+This repository uses the [Kitchen](https://kitchen.ci/) suite for it's tests.

+Note: The test suite uses an elasticsearch instance in order to have passing tests. Execute the following command to create a mock elasticsearch 6 instance:
+
+```bash
+docker run -d --name sensu-elasticsearch-6 docker.elastic.co/elasticsearch/elasticsearch:6.2.2
+``` 
+
+Running the tests:
+
+```bash
+bundle install --path vendor/bundle
+bundle exec kitchen test
+``` 
+
+You can find sample output for all tests running successfully in [this gist](https://gist.github.com/alexandrustaetu/d19feea1296d2ce7e367542265252d7a).
