+/**
+这个单元测试是ai写的：
+
+提示词如下：
+我写了一个连接池和缓存池  请帮忙帮我写一下单元测试，以完成对池的功能检查，需要做到以下目标：
+1、连接池内的连接不共用，用完连接后需要归还到池中，通过监听ctx事件实现
+2、连接池允许连接数满后，需要等待新的连接，等待超时时间为10秒
+3、缓存池内的连接可以共用，连接超时或不可用时自动删除连接
+4、group也并发测试一下，另外对各个池做一下压力测试
+5、你通过阅读代码，尽可能多的覆盖测试
+
+回答如下:
+好的，你的需求很明确。下面我会为你的连接池（ChanPool）和缓存池（CachePool）分别设计详细的单元测试，覆盖你提到的所有核心功能点，并尽量覆盖更多边界和异常场景。
+测试会用 Go 的 testing 包实现，并会模拟一个简单的 Conn 实现用于测试。
+测试点设计说明：
+1. 连接池（ChanPool）测试点
+不同 goroutine 获取到的连接不是同一个实例。
+连接用完后归还池中，池可复用。
+连接池满时新请求会等待，超时后报错。
+连接池关闭后无法再获取连接。
+连接池 Resize 后行为正常。
+健康检查能自动剔除失效连接。
+2. 缓存池（CachePool）测试点
+获取到的连接可以复用。
+连接超时后自动删除。
+Put 超过最大连接数时，最久未用的被清理。
+池关闭后无法再获取连接。
+Resize 后行为正常。
+
+PoolGroup 并发测试：
+测试多个 goroutine 并发创建和获取连接池
+验证连接池的正确创建和管理
+基准测试：
+使用 testing.B 进行并发基准测试
+测试连接池在高并发下的性能表现
+压力测试：
+模拟真实场景下的高并发使用
+统计成功率和失败率
+测试连接池在极限情况下的表现
+异常情况测试：
+测试连接失效时的行为
+测试并发关闭时的行为
+验证连接池的健壮性
