+# Test Flows README
+
+To test this node, we use influxdb running in a docker container.  Currently testing with influxdb 1.6.3
+
+Set up influxdb using docker.  See documentation at https://hub.docker.com/_/influxdb/
+
+## Generating influxdb configuration
+
+We have a configuration file already set up for use with a self signed cert.  To generate a new, fresh config file locally:
+
+    docker run --rm influxdb:1.6.3 influxd config > influxdb.conf
+
+## Set up self signed certificate
+
+From the [influxdb admim documentation](https://docs.influxdata.com/influxdb/v1.6/administration/https_setup/) you can set up
+self signed SSL cert as follows:
+
+    sudo openssl req -x509 -nodes -newkey rsa:2048 -keyout ./keys/influxdb-selfsigned.key -out ./keys/influxdb-selfsigned.crt
+
+Answer the questions as you like.
+
+
+
+## Running influxdb for tests
+
+To run influxdb using the config file in the current directory:
+
+    docker run --name=influxdb -p 8086:8086 \
+      -v $PWD/influxdb.conf:/etc/influxdb/influxdb.conf:ro \
+      -v $PWD/ssl:/etc/ssl \
+      influxdb:1.6.3 -config /etc/influxdb/influxdb.conf
+
+To run the influxdb CLI against this container using a self-signed cert:
+
+    docker run --rm --link=influxdb -it influxdb influx -ssl -unsafeSsl -host influxdb
+
+You can then execute CLI commands to create databases, make queries, etc..
+
+First, create a `test database to use by the test flows.  
+
+    create database test
+
+Then import the test flows into Node-RED and ensure they work.
