`make test` will run the unit tests
`make test` setups a clean `vulcanize_testing` db
## Monitoring
* Enable http server and metrics using parameters `--http --metrics`
* ipld-eth-server exposes prometheus metrics at `/metric` endpoint
* start prometheus using `monitoring/prometheus.yml` config (`prometheus --config.file=monitoring/prometheus.yml`)
* start grafana, connect to prometheus datasource and import dashboard from `monitoring/grafana/dashboard_main.json`
