You can not run elasticsearch embedded. Read this [blog post](https://www.elastic.co/blog/elasticsearch-the-server).

Note that to run integration tests (not unit tests) you would probably prefer running that in something close to a production environment, like a real elasticsearch server instance. I shared some ideas about integration testing in this thread: [In memory testing with RestHighLevelClient](https://discuss.elastic.co/t/in-memory-testing-with-resthighlevelclient/106196/6)

Also this sample project shows how to use Elasticsearch Test Classes:
