/*******************************************************************************

The Neo4j Manual section numbers quoted in the test suite refer to the manual
for milestone release 1.8.  http://docs.neo4j.org/chunked/1.8/

*******************************************************************************/

/*

To run these tests, a Neo4j 1.8 instance must be running on localhost on the
default port.

If the test suite complete successfully, all new nodes & relationships created
for testing will have been deleted in cleanup.  However if the test suite fails
to complete due to a panic, the cleanup code may not get called.  Therefore it
is not recommended to run this test suite on a db containing valuable data - run
it on a throwaway testing db instead! It's possible we could reduce this risk by
using defer() for cleanup.
