Need to write Gatling for TCP socket connection as server and as client

Question

My application uses Java and Spring Integration for Tcp connection. There are two types of features, In first I need to connect application as client and in another need to connect as server. Both are having two way communication using gateway using spring Integration.

I need to write gatling script for same, but I am new to gatling.

It would be great if there is sample program which is similar to my requirement, that I can refer as reference. Also I was not able to find any option for TCP in recorder.

Any help/pointer is really appreciated.

Answer 1

Looks like existing Spring Integration TCP Sample meets your requirements.

You can find there an XML config for the:

<int-ip:tcp-connection-factory id="crLfServer"
    type="server"
    port="${availableServerSocket}"/>

with an appropriate <int-ip:tcp-inbound-gateway> and:

<int-ip:tcp-connection-factory id="client"
    type="client"
    host="localhost"
    port="${availableServerSocket}"
    single-use="true"
    so-timeout="10000"/>

for the client side to communicate via <int-ip:tcp-outbound-gateway> .
