Elasticsearch uses jUnit for testing, it also uses randomness in the
tests, that can be set using a seed, the following is a cheatsheet of
options for running the tests for ES.

== Creating packages

To create a distribution without running the tests, simply run the
following:

-----------------------------
./gradlew assemble
