Browser QA — 自动化视觉测试与交互验证
When to Use / 用途
- After deploying a feature to staging/preview
- When you need to verify UI behavior across pages
- Before shipping — confirm layouts, forms, interactions actually work
- When reviewing PRs that touch frontend code
- Accessibility audits and responsive testing
- 把"前端已经改完"变成"关键页面和核心路径在浏览器里确实可用"
- 适合页面、交互、静态资源发布、关键用户路径和上线前回归确认场景
Trigger Signals / 触发信号
- 需求包含页面、组件、路由、表单、导航、权限跳转或静态资源变更
/team-release 需要关键页面 smoke 范围和发布后验证证据- 代码层测试通过了，但仍需确认真实浏览器中的渲染、交互、缓存或网络行为
- QA 或实现角色需要快速确认"关键路径能跑通"而不是一次性补完整 E2E 套件
How It Works
Uses the browser automation MCP (claude-in-chrome, Playwright, or Puppeteer) to interact with live pages like a real user.
Default Approach / 默认做法
- 先锁定 smoke 范围：目标环境、入口 URL、关键页面、核心用户路径、预期可见结果和不在本轮覆盖的内容
- 明确运行方式：优先复用当前环境可用的真实浏览器能力，例如 Playwright CLI、agent-browser 或项目已有 E2E harness；不要为了 ad-hoc smoke 临时搭一整套新测试框架
- 对动态页面，先等页面完成首屏渲染、关键请求返回或交互状态稳定，再判断是否通过；不要在骨架屏、占位态或旧缓存状态下过早下结论
- 优先验证高风险路径：页面可打开、核心导航可达、主操作可完成、关键异常态可触发、静态资源无明显 404/缓存错配
- 用截图、控制台错误、失败步骤和环境说明留下证据，并把结论回交

Phase 1: Smoke Test
1. Navigate to target URL
2. Check for console errors (filter noise: analytics, third-party)
3. Verify no 4xx/5xx in network requests
4. Screenshot above-the-fold on desktop + mobile viewport
5. Check Core Web Vitals: LCP < 2.5s, CLS < 0.1, INP < 200ms
Phase 2: Interaction Test
1. Click every nav link — verify no dead links
2. Submit forms with valid data — verify success state
3. Submit forms with invalid data — verify error state
4. Test auth flow: login → protected page → logout
5. Test critical user journeys (checkout, onboarding, search)
Phase 3: Visual Regression
1. Screenshot key pages at 3 breakpoints (375px, 768px, 1440px)
2. Compare against baseline screenshots (if stored)
3. Flag layout shifts > 5px, missing elements, overflow
4. Check dark mode if applicable
Phase 4: Accessibility
1. Run axe-core or equivalent on each page
2. Flag WCAG AA violations (contrast, labels, focus order)
3. Verify keyboard navigation works end-to-end
4. Check screen reader landmarks
Output Format
## QA Report — [URL] — [timestamp]
### Smoke Test
- Console errors: 0 critical, 2 warnings (analytics noise)
- Network: all 200/304, no failures
- Core Web Vitals: LCP 1.2s ✓, CLS 0.02 ✓, INP 89ms ✓
### Interactions
- [✓] Nav links: 12/12 working
- [✗] Contact form: missing error state for invalid email
- [✓] Auth flow: login/logout working
### Visual
- [✗] Hero section overflows on 375px viewport
- [✓] Dark mode: all pages consistent
### Accessibility
- 2 AA violations: missing alt text on hero image, low contrast on footer links
### Verdict: SHIP WITH FIXES (2 issues, 0 blockers)
Integration
Works with any browser MCP:
mChild__claude-in-chrome__* tools (preferred — uses your actual Chrome)- Playwright via
mcp__browserbase__*
- Direct Puppeteer scripts
Pair with /canary-watch for post-deploy monitoring.
