even with a test script that reads (roughly):
use Test::More plan => 27;
... stub version of the module here ...
I get the error:
'Can't locate Product/Toolkit/General.pm in @INC'
I tried every darn thing I could think of, including the
Test::MockModule package, delaying the 'use' of my module until later --
even in a string eval statement -- and so forth.
Nothing! Heck, I even tried setting the appropriate value into %INC to
try and fool the module loader into thinking that the third party module
was already loaded -- to no avail.
So, can someone help me out? What on earth have I missed?
