execute-string

The basics of executing Gremlin queries that are NOT bound using the ExecuteStringQuery function in the Grammes client.

Description

execute-string demonstrates how to execute Gremlin queries that are NOT bound. Specifically this example shows how to execute them using the ExecuteStringQuery function in the Grammes client which takes in a string query. Then returns a []byte and error. The []byte can be used to unmarshal into any kind of expected result such as a list of vertices.

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/00security/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.
