测试结果：解释 cases 首部插入导致的多处差异

数组按下标逐项比较。在 cases 开头插入记录后，后续元素位置移动，会产生多处修改和一个尾部新增；这不等于多条业务记录都发生了真实字段变更。需要按 ID 配对时应先在自己的业务逻辑中处理。

场景与操作说明

测试结果中的 passed 仅是记录值，不证明这里执行过真实业务接口。示例用于学习如何提取和对比测试报告。

assertionCount 是示例断言数，不能直接当作用例数或覆盖率。

  1. 核对 测试结果 的字段层级，保留 caseId 的字符串类型。
  2. 修改一项输入并运行，观察结果中的值或路径如何变化。
  3. 载入对照样本，复现下面的变化；恢复原例会替换当前输入。
02

对照样本

对照样本交换 A 与 B。观察新增与删除的方向、修改前后值如何反转；没有差异时交换仍无差异。
