What Test-Driven Development does

Test-Driven Development enforces a test-first workflow: write a failing test, see it fail, then write the minimum code to pass before refactoring. Use it for new features, bug fixes, refactors, and behavior changes; no production code without a failing test.

Test-Driven Development is cataloged under Quality on DirSkills. Test-Driven Development comes from a repository tagged agent-skills, agentic-coding, ai-coding, chinese and claude-code.

Documentation

README

Excerpt

测试驱动开发（TDD）

概述

先写测试。看它失败。写最少的代码让它通过。

核心原则： 如果你没有看到测试失败，你就不知道它是否测试了正确的东西。

违反规则的字面意思就是违反规则的精神。

何时使用

始终使用：

新功能
Bug 修复
重构
行为变更

例外（需询问你的人类伙伴）：

一次性原型
生成的代码
配置文件

想着"就这一次跳过 TDD"？停下来。那是在给自己找借口。

铁律

没有失败的测试，就不写生产代码

先写了代码再写测试？删掉它。从头来过。

没有例外：

不要保留作为"参考"
不要在写测试时"改编"它
不要看它
删除就是删除

从测试出发，重新实现。句号。

红-绿-重构
