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

There is already something available - it doesn't use the IDE but does use the emulator and run it within Node.js on the command-line - it doesn't need Docker. It's at https://github.com/espruino/BangleApps/blob/master/bin/runapptests.js

It'll scan through all apps for test files of a certain format, load the app up and try and run through a test script - which eventually could involve comparing screenshots at different points (it's just a matter of including the code from https://github.com/espruino/BangleApps/blob/master/bin/thumbnailer.js).

The thing is though, there was some talk about this and I made the rough framework but nobody seems particularly bothered about actually creating any tests. For something to catch the activityreminder issue the level of tests required across all apps would be pretty high.

One thing that might be a big improvement for reliability is actually to catch any Errors created on the watch itself (or even within BangleApps) and bring them into some kind of database - but I've been resisting that as I wonder if there might be privacy implications if somehow personal data could included in the errors.
