* 文件名: test_p1_lcd_basic.c
|

* 作用:
|

* 对 LCD 基础模块进行单元测试，覆盖以下三个子模块：
|
||||
* 1) lcd.c : 显存初始化、像素读写、边界保护
|
||||
* 2) lcd_draw.c : 填充、反显、水平线/垂直线绘制
|
||||
* 3) lcd_text.c : UTF-8 解码、字符串显示（ASCII/中文/换行）与边界返回值
|
||||
*
|
||||
* 测试策略:
|
||||
* - 每个 test_* 函数仅验证一个明确行为域，失败即立即返回非 0。
|
||||
* - 使用 ASSERT_* 宏统一断言风格，失败时打印文件+行号。
|
||||
* - main() 串行执行所有子用例，便于定位首个失败点。
|
||||
*
|
||||
* 设计说明:
|
||||
* - 本文件只依赖公开头文件，不包含被测 .c，实现黑盒+灰盒结合验证。
|

* - 通过“像素点结果”验证绘图函数，不依赖外设或真实 LCD 硬件。
