## What it does

The skill splits into 8 categories by priority: test architecture and locators are critical, waiting and auth are high, mocking and Next.js integration sit in the middle, performance and CI debugging lower. Every rule has a prefix (`arch-`, `loc-`, `wait-`, `auth-`, `mock-`, `next-`, `perf-`, `debug-`) and its own file at `references/<rule-id>.md` with the reasoning plus incorrect and correct code samples.

In practice you run two commands from the project root: `npx -y @pymodel/react-frontend-skills detect` compares installed versions against target ones, and `npx -y @pymodel/react-frontend-skills scan --skill playwright` lists deprecated APIs with rule IDs. Then you open the rule files that match your task and each scan hit.

The rules assume Next.js. Hydration, Server Components, App Router navigation and Server Actions each get their own entries, so on a different framework those parts go unused. Author is PyModel, MIT licensed.

## Requirements
- Works with: Playwright

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add PyModel/react-frontend-skills --skill playwright -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/playwright/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/playwright/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add PyModel/react-frontend-skills --skill playwright -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/playwright/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add PyModel/react-frontend-skills --skill playwright -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/playwright/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install PyModel/react-frontend-skills playwright
```

2. **Manually: put the files in place**
- File: `.github/skills/playwright/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add PyModel/react-frontend-skills --skill playwright -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/PyModel/react-frontend-skills --path skills/playwright
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/playwright/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add PyModel/react-frontend-skills --skill playwright -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PyModel/react-frontend-skills/tree/HEAD/skills/playwright/SKILL.md

## When to use it
- find out why a test passes locally and fails in CI
- swap CSS selectors for role-based locators
- reuse authentication state across tests
- mock API responses for deterministic runs
- shard a large test suite

## Example prompts
- Check my Playwright tests for flakiness and apply the playwright skill rules
- Rewrite the selectors in this test to use getByRole and getByLabel
- Set up storage state for auth in my Next.js tests

# Playwright + Next.js Testing Best Practices

Comprehensive testing optimization guide for Playwright with Next.js applications. Contains 45 rules across 8 categories, prioritized by impact to guide reliable, fast, and maintainable E2E tests.

## When to Apply

Reference these guidelines when:
- Writing new Playwright tests for Next.js apps
- Debugging flaky or failing tests
- Optimizing test execution speed
- Setting up authentication state reuse
- Configuring CI/CD pipelines for testing
- Testing Server Components and App Router features
- Reviewing test code for reliability issues

## Rule Categories by Priority

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Test Architecture | CRITICAL | `arch-` |
| 2 | Selectors & Locators | CRITICAL | `loc-` |
| 3 | Waiting & Assertions | HIGH | `wait-` |
| 4 | Authentication & State | HIGH | `auth-` |
| 5 | Mocking & Network | MEDIUM-HIGH | `mock-` |
| 6 | Next.js Integration | MEDIUM | `next-` |
| 7 | Performance & Speed | MEDIUM | `perf-` |
| 8 | Debugging & CI | LOW-MEDIUM | `debug-` |

## Quick Reference

### 1. Test Architecture (CRITICAL)

- [`arch-test-isolation`](references/arch-test-isolation.md) - Use fresh browser context for each test
- [`arch-parallel-execution`](references/arch-parallel-execution.md) - Enable parallel test execution
- [`arch-page-object-model`](references/arch-page-object-model.md) - Use Page Object Model for complex pages
- [`arch-fixtures`](references/arch-fixtures.md) - Use fixtures for shared setup
- [`arch-test-production`](references/arch-test-production.md) - Test against production builds
- [`arch-cleanup-state`](references/arch-cleanup-state.md) - Clean up test state after each test

### 2. Selectors & Locators (CRITICAL)

- [`loc-role-selectors`](references/loc-role-selectors.md) - Use role-based selectors over CSS
- [`loc-data-testid`](references/loc-data-testid.md) - Use data-testid for dynamic elements
- [`loc-label-selectors`](references/loc-label-selectors.md) - Use getByLabel for form inputs
- [`loc-text-selectors`](references/loc-text-selectors.md) - Use getByText for static content
- [`loc-avoid-xpath`](references/loc-avoid-xpath.md) - Avoid XPath selectors
- [`loc-chained-locators`](references/loc-chained-locators.md) - Chain locators for specificity
- [`loc-placeholder-selector`](references/loc-placeholder-selector.md) - Use getByPlaceholder sparingly
- [`loc-frame-locator`](references/loc-frame-locator.md) - Locate elements inside iframes with frameLocator

### 3. Waiting & Assertions (HIGH)

- [`wait-web-first-assertions`](references/wait-web-first-assertions.md) - Use web-first assertions
