Ruby - Is there a way to overwrite the FILE variable?

I'm doing some unit testing, and some of the code is checking to see if files exist based on the relative path of the currently-executing script by using the FILE variable. I'm doing something like this:

if File.directory?(File.join(File.dirname(__FILE__),'..','..','directory'))
    blah blah blah ...
else
    raise "Can't find directory"
end

I'm trying to find a way to make it fail in the unit tests without doing anything drastic. Being able to overwrite the __ FILE __ variable would be easiest, but as far as I can tell, it's impossible.

Any tips?
