and several others.
Elastisch needs ElasticSearch running locally (
ES_CLUSTER_NAME need to be exported

To run Elastisch tests, make sure you have ElasticSearch running. It must be the same version that Elastisch depends on due to binary protocol changes between releases. project.clj or project page on Clojars can help find that out.
Finally, run all tests with
lein all test
To run only HTTP client tests, use
lein all test :ci
Elastisch uses Leiningen 2. Make sure you have it installed and then run tests against all supported Clojure versions using
lein all test
Then create a branch and make your changes on it. Once you are done with your changes and all tests pass, submit a pull request on GitHub.
