!32 Moar testing • 1000+ builds ES per day across all branches • Testing of pull requests • Testing on different operating systems • Testing on different JVMs • Testing with different garbage collectors • Testing of feature branches • Dedicated jenkins cluster for x-pack as well as other tools • Docs CI: Ensure cross reference links work • Test triage, developers take care of build failures

Slide 33

!33 Manual Testing • Small team of dedicated testers, working with developers • Exploratory testing • UI testing • Cross product testing • Integration testing with products outside of the stack

!37 Releasing - One project to build them all! • Idea: Every engineer should be able to build a release candidate • Single repo with Vagrantfile and gradle build • Requirements: Vagrant (+ winrm), VirtualBox, gradle • Vagrant image installs the technology zoo! • Builds projects, creates package repositories (+ signing) and uploads to S3 bucket, uploads to sonatype staging repo • Result: Final immutable artifacts, which are ready to be released

!43 Summary • Automate your releases with immutable releasable artifacts! • Do it as early as possible! • Ensure everyone can do a release! • Non technical aspects are incredibly harder to automate! • Does this work for you? No idea!
