README

predicate-example

The basics of using predicates to narrow searches on your graph.

Description

predicate-example demonstrates how to use the Predicates to your advantage to narrow your search on the graph. Specifically this examples shows how to use them in a Traversal object to narrow the search.

Prerequisites

  • go 1.12
  • Git
  • Elastic Search
  • Cassandra
    • Java 8

Running

To run this test you will need a TinkerPop server running and a graph database to connect to locally. This example was tested while using JanusGraph which can be used by locating yourself to the root directory of the Grammes project.

cd $GOPATH/src/github.com/northwesternmutual/grammes

After locating yourself here then you may change directory to the /scripts folder.

cd scripts

Finally you may run the janusgraph.sh script to begin a local instance of JanusGraph. This will begin the TinkerPop server for you as well.

./janusgraph.sh

For further instructions please find yourself to the root README.md file.

Steps

General steps
  • Create a zap logger to help explain what's going on in the test and display the results.
  • Creates a Grammes client that connects to a locally hosted TinkerPop server with a WebSocket.
    • For testing this was created using JanusGraph. This can be run in the /scripts directory.
  • Drop all of the possible interfering vertices that were already on the graph.
  • Defer a drop of all the testing vertices. This is done as clean up.

Test specific steps
  • Adds testing vertices that have properties that can be searched
  • Gathers vertices using a search predicate
  • Prints the gathered vertices
