test-coverage

test-coverage is a command for Claude Code from zhukunpenglinyutong/ai-max. It costs 0 tokens per session (200 once invoked), scanned A, original, MIT.

A command that checks automated-test coverage and creates tests for code paths that are not tested. Test coverage measures which parts of a program are exercised by tests.

In plain words
What is it for?
Use it to run coverage reports, identify files below the stated threshold, add unit, API integration, and end-to-end tests, and verify the results.
Why use it?
It helps find untested normal cases, errors, edge cases, and important user flows instead of relying only on existing tests.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

test-coverage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

测试覆盖率

分析测试覆盖率并生成缺失的测试:

  1. 运行带覆盖率的测试:npm test --coverage 或 pnpm test --coverage

  2. 分析覆盖率报告(coverage/coverage-summary.json)

  3. 识别低于 80% 覆盖率阈值的文件

  4. 对于每个覆盖不足的文件:

    • 分析未测试的代码路径
    • 为函数生成单元测试
    • 为 API 生成集成测试
    • 为关键流程生成 E2E 测试
  5. 验证新测试通过

  6. 显示覆盖率变化前后的指标

  7. 确保项目达到 80% 以上的总体覆盖率

重点关注:

  • 正常路径场景
  • 错误处理
  • 边界情况(null、undefined、空值)
  • 边界条件

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
