vertex-properties-example

The basics of adding and receiving properties of a vertex on the graph using the Grammes client.

Description

vertex-properties-example demonstrates how to add and receive properties of a vertex using a Grammes client. Specifically to get the properties this example uses the ExecuteQuery function to query for the properties of a vertex with the label "person" and then unmarshals it into a PropertyList.

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/brugnara/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 vertex with various properties
  • Logs the properties from the Vertex struct
  • Shows how to gather properties from a vertex without the struct
  • Prints out the properties again after unmarshalling
