For Sagepay (it was Protx then) they have both a simulator and a test a/c that 
can be used on the live server. Their simulator never simulated reality 
exactly with various false results to waste my time on. They also use windoze 
which is case-insensitive, and I once spent half a day tracking a bug where 
they sent a case different to the one documented. The test a/c can't be used on 
3DSecure stuff, so the only way forward is to test enough that they sign off and 
let you run the module live, and then setup a cheap product item and run final 
tests on the live server. 

I've seen other testing environments that are worse. I've always found that a 
cheap product and live testing is the only way to be confident.
