Hello. We're planning a 5.6 -\> 6.5 upgrade here and I noticed that the local transport type has been removed in the latest version. We only use it once: for integration tests, we spin up a local ES node with `transport.type` set to `local`. May I please ask you to tell me what is the recommended way to do that moving forward? I've had a shot using `MockTcpTransportPlugin` but I'm not sure I'm doing it well as am getting loads of `transport handlers for action indices:data/write/bulk is already registered` errors. If you had a sample code somewhere that would be extremely helpful. Kind regards Regis ---

[Running Elasticsearch as an embedded node is officially no longer supported](https://www.elastic.co/blog/elasticsearch-the-server) so the recommended way to do this is to start up a separate Elasticsearch process against which to run the tests. This is how much of Elasticsearch's own test suite works. Also note that the [transport client will be deprecated](https://www.elastic.co/guide/en/elasticsearch/client/java-api/5.6/client.html#client) in favour of the [REST client](https://www.elastic.co/blog/the-elasticsearch-java-high-level-rest-client-is-out) in a future version. Running an embedded node can be useful for debugging Elasticsearch's internals. You can just use the normal TCP transport to talk to it, or use a REST client, or you can call `Node#client()` to get a client that talks to the node directly. No need to mock anything - indeed, the `MockTcpTransportPlugin` is removed in `master`. The `EsIntegTestCase` and `InternalTestCluster` classes work together to start embedded nodes for use in test cases, so perhaps it's useful to look there too. ---
