Concept: Run smoke tests / unit tests in custom built Espruino IDE docker images with GitHub actions

I think I could refactor that.

That would be great!

Maybe some of the asserts would be useful as a teststep in the apptests?

Yes, absolutely - I was expecting that as tests got added we might want to have some different steps in there.

How does the emulator handle "hardware" like GPS?

Right now it doesn't, but I guess a good option would be to have a test step like GPS that actually just called Bangle.emit("GPS",{....}) to fake the GPS, so then you know exactly which coordinates are being fed in and can then check that the code is doing the right thing.

As I understand it right now things like GPS power are always off in the emulator, but maybe that could be changed or we just upload some boilerplate before the test that replaces Bangle.setGPSPower() with some JS that does what we want
