How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

测试驱动开发(Test-Driven Development)
TDD 是红 → 绿的循环。本技能是让这个循环产出值得保留的测试的参考:好测试是什么、测试放在哪里、反模式有哪些、循环的规则是什么。每一节在每一个循环中都适用——在循环之前和之中查阅它们,而不是之后。
探索代码库时,读 GLOSSARY.md(如果存在),让测试名称和接口词汇与项目的领域语言一致,并尊重你正在触碰的区域的 ADR。
好测试是什么
测试通过公共接口验证行为,而不是实现细节。代码可以彻底改变;测试不应该。好测试读起来像一份规格——"用户可以用有效购物车结账"精确地告诉你存在什么能力——而且因为它不关心内部结构,能在重构中存活。
示例见 tests.md,mocking 指南见 mocking.md。
接缝——测试放在哪里
**接缝(seam)**是你测试所在的公共边界:在不伸手进内部的情况下观察行为的接口。测试住在接缝处,绝不对着内部。
只在预先约定的接缝处测试。 写任何测试之前,写下要测试的接缝并与用户确认。没有测试写在未经确认的接缝上。你不可能测试所有东西——提前约定接缝,正是让测试精力落在关键路径和复杂逻辑上、而不是每个边界情况上的方法。
问:"公共接口是什么,我们应该测试哪些接缝?" 为每个建议的 seam 附上一行说明,指出它能捕获什么、会漏掉什么。
当接口的形态本身存疑时——模块该有多深、接缝该在哪里、接口应该暴露什么——调用 Skill 工具并传入 "codebase-design" 来获得词汇。它是 module、interface、depth、seam、adapter、leverage、locality 这些词的共享来源,是一份供查阅的参考,而不是要跑的一场会话。
反模式
- 与实现耦合(Implementation-coupled) — mock 内部协作者、测试私有方法、或通过旁路渠道验证(查数据库而不是用接口)。识别信号:重构时行为没变,测试却挂了。
- 同义反复(Tautological) — 断言用与代码相同的方式重新计算期望值(
expect(add(a, b)).toBe(a + b)、以同样方式手工推导出的快照、断言常量等于自身),所以它构造性地通过,永远不可能与代码相左。期望值必须来自独立的真实来源——已知正确的字面量、手算的示例、规格。 - 水平切片(Horizontal slicing) — 先写完所有测试,再写所有实现。成批的测试验证的是想象出来的行为:你测试的是事物的形状而不是面向用户的行为,测试对真实变化变得不敏感,而且你在理解实现之前就锁定了测试结构。改用垂直切片——一个测试 → 一个实现 → 重复,每个测试都是一颗示踪子弹,对上一循环教会你的东西作出回应。
循环的规则
- 先红后绿。 先写会失败的测试,然后只写恰好能通过它的代码。不要预想未来的测试,也不要加投机性的功能。
- 一次一个切片。 每个循环一个接缝、一个测试、一个最小实现。
- 重构不是循环的一部分。 它属于审查阶段(见
code-review技能),不属于红 → 绿实现循环。
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
