IT systems are related. so when validating a single system's performance, we simulate other systems related. the purpose is to 1. omit the preparation of the related system 2. ensure the related system will not be the bottleneck of the whole system.
I ever do some simple mocking system by myself, i.e. just response successful reply using TCP connection; deploy a java container to reply http response; some complex system that do async network communication. etc. recently I used the commecial product CA Lisa(says it can simulate everything),and also opensouce software SoapUI(only simulate WebService). and I want to know how about yours?
