#Maintainers this pr contains unit tests that are ignored when env variables are not set , this test are the MOTIVATION for our upcoming golem integeration tests ! we will refactor this soon .

update : testing has been completed for integration , wasm component based testing is undergoing !

arangodb

• you have to run arangodb local-Instance , example

sudo docker run -d --name arangodb -e ARANGO_NO_AUTH=1 -p 8529:8529 -v arangodb_data:/var/lib/arangodb3 -v arangodb_apps:/var/lib/arangodb3-apps arangodb

Janusgraph

• you have to run janusgraph local instance to test this , example

1. we have to specify the database (cassandra) in this case , since janusgraph doesnt store data by default

sudo docker run -d --name cassandra --network janus-net -p 9042:9042 cassandra:3.11

2. we also needs to run janus-net before the above step

sudo docker network create janus-net

3. lastly we need to run janusgraph by specifying the database , channalizer ( since it servers websocket by default in this case it is web and http both) , maybe timeout .

sudo docker run -d --name janusgraph --network janus-net -e storage.backend=cassandra -e storage.hostname=cassandra -e gremlinserver.channelizer=org.apache.tinkerpop.gremlin.server.channel.WsAndHttpChannelizer -e GREMLIN_OPTS="-Dtx.max-commit-time=60000 -Dstorage.cassandra.read-consistency-level=ONE -Dstorage.cassandra.write-consistency-level=ONE" -p 8182:8182 janusgraph/janusgraph:latest

Neo4j

• we also have to run this locally , you can use official docker command for neo4j by default it runs on http , also needs auth 🔢
  docker run \ --publish=7474:7474 --publish=7687:7687 \ --volume=$HOME/neo4j/data:/data \ neo4j

Tip : i also specified the env variables for local , in golem.yaml you have to just uncomment it which ever provider your running .

also this all three are well tested under the real instances at each level , using ureq .

You need to rebase this pr by squashing all the commits in this pr into one

@noise64 thank you so much for your detailed review , adjusted as needed please take look !

Added one more request, otherwise looks good.

@noise64 ready for merge , thank you so much !
