 ## Testing
 
-The gem `elasticsearch-api` migrated away from the Elasticsearch REST API tests and test runner in CI. We now 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). This gives us more control on what we're testing and makes the Buildkite build way faster in Pull Requests and scheduled builds.
