// 单元测试：UserModel 的 JSON 解析兼容点
|
||
//
|
||
// 为什么测它：CurrentUserExtension.fromJson 里有 4 个"抗后端漂移"
|
||
// 的兼容点（见 user_model.dart 注释），任何一项回归都会导致线上
|
||
// 解析崩或字段丢，必须用测试锁死：
|
||
// ① data 包装：接口返回 {code, message, data:{...}} 时取 data；
|
||
// ② 字符串数字：userId/classId 后端可能返回 "820466383020136"；
|
||
// ③ 缺字段兜底：后端漏字段时用默认值，不闪崩；
|
||
// ④ toJson/fromJson 必须成对，否则缓存回填丢字段。
|
||
//
|
||
// 运行：flutter test test/models/user_model_test.dart
