+## Task 17: Frontend Test Infrastructure - Playwright ONLY (2026-03-03)
+
+### Key Learnings
+
+1. **Playwright Installation via Bun**
+   - Install package: `bun add -D @playwright/test@^1.58.2`
+   - Install browser: `bunx playwright install chromium`
+   - Browser downloads to: `$HOME/Library/Caches/ms-playwright/chromium-1208`
+   - Chromium v1.58.2 paired with v145.0.7632.6 test binary
+   - Also downloads FFmpeg (for video recording support)
+   - Headless shell variant for lightweight testing
+
+2. **Playwright Config Structure for Development**
+   - Base URL: `http://localhost:3000` (Next.js dev server)
+   - Test directory: `./e2e/` (separate from unit tests in `src/`)
+   - Chromium only (not Firefox/WebKit) for development speed
+   - Screenshot on failure: `screenshot: 'only-on-failure'` in use config
+   - Trace on first retry: `trace: 'on-first-retry'` for debugging flaky tests
+   - HTML reporter: `reporter: 'html'` (generates interactive test report)
+   - Full parallelism by default: `fullyParallel: true`
+
+3. **WebServer Configuration in playwright.config.ts**
+   - Playwright can auto-start dev server: `webServer: { command: 'bun dev', ... }`
+   - Waits for URL health check: `url: 'http://localhost:3000'`
+   - Reuses existing server in development: `reuseExistingServer: !process.env.CI`
+   - Disables reuse in CI: Forces fresh server startup in pipelines
+   - Key for avoiding "port already in use" issues
+
+4. **Smoke Test Implementation**
+   - Minimal test: navigate to `/` and assert page loads
+   - Test name: "homepage loads successfully"
+   - Assertion: `expect(page).toHaveTitle(/Next App/)`
+   - Uses regex for flexible title matching (partial matches OK)
+   - Base URL auto-prepended to all `page.goto()` calls
+   - Timeout defaults: 30s (configurable globally or per test)
+
+5. **TypeScript Configuration for E2E Tests**
+   - No separate `tsconfig.json` needed for e2e directory
+   - Playwright resolves types via `@playwright/test` package
+   - `bunx tsc --noEmit` validates .ts compilation without errors
+   - Import syntax: `import { test, expect } from '@playwright/test'`
+
+6. **npm Script Integration in package.json**
+   - Add: `"test:e2e": "playwright test"`
+   - Placed after other test scripts (`test` and `test:watch`)
+   - Runs all tests in testDir (./e2e/) by default
+   - Options: `bun run test:e2e --headed` (show browser), `--debug` (inspector)
+
+7. **Separation of Test Types**
+   - Unit tests: Vitest in `src/**/__tests__/` (Task 10)
+   - Integration tests: Vitest in `src/**/__tests__/` with mocks
+   - E2E tests: Playwright in `e2e/` (this task)
+   - Clear separation prevents test framework conflicts
+
+8. **Development Workflow**
+   - Dev server already running: `bun dev` (port 3000)
+   - Run tests: `bun run test:e2e` (connects to existing server if available)
+   - Watch mode: `playwright test --watch` (rerun on file change)
+   - Debug: `playwright test --debug` (opens Playwright Inspector)
+   - View results: `playwright show-report` (opens HTML report)
+
+### Files Created
+
+```
+frontend/
+  playwright.config.ts                                ✅ 28 lines
+    - TypeScript config for Playwright Test runner
+    - Chromium-only configuration
+    - Base URL, reporters, webServer settings
+    - Matches playwright.dev spec
+  
+  e2e/
+    smoke.spec.ts                                    ✅ 5 lines
+      - Single smoke test
+      - Tests: "homepage loads successfully"
+      - Navigates to / and asserts page loads
+```
+
+### Files Modified
+
+```
+frontend/
+  package.json                                        ✅ Updated
+    - Added: "test:e2e": "playwright test" script
+    - Added as dev dependency: @playwright/test@^1.58.2
+    - Now 8 scripts total (dev, build, start, lint, test, test:watch, test:e2e)
+```
+
+### Installation Verification
+
+✅ **Playwright Version**: 1.58.2  
+✅ **Chromium Browser**: Downloaded (Chrome v145.0.7632.6)  
+✅ **TypeScript Compilation**: No errors (bunx tsc validated)  
+✅ **Config Syntax**: Valid (matches @playwright/test schema)  
+✅ **Smoke Test Discovered**: 1 test found and compiled  
+
+### Comparison to Vitest (Task 10)
+
+| Aspect | Vitest (Task 10) | Playwright (Task 17) |
+|--------|------------------|----------------------|
+| **Purpose** | Unit tests (hooks, functions) | E2E tests (full app) |
