Loopback testing

---

Loopback testing allows you to test a communications link without actually linking to another machine. You set up a connection between two queue managers as though they are on separate machines, but you test the connection by looping back to another process on the same machine. This means that you can test your communications code without requiring an active network.

The way you do this depends on which products and protocols you are using. For example the command to allow TCP/IP loopback testing on OS/2 without a network, is:

ifconfig lo ipaddress
