NoahandClaude Fable 5.1
8805b6106c
Four review passes with fixes between them (flare-edge's flow-framework review, 2026-09-09). qmp.py: drive() split out of a 330-line dispatcher, every verb guarded so a raising verb records a fatal row instead of ending the run, the shot path sanitised, the rs485 and wait verbs judged through shared helpers; imgtools.py: a bench subcommand for phash/structural timings and a colour probe that samples instead of scanning the frame; ui-drive.sh: the boot poll no longer walks every pixel per tick and the simulator's control socket path is passed as one word. Offline tests: 8. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N3G6m9Aw5RyVY4ZowtKzEj

"""Tiny QMP client for the qemu/ device-sim tests.
|
|
|
|
qmp.py <socket> screendump <out.ppm>
|
|
qmp.py <socket> tap <x> <y> # absolute 0..32767 (virtio-tablet)
|
|
qmp.py <socket> quit
|
|
qmp.py <socket> drive <script> <outdir> [--size N]
|
|
|
|
`drive` runs a whole interaction on ONE connection, so the VM boots once and
|
|
the scenario costs a couple of seconds per step instead of a full boot. Its
|
|
script is one command per line, '#' comments and blank lines ignored, and
|
|
coordinates are PANEL PIXELS (0..size-1, default 720) rather than the
|
|
0..32767 absolute axis the raw `tap` takes -- the point of the mode is to write
|
|
"tap the gear at 47,676" straight off a screenshot.
|
|
|
|
shot NAME screendump to <outdir>/NAME.ppm
|
|
tap X Y press, hold past several LVGL poll periods, release
|
|
swipe X1 Y1 X2 Y2 [MS] drag, interpolated so LVGL sees real motion
|
|
fling X1 Y1 X2 Y2 swipe fast enough to leave momentum behind
|
|
sleep SECONDS let animations settle or timers fire
|
|
echo TEXT progress marker in the driver's own output
|
|
|
|
With `--ctl SOCK` (the unix socket run.sh --ctl creates; ui-drive.sh passes
|
|
it) the script can also ask the UI itself, through the debug channel in
|
|
warden_debug.c. The same channel is what tools/warden-ctl reaches over SSH on
|
|
a real panel, so these verbs mean the same thing on the rig and on hardware:
|
|
|
|
nav MENU[/TAB] jump to a page; fails if the page is unknown
|
|
scroll X Y DY scroll the scrollable under pixel X,Y by DY
|
|
pixels (positive reveals content below), no
|
|
animation: the deterministic stand-in for a
|
|
swipe that only brings a control into view
|
|
home close every popup and go to Dashboard/Dashboard,
|
|
the state a fresh boot starts in
|
|
wake wake the UI as if touched, minus the swallow
|
|
(sleep.c dims and then blanks an idle panel and
|
|
eats the touch that ends either); every compiled
|
|
flow script opens with it
|
|
page | stats | hit X Y print the reply, judge nothing
|
|
rs485 silence|restore ADDR
|
|
take a simulated bus device off the bus (holds its
|
|
address, answers nothing) or put it back; needs
|
|
--rs485-control (ui-drive.sh --rs485-devices)
|
|
ctl WORDS... raw passthrough for anything the channel grows
|
|
assert_page MENU/TAB the active page is exactly this
|
|
assert_hit X Y CLASS [box=X1,Y1,WxH] [TEXT...]
|
|
a real tap at X,Y lands on an object of CLASS,
|
|
with that exact box when one is given, whose
|
|
caption contains TEXT: the pre-tap self-check that
|
|
reports a MOVED button as such, not as broken
|
|
behaviour
|
|
wait_hit X Y CLASS TIMEOUT_S [box=X1,Y1,WxH] [TEXT...]
|
|
assert_hit, polled every 0.5s (poll_until) until it
|
|
holds or TIMEOUT_S elapses -- for a page still
|
|
building when the check runs
|
|
|
|
Two more channels reach behavioural state instead of the widget tree.
|
|
`--refs FILE` (default <outdir>/refs.json) is the reference store the pixel
|
|
ones read and write; imgtools.py in this directory does the actual image
|
|
math, this file only drives it.
|
|
|
|
assert_json PATH OP VALUE
|
|
wait_json PATH OP VALUE TIMEOUT_S
|
|
PATH is dotted with optional [N] indexes (e.g.
|
|
network.scan.ranges[0]) into the guest's
|
|
/tmp/warden-web-status.json, fetched fresh on
|
|
every check with `@cat` over the SAME control
|
|
channel as nav/hit (see the bridge added to
|
|
rootfs/sbin/init). OP is one of eq, ne, contains,
|
|
len_eq, len_ge, gt, lt. `wait_json` polls every
|
|
0.5s until OP holds or TIMEOUT_S elapses and
|
|
`assert_json` reads once. A PATH the document
|
|
doesn't have is a `fail`, not a crash -- that
|
|
document is a live snapshot and the key might
|
|
simply not be built yet.
|
|
assert_stat FIELD OP VALUE
|
|
FIELD is cpu, fps, render or idle (0 awake,
|
|
1 dimmed, 2 asleep), read off a fresh `stats`
|
|
reply (warden_debug.c). Same OP vocabulary as
|
|
assert_json.
|
|
capture_region NAME X Y W H TOLERANCE
|
|
screendump now, crop to X,Y,WxH, and (over)write
|
|
NAME in the refs file with both a phash and a
|
|
structural hash plus TOLERANCE (exact, loose or
|
|
structural). Run this once, by hand, to author a
|
|
reference -- the same way targets are authored,
|
|
see flows/README.md.
|
|
assert_region NAME [TOLERANCE]
|
|
fresh screendump, crop to NAME's stored box,
|
|
compare against its stored hash at its stored
|
|
tolerance. TOLERANCE, when given, must be the one
|
|
NAME was captured under (flowc.py always emits it).
|
|
wait_region NAME TOLERANCE TIMEOUT_S
|
|
assert_region, polled every 0.5s (poll_until) until
|
|
it holds or TIMEOUT_S elapses
|
|
assert_ocr NAME REGEX same crop, run through `tesseract`, REGEX searched
|
|
against the extracted text (spaces in REGEX are
|
|
fine, same as assert_hit's TEXT).
|
|
|
|
assert_region/assert_ocr against a NAME with no captured reference, and
|
|
assert_ocr with no `tesseract` on PATH, are FATAL for that one step: a
|
|
silently-skipped check reads as coverage that was never actually there. So
|
|
are a TOLERANCE that differs from the captured one and a stored box that does
|
|
not fit the screendump: both are the reference's fault, not the UI's, and one
|
|
bad reference must not take the rest of the script with it.
|
|
|
|
Every step is recorded to <outdir>/results.jsonl as ok / fail / fatal. An
|
|
assertion mismatch is a `fail` and the script continues, so one run reports
|
|
every broken expectation. With `--console LOG` the console is checked after
|
|
EVERY step for the stage-2 init's "warden-ui EXITED" line, so a crash is a
|
|
`fatal` pinned to the step that caused it rather than a stale picture found at
|
|
the end. The exit status is non-zero if anything failed.
|
|
|
|
A step that names an unknown command is a FATAL error rather than a skip: a
|
|
silently-ignored line in a scenario is a test that proves nothing.
