/**
|
|
* OPT-6 行为对齐测试: 对比 ai-panel.js 原 escapeHtml (div.textContent + innerHTML)
|
|
* 与 utils.js 主实现 (replace 链).
|
|
*
|
|
* 说明: 原实现依赖浏览器 DOM, Node 无法直接调用, 这里用最小 DOM stub
|
|
* 复刻 textContent -> innerHTML 的转义语义 (只转义 & < >, 不转义引号).
|
|
* utils.js 实现是其严格超集 (额外转义 " '), 因此逐字符对比断言:
|
|
* 对同一输入, utils 输出 反解实体后 必须与 stub 输出 反解实体后 一致,
|
|
* 且 utils 输出本身满足 5 个字符的转义期望.
|
|
*
|
|
* 运行: node --test docs/escape-html-behavior.test.mjs
