Testing Your Distributed System with Jepsen
summary
A live demo of Jepsen testing a Java Raft implementation named Barge on a five-node cluster using Clojure tooling and LightTable. It shows automated deployment of containers, injecting network partitions with a nemesis, generating reads and writes, and analyzing the recorded execution trace for linearizability; the workflow includes commands, failures encountered, the test harness code, and a postmortem that flags invariant violations or confirms expected writes (e.g., seven entries).
