Giacomo Vaca has published a detailed article about Kamailio Testing Framework:
It presents how to use and extend it.
The framework leverages Docker to run specific uses cases for Kamailio on many operating systems (now Debian 9, 10 and Centos 7), right now mainly targeting development and regression testing, but there is no limitation to it.
We hope that community members will start contributing to the testing framework the use cases specific for their needs, helping to ensure great software reliability and compliant SIP routing for Kamailio!
Thanks for flying Kamailio!
