[Zope-dev] create user object for testing purposes (ZUnit)

Hi, I need some help on the creation of a (dummy?) user object using Python. I am trying to test a zope product using ZUnit. I have been able to 'simulate' a request by using the makerequest.py module (Lib/Python/Testing). Here is how I used it: import makerequest app = makerequest.makerequest(Zope.app()) request = app.REQUEST Now, the REQUEST object does not contain any AUTHENTICATED_USER, and this causes me problem because my product is using the user object, in other words, the product can not be fully tested. So, is it possible create (or simulated) an AUTHENTICATED_USER in the REQUEST? if it is, then I'll like to know how. Thank for your time and help Cheers, Karim
