First, what these nodes donotdo: These nodes have no connection outside of Node-RED. They do not directly receive data, nor do they directly send data. This is an internal system that helps you better manage Nod

We then have a set of mocha unit tests. These tests check that the node loads correctly, and ensures it makes the payload string lower case as expected. Note how the assertion failures are caught explicitly and passed to thedone()call. Node-RED swallows exceptions that are raised in the ...
