vertices-by-label
The basics of getting vertices using the Vertices
function from a Grammes client.
Description
vertices-by-label demonstrates how to receive vertices on the graph using a Grammes client. Specifically this examples shows how to by using the Vertices
function which takes in a string
as the label. Then returns a slice of Vertex
and error
. (The Vertices
function is multi-purpose and is also seen in vertices-by-property
example).
Prerequisites
- go 1.12
- Git
- Elastic Search
- Cassandra
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/melonwool/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 to the graph
- Gathers the vertex structs that have a specific label
