Testing HTTPS without certificate

Hi - - - ----  - --

I have a typical setup -- my development machine, a testing server  
and, of course, the production server. My development machine, of  
course, doesn't have a Secure certificate, yet I need to be able to  
test https pages here, before getting to the testing server.  
(Currently, the testing server doesn't have one either, but that will  
be remedied shortly.)

I know how to test for the existance of HTTPS, and stuff like that.

So: Can one test https on a local machine? Resources, anyone? I have  
Googled my fingers off.

Environment: PHP 5.2.5
Win 2K
IIS 5

- or, if I need to -

Mac OS-X 10.4
Apache? (I haven't set up the Mac as a server)

  - or -

Linux (Ubuntu) with Apache (I am moving this direction and haven't  
yet learned how to run Apache)
