Yes and a collection of flows (a bit scrolling on that page) that test or better said verify the basis functionality of the core nodes. So that when I implement Erlang-Red I can verify that its behaviour matches that of Node-RED. For regression testing these tests aren't too bad either 
Of course, it would be great if these test flows became an "official" Node-RED thing so that development both on Erlang-Red and Node-RED is testable and regression safe. Plus it would be a good way to "standardise" the set of core nodes that make up Node-RED. A kind of visual RFC/IEEE collection
Btw the unit test nodes are also available for Node-RED and should pretty much work as they do in Erlang-Red.
EDIT: for those that know my software license and dislike it, I did change the license of Erlang-Red to be gpl-3 so it's now "safe" for large corporation to use.
