Writing a Tsung plugin

This is a simple tutorial on writing a tsung plugin and a repost of our ProcessOne tutorial.

Since tsung is used to test servers lets define a simple server for testing. myserver.erl provides 3 operations: echo, add and subtract.

myserver.erl assumes the first byte to be a control instruction followed by 2 or more byte data. The echo operation merely returns the byte data while add and subtract performs these operations on the 2 byte data before returning the results. See the code of myserver.erl for details.

We assume the source files for tsung-1.2.1 are available. This example was compiled using Erlang OTP R11B-3.

Building a test setup for load testing with Tsung

Originally published by Emre Bastuz at https://hml.io/2015/08/04/loadtesting-with-tsung-and-multiple-ips/.

Overview

From time to time it is necessary to create multiple network sessions in a testing environment, to see how a component handles those sessions.

The following description will show a testing setup to create multiple TCP sessions by using a combination of techniques:

Setup multiple git identities & git user informations

/!\ Be very carrefull in your setup : any misconfiguration make all the git config to fail silently ! Go trought this guide step by step and it should be fine 😉

Setup multiple git ssh identities for git

• Generate your SSH keys as per your git provider documentation.
• Add each public SSH keys to your git providers acounts.
• In your ~/.ssh/config, set each ssh key for each repository as in this exemple:

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
