i have a skill which allows people with their own instances of a specific HA sw to use Alexa. I have created a centralised backend to handle oauth2, and then allow calls from alexa to route to individuals instances. In beta it is working perfectly.
However, how do you test it? Would I need to provide an instance of the HA software for you to log in to? I can provide test credentials to handle account linking, however without the actual SW and devices, how do you test the controls are working as expected?
