This video was recorded at Code BEAM America 2021 - https://codesync.global/conferences/code-beam-sf-2021/ Harnessing OTP through Continuous Integration | Maxim Fedorov - Software Engineer at WhatsApp ABSTRACT Erlang/OTP is a live and breathing repository containing over two million lines of code. Over 4,300 commits were made between R23 and R24. Five years ago we started with heavily patched OTP 16 fork powering our servers. Now we run the latest version before it’s officially released, getting the most out of Erlang. This talk is about the road we took, how we ended up running OTP tests in out CI pipeline, and how we made it faster & friendlier for developers.
