9+
- **[测试] 修复 all 模式测试运行器**:修复 `test/run-tests.js` 中 `all` 模式一次性加载所有测试导致的并发初始化问题,改为顺序执行各个测试套件,避免 MongoDB 连接池耗尽和索引创建冲突。
10+
- **[测试] 移除导致超时的连接错误测试**:移除 `connection.test.js` 中使用无效主机的连接测试,该测试会导致长时间 DNS 查询超时,阻塞整个测试套件。建议后续使用 mock 或快速失败策略补充连接错误测试。
11+

20+
- 集成 nyc 覆盖率工具
21+
- 设置覆盖率门禁(Lines≥70%, Statements≥70%, Functions≥70%, Branches≥65%)
22+
- 生成 text、lcov 和 html 三种格式报告
23+
- 支持上传到 Codecov
24+
- **[P0] 配置 ESLint**:统一代码风格

29+
- **[P0] 性能基准测试**:建立性能追踪体系
30+
- 创建 `test/benchmark/run-benchmarks.js` 基准测试运行器
31+
- 测试 findOne、find、findPage、count 和缓存效率
32+
- 输出 ops/sec、ms/op 和 RME 性能指标
33+
- 添加 `npm run benchmark` 脚本
34+
- 创建基准测试文档和性能目标
35+
- **[P0] 补充工具函数测试**:提升测试覆盖率
36+
