2 # popup-constrain-test — behavioral test for submenu unconstraining in
3 # xdg_popup.rs::handle_reposition. wlroots wants the unconstrain box in the
4 # ROOT window's surface coordinates; measuring it from a submenu's parent
5 # menu instead shifted the screen by the menu's offset, so Chrome's
6 # three-dot submenus were pushed past the top edge or failed to flip.
7 #
8 # Setup: a private cce-shadow instance and verify/clients' popup-nest — a
9 # fixed-size window at a known spot with a menu and a nested submenu, each
10 # asking to flip sideways and slide vertically (what Chrome asks for).
11 # Two cases, each asserting the submenu lands fully on the 1280x720 output:
12 #
13 # 1. a tall submenu off a menu low in the window: must slide up to fit
14 # 2. a submenu off a menu near the right edge: must flip to the left
15 #
16 # Extra args pass to `cce-shadow start`, so `--bin ../target/release/cce-fx`
17 # pins the tree's own build.
