[Jepsen](http://aphyr.com/posts/281-call-me-maybe-carly-rae-jepsen-and-the-perils-of-network-partitions)
is a tool written by Kyle Kingsbury that is designed to test the partition
tolerance of a distributed systems. In effect, it causes various network
partitions to take place while fuzzing the system with constant operations.
The results are analyzed to see if the system violates any of the consistency
properties it claims to have.
tolerance of distributed systems. It creates network partitions while fuzzing
the system with random operations. The results are analyzed to see if the system
violates any of the consistency properties it claims to have.
As part of our Consul testing, we ran it against Jepsen to determine if
any consistency issues could be uncovered. In our testing, we Consul
was able to gracefully recover from partitions without introducing
any consistency issues.

recovered from partitions without introducing any consistency issues.
## Running the tests
At the moment, testing with Jepsen is rather complex, as it requires
setting up multiple virtual machines, SSH setup, DNS configuration,
and a working Clojure environment. We hope to be able to contribute
our Consul testing harness upstream, and to create a Vagrant environment
to simplify the testing so that it can be done more easily.

testing code upstream and to provide a Vagrant environment for Jepsen
testing soon.
