undefined local variable or method `request'—in test

module within /lib. I am calling request.env['HTTP_REFERER'] and
getting the desired results as implementation in the dev env.

However, when I run my RSpec spec, I get:
undefined local variable or method `request' for

I am assuming that somehow "request" is not getting initialized when
in the test env. etc... Coming from the test/unit and Shoulda world, I
know very little about RSpec, perhaps this is playing a role in my
problem as well.

Any insight here?
