I'd like to run a few dozen of automated tests on the driver I'm working on, and lua looks useful for this. Ideally, the tests should check screen contents while they are running, but I can get by without that -- i.e. stuff some keyboard input, wait a while, stuff more input, capture a screenshot, repeat.
How can I manipulate dip switches, though? "for k,v in pairs(manager:machine():ioport().ports) do print (k) end" enumerates them, but "print (manager:machine():ioport().ports[':SA1'].fields[':'])" fails with:
attempt to index a userdata value (field ':SA1')

Instead of screenshots, I'm thinking of taking md5 hash of frame buffer; there's a pure lua impl of md5 at https://github.com/kikito/md5.lua, haven't checked yet if lua can get at the actual displayed pixels.

Looks like it currently can't put a screen shot in a buffer. It would either have to be added or you'd have to save the shot to a file then open it again.

Some progress using plan B ("stuff some keyboard input, wait a while, stuff more input, capture a screenshot, repeat") and kyua + atf + lua + pngcmp.
% kyua test
ms1201_tests.sh:t00 -> passed [0.028s]

ms1201_tests.sh:t42 -> failed: atf-check failed; see the output of the test for details [72.094s]
'passing' test just means that emulator didn't crash and screenshots match, some of the actual tests running in the emulator are failing; not sure how to report that to atf.

Apparently Lua cannot control cassette tape motor, or am I missing something?

LUA can only access port defined in the driver and not the UI inputs. I hope someone can lift eventually this limitation, but I've been unable to make it

should the cassette player buttons not be actual emulation buttons anyway? for external cassette players they should be devices, with buttons..
you might have more than one (if we emulate tape-to-tape recorders etc.)
just putting it out there, but the concept that play/stop/record with a single cassette player driven directly by the core seems to be one of the more outdated concepts we have.

we already can have more than one, if you control the cassette drive from the internal menu (you just toggle between the drives in the UI)
it's only the shortcut key that is by default mapped to drive 1 and cannot control further drives
that said, I agree it would be great to make cassette players devices with inputs rather than devices whose inputs are handled by the core, it's just a problem of finding the time to do it

Isn't the cassette interface just a serial bit stream with modulation? There are also modems and fax machines in the same theme so maybe there are some similarities that can be generalized and tested together.
Because I can
