tdd-workflow

tdd-workflow is a skill for Claude Code, Codex from zhukunpenglinyutong/ai-max. It costs 55 tokens per session (2,700 once invoked), scanned A, original, MIT.

A test-driven development workflow, meaning tests are written before the code, with unit, integration, and browser-based end-to-end tests.

In plain words
What is it for?
Use it when adding features, fixing bugs, refactoring code, creating API endpoints, or building components.
Why use it?
It makes expected behavior and edge cases explicit before implementation and sets a minimum combined test-coverage target of 80%.

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

tdd-workflow 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 11d 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.

测试驱动开发工作流

此 skill 确保所有代码开发遵循 TDD 原则并具有全面的测试覆盖。

何时激活

  • 编写新功能或特性
  • 修复 bug 或问题
  • 重构现有代码
  • 添加 API 端点
  • 创建新组件

核心原则

1. 代码之前先写测试

始终先写测试,然后实现代码使测试通过。

2. 覆盖率要求

  • 最低 80% 覆盖率(单元 + 集成 + E2E)
  • 覆盖所有边界情况
  • 测试错误场景
  • 验证边界条件

3. 测试类型

单元测试
  • 独立的函数和工具
  • 组件逻辑
  • 纯函数
  • 辅助函数和工具
集成测试
  • API 端点
  • 数据库操作
  • 服务交互
  • 外部 API 调用
E2E 测试(Playwright)
  • 关键用户流程
  • 完整工作流
  • 浏览器自动化
  • UI 交互

TDD 工作流步骤

步骤 1:编写用户旅程

作为 [角色],我想要 [动作],以便 [收益]

示例:
作为用户,我想要语义搜索市场,
以便即使没有精确关键词也能找到相关市场。

步骤 2:生成测试用例

为每个用户旅程创建全面的测试用例:

describe('Semantic Search', () => {
  it('returns relevant markets for query', async () => {
    // 测试实现
  })

  it('handles empty query gracefully', async () => {
    // 测试边界情况
  })

  it('falls back to substring search when Redis unavailable', async () => {
    // 测试回退行为
  })

  it('sorts results by similarity score', async () => {
    // 测试排序逻辑
  })
})

步骤 3:运行测试(它们应该失败)

npm test
# 测试应该失败 - 我们还没有实现

步骤 4:实现代码

编写最少的代码使测试通过:

// 由测试指导的实现
export async function searchMarkets(query: string) {
  // 这里是实现
}

步骤 5:再次运行测试

npm test
# 测试现在应该通过

步骤 6:重构

在保持测试绿色的情况下改进代码质量:

  • 消除重复
  • 改进命名
  • 优化性能
  • 增强可读性

步骤 7:验证覆盖率

npm run test:coverage
# 验证达到 80%+ 覆盖率

测试模式

单元测试模式(Jest/Vitest)

import { render, screen, fireEvent } from '@testing-library/react'
import { Button } from './Button'

describe('Button Component', () => {
  it('renders with correct text', () => {
    render(<Button>Click me</Button>)
    expect(screen.getByText('Click me')).toBeInTheDocument()
  })

  it('calls onClick when clicked', () => {
    const handleClick = jest.fn()
    render(<Button onClick={handleClick}>Click</Button>)

    fireEvent.click(screen.getByRole('button'))

    expect(handleClick).toHaveBeenCalledTimes(1)
  })

  it('is disabled when disabled prop is true', () => {
    render(<Button disabled>Click</Button>)
    expect(screen.getByRole('button')).toBeDisabled()
  })
})

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.

tdd-workflow is a skill published in the GitHub repository zhukunpenglinyutong/ai-max (335 stars, last pushed 7mo ago), licensed MIT. It adds 55 tokens to every session and 2,700 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
