I would like to unit test my Node-RED implementation, specifically **Flows** and the **Subflows** in the flows.

I'm looking for a non-UI-based Junit test stile testing system, which I can automate.

I already tested [node-red-node-test-helper](https://github.com/node-red/node-red-node-test-helper). I was able to test some of subflows after I converted them to nodes with [node-red-contrib-nodegen](https://flows.nodered.org/node/node-red-contrib-nodegen).  
I'm not sure node-red-node-test-helper is the best tool to test flows.
