QUESTION
I'm working with Electron and Johnny-Five to process some data I read with my Arduino Mega 2560 and I'm having some trouble testing my Arduino's connection.
This is the method I want to test (ignore the awful signature):

Answered 2022-Mar-22 at 06:25The typical approach would be moving the done
callback into the event handler. In this way, the test will wait until the callback is called. If the ready
event is not fired, the callback won't be called and the test will timeout with an error after 2 seconds.
This means that you don't need to explicitly assert that the event f
is called, and in fact, you don't event need to spy on it.

Answered 2020-Mar-19 at 11:05NPM modules referenced from the settings.js
in the functionGlobalContext
need to be installed in the userDir
because they are loaded relative to the active settings.js
file.
Both the userDIR
and settings.js
file that are in use are logged in the first few lines of output when Node-RED starts up.
You should only be editing the settings.js
file in the userDir
. The version in the Node-RED install dir is only used when setting up new userDir
's. You will also need to restart Node-RED when ever you edit this file.
