Do I have to use an instance of elasticsearch with this or does this spin up a cluster/node all by itself?  
Would I be able to supply it mock data and query it like a normal elastic search node? Any good guides out there?

Thanks

Jonathan

It spins up a cluster all by itself. It is really designed for testing Elasticsearch plugins rather than client applications. Things like scripting and reindex won't be available. For client applications it is usually better to run against a real version of elasticsearch.
