How to delete/create databases in Neo4j?

Question

Is it possible to create/delete different databases in the graph database Neo4j like in MySQL? Or, at least, how to delete all nodes and relationships of an existing graph t

Answer 1

Run your test code on a different neo4j instance.

1. Copy your neo4j directory into a new location. Use this for testing. cd into the new directory.
2. Change the port so that you can run your tests and use it normally simultaneously. To change the port open conf/neo4j-server.properties and set org.neo4j.server.webserver.port to an unused one.
3. Start the test server on setup. Do ./neo4j stop and rm -rf data/graph.db on teardown.
