+The integration tests on this project run the [Elasticsearch Client tests](https://github.com/elastic/elasticsearch-clients-tests/) with the [Elasticsearch Tests Runner](https://github.com/elastic/es-test-runner-ruby/) library. This runs in CI against an Elasticsearch cluster in Docker. The [Elasticsearch's REST API Spec tests](https://github.com/elastic/elasticsearch/tree/main/rest-api-spec/src/main/resources/rest-api-spec/test#test-suite) can still be ran following [these instructions](https://github.com/elastic/elasticsearch-ruby/tree/main/elasticsearch-api/api-spec-testing#readme).
