Can anybody share tips on using dmengine_headless for integration testing? How do you input commands? How do you verify outputs?
At King we use Cucumber to do something similar to integration testing. There’s a cucumber-lua wire protocol implementation on GitHub from which we have based our code. To this we have added non-blocking sockets that fit nicely with the Defold life-cycle of events. And on top of that we have added code to simulate user input and screen inspection to verify output. Our modifications are currently in a private repo, but perhaps it could be shared.

That sounds like a non-trivial amount of work for a lone developer like me… 
If you shared your testing solution somehow, that’d be amazing! It’d strengthen the case for Defold for sure.
I’ve gotten too used to automated testing from my web development background. I don’t want to do manual testing for anything anymore.
