# F15 test driver — NOT part of the CI contract (CI only builds and runs the
# demo binary, whose WSI_AUTO_EXIT=1 schedule self-drives the placement /
# stacking / grab-return-code probes and exits 0). This driver adds what
# needs real device input (xdotool -> XTEST): hover highlight through the
# grab, submenu hover-open, item activation, outside-click dismissal, the
# second-client starvation measurement, and Esc — each on bare Xvfb AND
# under icewm. Run it from the repo dev shell (`nix develop`, for
# dub/xvfb-run); xdotool and icewm come via `nix shell`.
#
#     ./run.sh        # build, then run all four passes, each in its own Xvfb
#
# Passes (see ../../f15-popup.md for the findings they produce):
#   A  bare Xvfb, self-driven probes (edge clamp math, XQueryTree stacking,
#      AlreadyGrabbed return code)
#   B  icewm, same self-driven probes (override-redirect: the WM changes
#      nothing about the popup itself)
#   C  bare Xvfb, xdotool-driven: right-click open -> hover items -> submenu
#      -> click item; reopen -> click the second client's window (the grab
#      eats it: dismissal for us, starvation for it; the contrast click
#      after dismissal reaches it); reopen -> Esc
#   D  icewm, the same choreography (coordinates re-derived from the
#      WM-placed window position via getwindowgeometry)