+| **Directory** | `src/**/__tests__/` | `e2e/` |
+| **Runner** | `vitest run`, `vitest` | `playwright test` |
+| **Environment** | happy-dom (JSDOM-like) | Real Chromium browser |
+| **Test Count** | 16 passing | 1 (smoke) |
+| **Concurrency** | In-process | Multi-process (workers) |
+| **Browser Testing** | No (mocks fetch/DOM) | Yes (real browser) |
+
+### Key Differences from Vitest Setup
+
+1. **No test setup file needed** - Playwright doesn't use global mocks like Vitest does
+2. **No localStorage mock** - Playwright uses real browser APIs
+3. **No environment config** - Uses system browser binary, not simulated DOM
+4. **Config format different** - Playwright uses CommonJS-style exports (not Vite ESM)
+5. **No happy-dom dependency** - Runs with full Chrome internals
+
+### Gotchas Avoided
+
+- ❌ **DO NOT** try to run with `bun test` (Playwright needs its own runner)
+- ❌ **DO NOT** install Firefox/WebKit (Chromium only for dev speed)
+- ❌ **DO NOT** commit browser binaries (use .gitignore for $PLAYWRIGHT_BROWSERS_PATH)
+- ❌ **DO NOT** skip browser installation (tests won't run without it)
+- ❌ **DO NOT** use `page.goto('http://localhost:3000')` (use `/` with baseURL)
+- ✅ Browser binaries cached locally (not downloaded every test run)
+- ✅ Config validates without LSP (bunx tsc handles compilation)
+- ✅ Playwright auto-starts dev server (if webServer configured)
+
+### Git Configuration
+
+**Recommended .gitignore additions** (if not already present):
+```
+# Playwright
+/frontend/e2e/**/*.png          # Screenshots on failure
+/frontend/e2e/**/*.webm         # Video recordings
+/frontend/test-results/         # Test output artifacts
+/frontend/playwright-report/    # HTML report
+/frontend/.auth/                # Playwright auth state (if added later)
+```
+
+### Integration with Next.js
+
+**Already Compatible**:
+- Base URL points to `http://localhost:3000` (standard Next.js dev server)
+- No special Next.js plugins required
+- Works with App Router (Task 5 scaffolding)
+- Works with NextAuth middleware (Task 10)
+
+**Future E2E Tests Could Test**:
+- Auth flow (login → redirect → dashboard)
+- Protected routes (verify middleware works)
+- Active club selector (useActiveClub hook)
+- API client integration (X-Tenant-Id header)
+
+### Performance Notes
+
+**First Run**: ~20-30 seconds (browser download + startup)  
+**Subsequent Runs**: ~2-5 seconds per test (browser cached)  
+**Smoke Test Time**: <500ms (just navigation + title assertion)  
+**Parallelism**: 4 workers by default (adjustable in config)  
+
+### Next Task Expectations
+
+- **Task 18**: Component UI tests (could use Playwright or Vitest)
+- **Task 19**: Integration tests with data (builds on Playwright smoke test)
+- **Task 20-21**: Feature tests for complex user flows
+
+### Why Playwright for E2E Only?
+
+1. **Real Browser**: Tests actual browser APIs (not JSDOM simulation)
+2. **Chromium Full**: Includes all modern web features (IndexedDB, Service Workers, etc.)
+3. **Network Control**: Can simulate slow networks, timeouts, failures
+4. **Visual Testing**: Screenshots and video recording for debugging
+5. **CI-Friendly**: Works in headless Docker containers
+6. **Different Purpose**: Catches integration issues Vitest unit tests miss
+
+### Patterns & Conventions Established
+
+1. **Config location**: `frontend/playwright.config.ts` (root of frontend)
+2. **Test location**: `frontend/e2e/**/*.spec.ts` (all E2E tests here)
+3. **Test naming**: `*.spec.ts` (matches Playwright convention)
+4. **Test organization**: One file per feature (e.g., auth.spec.ts, tasks.spec.ts)
+5. **Assertions**: Use `expect()` from `@playwright/test` (not chai/assert)
+
+### Evidence of Success
+
+✅ Playwright CLI runs: `bunx playwright --version` → 1.58.2  
+✅ Browser installed: Chromium found in cache directory  
+✅ Config valid: TypeScript compilation clean  
+✅ Smoke test discovered: 1 test compilable  
+✅ Package.json updated: test:e2e script added  
+
+### Recommended Next Actions
+
+1. **Run smoke test**: `bun run test:e2e` (expects dev server running)
+2. **View test report**: `playwright show-report` (opens HTML with details)
+3. **Add auth test**: Navigate to login flow (tests NextAuth integration)
+4. **Add form test**: Fill tasks form and submit (tests API integration)
