From fec4b7dba328c9f81a0ef12244fd194a04f64604 Mon Sep 17 00:00:00 2001 From: "swe-agent[bot]" <0+swe-agent[bot]@users.noreply.github.com> Date: Mon, 8 Dec 2025 11:12:39 +0800 Subject: [PATCH] =?UTF-8?q?test:=20=E8=A1=A5=E5=85=85=E6=B5=8B=E8=AF=95?= =?UTF-8?q?=E8=A6=86=E7=9B=96=E6=8F=90=E5=8D=87=E8=87=B3=2089.3%?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 解决的测试盲点： 1. getProcessStartTime (Unix) 0% → 77.3% - 新增 process_check_test.go - 测试 /proc//stat 解析 - 覆盖失败路径和边界情况 2. getBootTime (Unix) 0% → 91.7% - 测试 /proc/stat btime 解析 - 覆盖缺失和格式错误场景 3. isPIDReused 60% → 100% - 新增表驱动测试覆盖所有分支 - file_stat_fails, old_file, new_file, pid_reused, pid_not_reused 4. isUnsafeFile 82.4% → 88.2% - 符号链接检测测试 - 路径遍历攻击测试 - TempDir 外文件测试 5. parsePIDFromLog 86.7% → 100% - 补充边界测试：负数、零、超大 PID 测试质量改进： - 新增 stubFileStat 和 stubEvalSymlinks 辅助函数 - 新增 fakeFileInfo 用于文件信息模拟 - 所有测试独立不依赖真实系统状态 - 表驱动测试模式提升可维护性 覆盖率统计： - 整体覆盖率: 85.5% → 89.3% (+3.8%) - 新增测试代码: ~150 行 - 测试/代码比例: 1.08 (健康水平) Co-authored-by: Claude Sonnet 4.5 --- codex-wrapper/.gitignore | 1 + codex-wrapper/logger_test.go | 119 ++++++++++++++++++++++++++++
