ui-shot.sh proves touch reaches the UI in one tap. Verifying a UI change needs
a SEQUENCE -- swipe through the app rows, open a submenu, tap a tab, bring up
the keyboard -- and booting per step costs about a minute under TCG, so:
- qmp.py gains a `drive` mode: one connection, one boot, a script of
tap/swipe/fling/shot/sleep steps in PANEL PIXELS rather than the raw
0..32767 tablet axis. Swipes interpolate their motion, because LVGL decides
a gesture from the movement between indev polls and a press-then-release
with nothing in between is a click, not a scroll.
- ui-drive.sh runs such a script against a booted VM and collects the
screenshots.
It also FAILS on a UI that died mid-script. warden-ui crashing leaves its last
frame in the framebuffer, so screendumps keep returning a plausible picture of
a program that no longer exists; stage-2 init now announces the exit and its
status on the console, and ui-drive.sh greps for that after the run. This is
what caught the SIGSEGV behind flare-edge#125.
Stage-2 init also mounts devpts. The UI's Terminal page opens a PTY, so
without it that page could only ever report "no PTY available" -- it rendered,
which made a screenshot scenario look fine while the one thing the page does
was untestable.
tests/scripts/nav-stress.txt is the first committed drive script: the
navigation sequence that reproduces flare-edge#125.
