RED.require() function not supported in node-red-node-test-helper

[Landry25]

Dear all,
I'm trying to load a node based on new node-red dashboard api addWidget
but i have an error when loading
TypeError: RED.require is not a function
in my node I have the following code :
ui = RED.require("node-red-dashboard")(RED);
seems that require is not available in the object RED
but I use the version 0.19.5
which is working outside of the test env.

Thank you for your help.

yes you cannot test that, I cannot imagine a scenario to use this. only isolated nodes. Or very very simple and dummy nodes. I also tried a lot of things but it seems that RED instance is not loading any additional nodes.
