Hi--I'm trying to set up some off-device unit testing for our system, and I found my way to https://github.com/rickkas7/UnitTestLib. It's been super helpful, for at least getting some basics compiling, but I've hit some issues since then that I'm hoping someone can give me some guidance on.
Some context: I'm pretty green at all this, so apologies in an advance for silly/naive questions. In addition, I think our current setup is probably not very well structured for unit tests, so I recognize that changing that may be necessary to moving forward.
My basic question is: what should I expect to get properly mocked via UnitTestLib? I gather that using it enables me to compile code that uses at least some portions of Particle.h (String/etc). I think I have been able to get this out of it. But if my libraries make use of, say, GitHub - rickkas7/BackgroundPublishRK: Library for doing Particle publish from a worker thread or GitHub - adafruit/Adafruit_SHT4X: Arduino driver for Adafruit SHT4X temperature / humidity breakout, should this be feasible? When I try to do so, I start to hit errors like unknown type name 'os_mutex_recursive_t', or just plain 'Arduino.h' file not found.
Is this as expected--that is, are these types/libraries outside the purview of UnitTestLib? If so, do I have any options for off-device testing--e.g. via other resources like it? Some of these missing types are probably manually mockable by me, but I'm not yet sure what would happen if I followed the chain all the way--would I likely end-up at a place where I essentially needed to re-implement on-device behavior to test code that uses libraries like these?
Thanks for your help, and sorry again if these questions are inane--just trying to find my footing here.
