test network on one pc?

Im trying to add multiplayer into my game, however, i can only test on one pc for now, how is it possible to test networking or lan on one pc. Is it even possible?
Can i have 2 running apps and send data between them on my single pc?

you need a server application installed on your computer. Try with apache server - it is a bit a mess to setup the thing, but it works

apache doesn't support blitz does it?

Setup your server app to use the loopback interface, usually at address 127.0.0.1 on your PC. You can then setup your client on the same PC and interact with the server.

Assuming your using XP, here's more info: http://support.microsoft.com/kb/839013

Using BlitzPlay, I have (in times gone by) run two or more clients versions along with a server version of a B3d programme, nothing else is needed, except the PC has to think it is conncted to a network.

As I remember I was using XPHome.

Synchronist is right, use 127.0.0.1, or "localhost". BUt you have to make sure the server port is not the same as a client port. Based on this rule you may run as many net-apps on one machine as you want and as your speed allows.

Be aware that testing on one machine leaves one serious part untested: how good is your interpolation code, because over internet there will be latency from 20-200 (+++) milliseconds and the game shouldn't end as a 5 pics per second show and interpolated the future basing on previous data.

That's why I'd prefere lan parties over mp fps across the web.

Try Microsoft virtual PC (It's Free) and do the network between the two virtual machines. or Virtual to real.
I have not tried Blitz in a virtual My self. I will and get back to you.

So Far... No 3d graphic modes are supported. For 2D it should be fine for testing networking.

No it doesn't. BlitzPlay has the ability to fake latency so you can test precisely this. Any good networking engine should have this feature.
