I have a Rails controller which behaves differently based on the IP  
address of the remote request. However, the defaults for functional  
tests get submitted with an IP of 0.0.0.0. How can I create a series of  
tests that use various remote IP addresses per get?

Thanks,  
Chaz

@request.env[‘REMOTE\_ADDR’] = ‘10.0.1.1’ # or whatever IP address

Do that in your setup before your test. Might be a more direct way,  
but that’s how I’ve been doing it.

Thanks, Jim – that’s exactly what I needed.
