Topic: Inside the Elastic Stack: Testing and Releasing a Well Known Open Source Stack

Maintaining a well known open source stack is no easy task. Despite fixing bugs and adding features, releases need to be aligned among products and each product needs to be tested on its own. This talk starts at the lowest level of Elasticsearch, explaining how we run unit tests, moves up to integration tests, packaging tests, backwards compatibility tests, performance tests, including commercial extensions in testing phases – all of this on different operating systems and JVM versions. Attendees will get to know how our CI looks and how all of our products (Elasticsearch, Logstash, Kibana, Beats and all of its commercial extensions) are released at the same moment in order to ease the upgrade process for our end users.
