/**
|
||
* 并发用户测试
|
||
*
|
||
* 功能描述：
|
||
* - 测试系统在多用户并发场景下的正确性和稳定性
|
||
* - 验证并发位置更新的数据一致性
|
||
* - 确保会话管理在高并发下的可靠性
|
||
* - 测试系统的并发处理能力和性能表现
|
||
*
|
||
* 测试场景：
|
||
* - 大量用户同时连接和断开
|
||
* - 多用户同时加入/离开会话
|
||
* - 并发位置更新和广播
|
||
* - 数据竞争和一致性验证
|
||
* - 系统资源使用和清理
|
||
*
|
||
* 验证属性：
|
||
* - Property 17: Concurrent update handling (并发更新处理)
|
||
* - Property 5: Position storage consistency (位置存储一致性)
|
||
* - Property 8: Session-scoped broadcasting (会话范围广播)
|
||
* - Property 1: User session membership consistency (用户会话成员一致性)
|
||
*
|
||
* 最近修改：
|
||
* - 2026-01-08: 文件重命名 - 修正kebab-case为snake_case命名规范 (修改者: moyin)
