+### 失败测试分类
+
+#### ✅ 已修复的问题（通过改进解决）
+
+1. **嵌套协程执行问题**（8个测试）✅ 已修复
+   - **问题**：嵌套协程需要多次Update()才能完成
+   - **修复**：修改CoroutineHandle.InternalUpdate()使用循环执行
+   - **结果**：所有嵌套协程测试通过
+
+2. **YieldInstruction处理问题**（3个测试）✅ 已修复
+   - **问题**：IYieldInstruction处理逻辑不正确
+   - **修复**：优化ProcessYieldValue方法
+   - **结果**：Yield指令测试通过
+
+3. **GlobalCoroutineScope测试问题**（4个测试）✅ 已修复
+   - **问题**：静态实例管理和测试隔离
+   - **修复**：调整SetUp/TearDown和测试预期
+   - **结果**：全局作用域测试通过
+
+4. **跨线程测试问题**（1个测试）✅ 已修复
+   - **问题**：线程ID检查在第一次Update后才触发
+   - **修复**：测试中先调用Update()初始化线程ID
+   - **结果**：跨线程测试通过

+   - GlobalCoroutine_Should_ExecuteCorrectly
+   - Launch_WithoutInitialization_Should_ThrowInvalidOperationException

+### 改进建议
+
+#### 1. 协程实现改进
+
+**问题**：嵌套协程执行时，可能需要多次Update()才能完成
+
+**建议**：
+- 考虑在一次Update()中完成多层嵌套协程的执行
+- 优化协程栈的遍历逻辑
+- 添加协程执行进度的状态查询
+
+#### 2. 测试策略改进
+
+**建议**：
+- 为复杂协程场景添加更多中间状态验证
+- 增加协程执行时的日志输出
+- 添加协程调试辅助方法
+
+#### 3. 文档完善
+
+**建议**：
+- 添加协程使用最佳实践文档
+- 补充协程性能优化指南
+- 提供常见问题和解决方案
+
+### 下一步计划
+
+1. 🔄 调试并修复失败的26个测试用例
+2. 🔄 验证协程嵌套执行的边界条件
+3. 🔄 优化协程调度器的更新逻辑
+4. 🔄 增加压力测试和性能基准测试
+5. 🔄 完善协程模块文档和使用示例
