Quick Start / 快速开始

bash

git diff main..feature | coverage-differ --base-coverage report.json • Compares feature branch against main using an existing coverage report, highlighting all uncovered new lines / 基于现有覆盖率报告对比特性分支与主分支，高亮所有未覆盖的新增代码行 

Features / 功能

• Detects uncovered lines in your changed code, not the entire codebase / 精准识别你修改代码中的未覆盖行，而非全量报告，帮你在开发阶段堵住漏洞 • One-click diff between any two commits or branches / 一键对比任意两个分支或提交的覆盖差异，告别手动排查 • Integrates with GitHub, GitLab, and Bitbucket PR workflows / 深度集成 GitHub、GitLab、Bitbucket 的 PR 流程，自动生成报告 • Generates blame-aware insights to identify risky changes quickly / 生成责任归属洞察，快速定位高风险未覆盖代码 • Pro: Supports incremental coverage caching for repos over 100k lines / 专业版支持增量覆盖缓存，百万行级仓库分析依然秒级响应 • Pro: Exports detailed HTML and JSON reports with trending analytics / 专业版导出含趋势分析的 HTML 与 JSON 报告，让管理层一目了然

Common Use Cases / 常见场景

• A developer adds a new API endpoint but forgets to test edge cases. The tool catches the uncovered error-handling code in the PR diff, preventing a production bug. / 开发者新增 API 端点却遗漏边缘测试，工具在 PR 中捕获未覆盖的错误处理代码，提前避免线上故障 • A team wants to enforce 80% coverage on all new code. The tool fails the CI pipeline if the changed lines fall below threshold, ensuring every commit meets quality gates. / 团队要求新代码覆盖率不低于 80%，工具在 CI 中直接拦截未达标的变更行，确保每次提交都通过质量卡口 • A code reviewer needs to focus on high-risk areas. The tool highlights only the uncovered lines the author changed, saving hours of manual inspection. / 代码审查者需要聚焦高风险区域，工具仅高亮开发者修改的未覆盖行，节省数小时人工检查时间
