Refactoring and testing ejabberd XMPP server


By Erlang Central | Published: October 31, 2011



ejabberd is an open source, scalable, extendible, cross-platform
Jabber/XMPP server written in Erlang. During the last few years we have
been involved in building and optimizing a number of projects
integrating ejabberd server with various subsystems; starting from
regular IMs, going through social networks, banking, online gaming and
finishing with mobile applications. Basing on that experience we
introduced a set of refactorings applied to ejabberd sources, as well as
code optimizations, giving the machines hosting ejabberd significant
RAM savings. I will also describe escalus framework, which can be used
for blackbox testing of XMPP servers. At ESL we developed test suites
based on it, which covers some Jabber RFCs and can be used for
regression testing when XMPP server is being refactored.
