check_content_pages.py — 叶子内容页像素黄金参考回归 + 文本级断言 + 往返池水位门禁。
|
||
|
||
用法：
|
||
python simulator/tests/check_content_pages.py # 文本断言 + 与本地黄金参考逐字节比对
|
||
python simulator/tests/check_content_pages.py --update # 有意改视觉后刷新本地黄金参考
|
||
前置：simulator 已构建（build/Debug/lvgl_sim.exe 存在）；纯标准库，任意 python3。
|
||
ref/*.bin 为**本地生成物、不入库**（.gitignore）：首次/换机后须先 `--update` 生成一次。
|
||
|
||
原理：① 文本级断言——解析 ui_font_cn_12.c 字形，把期望字符串（标题/标签/值/页脚）在截图
|
||
对应 y 带内做精确匹配；不依赖 ref/，先于像素比对运行，失败即中止（防误刷参考）。
|
||
② 每页用键序注入打开（info=e / ac=dee / dc=dede / pwd=ddeee 等，见 PAGES），无头截图
|
||
I1(160x160) 与 ref/shot_<page>.bin 逐字节比对——任何像素变化即 FAIL（含字体、几何、颜色）。
|
||
另做开页-关页往返池水位门禁：`es`（info）与 `ddeeesll`（密码页，ESC 后 ←← 弹出路上压的
|
||
2 个菜单框回根框，完全还原初始态）后 used 须等于 POOL_AFTER_ROUNDTRIP。
|
||
|
||
黄金参考更新流程（有意改视觉时）：先肉眼看图确认新效果正确，再 --update 刷新，
|
||
最后 regen_ref_png.py 重生成目检 PNG；误报排查见 docs/UI 设计/UI_自动化测试流程.md。
|
||
|
||
退出码：0 全 PASS；1 文本断言失败/有页不一致/池水位漂移；2 运行/环境错误（exe 缺失、参考缺失）。
