← Back to the catalog Use when implementing new frontend behavior, fixing bugs, or refactoring logic where tests can describe the expected behavior first. Apply to components, hooks/composables, utilities, API clients, route guards, or user workflows; Chinese triggers include TDD, 测试驱动, 先写测试, 红绿重构, 回归测试.

Design e Frontend #test by anthropics
Applies Anthropic's official brand colors and typography to any artifact that may benefit from its look-and-feel. Use it when brand colors, style guidelines, visual formatting, or company design standards apply.
Design e Frontend by anthropics
Creates distinctive, production-grade frontend interfaces with high design quality, generating creative, polished code and UI design that avoids generic AI aesthetics. Use for building web components, pages, and applications, or for styling/beautifying web UIs.
Design e Frontend #css #ai by anthropics
Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.

前端 TDD 工作流
Purpose
用“先写失败测试，再实现最小代码，再重构”的节奏交付前端功能，避免只在实现后补覆盖率。
Procedure
识别可观察行为：用户能看到的 UI、组件契约、hook/composable 返回值、路由守卫结果、API client 输出或错误状态。
先写一个最小失败测试：
纯逻辑优先单元测试。
组件交互优先 Testing Library / Vue Test Utils。
跨页关键流程优先 Playwright / Cypress。
运行该测试并确认失败原因正确，失败应来自行为尚未实现，而不是语法、导入或测试环境错误。
写刚好能通过测试的最小实现，不顺手扩大范围。
重新运行测试，确认变绿。
在测试保持通过的前提下重构命名、边界和重复逻辑。
对 bug 修复，保留能复现问题的回归测试。
每轮只扩大一个可观察行为；新需求、新边界和新异常路径各自进入下一轮。
Prove-It Pattern
修复缺陷时先让测试失败，再让它通过。若无法先失败，说明测试没有覆盖原始问题，需要收窄输入、断言或测试层级。
Frontend Test Selection
Risk Preferred Test utils、schema、状态计算 单元测试 hooks / composables 单元或轻量集成测试 组件 props、emits、交互、状态 组件测试 Router、Provider、Store 协作 轻量集成测试 登录、支付、权限、关键 CRUD E2E 测试
Constraints
不为了 TDD 引入项目没有使用且收益不清晰的新测试框架。
不测试实现细节、私有状态或脆弱 DOM 结构。
不把 E2E 当作所有风险的默认答案；优先选择离风险最近的测试层。
如果现有仓库没有测试基础设施，先输出最小测试落地建议，再请求用户确认是否引入。
不在红灯阶段同时重构；先证明问题，再最小修复，再整理结构。
Expected Output
至少一个先失败后通过的测试覆盖新增或修复行为。
实现保持最小范围，重构只在测试通过后进行。
总结运行过的测试命令、覆盖的行为和未覆盖风险。
