[Catalyst] Automated testing of Captcha?

[Christopher Dorman]

I am using T::W::M::C to test a page that has a (required) Captcha 
field.  In order for it to pass validation, the correct value needs to 
be passed in.

Is it possible to grab the "correct" captcha value in the test script so 
that validation can succeed, or do we need to set some environment 
variable that we check in the validation to give the field a pass?  What 
does everyone else do?
