check_menu_rows.py — 自绘菜单 8 状态像素回归（160x160 I1，MSB-first，1=白 0=黑）。
|
||
|
||
用法：
|
||
python simulator/tests/check_menu_rows.py # 在仓库任意目录均可运行
|
||
前置：simulator 已构建（build/Debug/lvgl_sim.exe 存在）；纯标准库，任意 python3。
|
||
|
||
状态（键序注入，u=上 d=下 e=Enter s=Esc）：
|
||
S0 "" 根框 7 行 sel=0
|
||
S1 "d" sel=1
|
||
S2 "dd" sel=2
|
||
S3 "ddu" 回退 → 须与 S1 全像素一致
|
||
S4 "de" 开 L2（实时数据 3 子项），根框不变
|
||
S5 "ded" L2 sel=1
|
||
S6 "des" 返回 → 须与 S1 全像素一致（销毁/重建一致性）
|
||
S7 "ddes" 根框 sel=2、L2 已毁 → 须与 S2 全像素一致
|
||
断言：选中行白带（白占比>0.50）+ 带内黑字；非选行黑底白字（0.03<占比<0.45）；
|
||
框体 1px 白边框；一致性状态逐字节相同；S0 池水位 = MENU_POOL_BASELINE。
|
||
|
||
退出码：0 全 PASS；1 有断言失败；2 运行/环境错误（exe 缺失等）。
