the elasticsearch official clients. The YAML based tests describe the
operations to be executed and the obtained results that need to be tested.

The YAML tests support various operators defined in the link:/rest-api-spec/src/yamlRestTest/resources/rest-api-spec/test/README.asciidoc[rest-api-spec] and adhere to the link:/rest-api-spec/README.markdown[Elasticsearch REST API JSON specification]
In order to run the YAML tests, the relevant API specification needs
