You specified "wilderness survival"- so what event do you intend to be participating in when survival becomes an issue?
This will determine what to take on a planned test run.
If you take things on the test that you would not carry, say...hiking or hunting. Then your test is invalid. Many guys on here have spent an overnight in the cold with the same items they routinely carry hiking--- to simulate and test themselves on how well they can do with the bare essentials.
I test myself to see if I can survive my car breaking down at the edge of a wilderness in nice weather- so I bring LOTS of comfort items in the car

JK, but maybe you understand what I am saying.
