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)。
