Testing payment gateways - how do you do it?

[Izi]

I always find testing payment gateways a pain in the chuff.

How do you all test them? Code - > Deploy - > test cycle?

sorry i should have been more precise, i was referring to callbacks to an actual domain. you cant test it on a local host, so every time you want to test you have to upload to a production server, under a test domain.
