Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

测试覆盖率分析:解析 LCOV / Cobertura / Istanbul-JSON / Go cover.out 覆盖率报告,产出结构化覆盖率数据与未覆盖行区间,指导补写测试

Readme

dsh-test-coverage · 测试覆盖率分析

解析代码覆盖率报告,产出结构化、可直接指导补测试的覆盖数据。支持 LCOV(.lcov / lcov.info)、Cobertura(coverage.xml)、Istanbul / Vitest / Jest(coverage-final.json)、Go(cover.out)。纯 Node 实现,无 shell、无网络、无外部服务。

为什么需要它

Agent 跑完带覆盖率的测试后,覆盖率报告往往又大又乱。本插件把报告解析成:

  • 总体行覆盖率 + 逐文件覆盖率表(按「覆盖最低 → 最高」排序);
  • 最该补测试的文件列表;
  • 指定文件确切的未覆盖行区间,直接针对这些行补测试。

安装

dsh plugin add dsh-test-coverage

安装后在 profile 的 package.json 的 dsh.profile.bundles 中加入 "dsh-test-coverage"(或用你使用的插件市场一键安装)。

提供的工具

| 工具 | 作用 | |---|---| | coverage_report | 解析报告,返回总体覆盖率 + 逐文件表 + 覆盖最低文件 | | coverage_gaps | 返回指定文件确切的未覆盖行区间 |

用法示例

帮我看看这个项目的测试覆盖率
→ 调用 coverage_report(path="/workspace/coverage/lcov.info")

哪些行还没测到?
→ 调用 coverage_gaps(file="src/parser.js", path="/workspace/coverage")

说明

  • 本插件只做「解析与分析」,运行测试并产出覆盖率请用项目自带的测试命令(或配合其它测试插件)。
  • 大报告会自动截断(文件表最多 300 项、区间最多 400 段),避免占用过多上下文。
