spring-statemachine-jepsen

A Clojure project implementing jepsen tests for a Spring Statemachine

Usage

  • Setup nodes n1, n2, n3, n4 and n5 having a latest debian installation.
  • Install zookeeper for every node and create a cluster.
  • Build spring-statemachine-samples-web-1.0.0.BUILD-SNAPSHOT.jar and copy it to directory /root.

Jepsen tests currently doesn't install Zookeeper or spring-statemachine-samples-web so this needs to be done manually.

Zookeeper config zoo.cfg for each node looks like:

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/lib/zookeeper
clientPort=2181
server.1=0.0.0.0:2888:3888
server.2=n2:2888:3888
server.3=n3:2888:3888
server.4=n4:2888:3888
server.5=n5:2888:3888

I had to define server.1 to use 0.0.0.0 and other node configs respectively.

Run all tests:

# lein test

Run particular test:

lein test :only spring-statemachine-jepsen.core-test/send-isolated-event

Setting up eclipse

Easiest way to import clojure leiningen project into clipse is to first create a pom.xml and then create a project based on that pom.

# lein pom
# mvn eclipse:eclipse
