+# End-to-End Testing Setup - Implementation Complete ✅
+
+This document summarizes the end-to-end testing implementation for WLED.
+
+## What Was Implemented
+
+A complete CI/CD workflow that:
+1. Builds actual WLED firmware for ESP32
+2. Runs the firmware in a Wokwi ESP32 simulator
+3. Tests the web UI using Playwright browser automation
+4. Validates that all pages load without JavaScript errors
+5. Generates detailed test reports and debugging artifacts
+
+## Files Created/Modified
+
+### GitHub Actions Workflow
+- `.github/workflows/e2e-test.yml` - Main CI workflow (223 lines)
+
+### Playwright Configuration
+- `playwright.config.js` - Playwright test configuration
+- `package.json` - Added Playwright dependencies and test scripts
+
+### Test Files
+- `tests/e2e/ui-pages.spec.js` - Tests for 12+ web UI pages (169 lines)
+
+### Documentation
+- `docs/E2E_TESTING.md` - Main E2E testing documentation
+- `docs/E2E_ALTERNATIVES.md` - Alternative approaches (ESP32 QEMU, Renode, etc.)
+- `tests/e2e/README.md` - Developer guide for E2E tests
+
+### Configuration Updates
+- `.gitignore` - Added Playwright and Wokwi artifacts
+
+## Test Coverage
+
+The automated tests validate:
+
+✅ **Main Pages:**
+- Index/home page
+- Settings page
+
+✅ **Settings Sub-pages:**
+- WiFi settings (`settings_wifi.htm`)
+- LED settings (`settings_leds.htm`)
+- UI settings (`settings_ui.htm`)
+- Sync settings (`settings_sync.htm`)
+- Time settings (`settings_time.htm`)
+- Security settings (`settings_sec.htm`)
+- DMX settings (`settings_dmx.htm`)
+- Usermod settings (`settings_um.htm`)
+- 2D settings (`settings_2D.htm`)
+
+✅ **Other Pages:**
+- Update page (`update.htm`)
+
+✅ **Validation:**
+- All pages load without errors
+- No JavaScript console errors
+- Basic navigation works
+
+## How It Works
+
+```
+Build Web UI → Build Firmware → Start Simulator → Run Tests → Report Results
+   (npm)         (PlatformIO)      (Wokwi)       (Playwright)   (Artifacts)
+```
+
+1. **Build Phase**: Compiles web UI and ESP32 firmware
+2. **Simulation Phase**: Starts Wokwi with firmware, forwards port 80→8180
+3. **Test Phase**: Playwright opens Chromium and tests each page
+4. **Report Phase**: Generates HTML reports, collects logs, uploads artifacts
+
+## Required Setup (Action Needed! 🚨)
+
+### For Repository Administrators
+
+To enable this workflow, you need to add a GitHub Secret:
+
+1. Go to https://wokwi.com/dashboard/ci
+2. Sign up/login and get a Wokwi CLI license token
+3. In this repository, go to: **Settings** → **Secrets and variables** → **Actions**
+4. Click **New repository secret**
+5. Name: `WOKWI_CLI_TOKEN`
+6. Value: Your Wokwi CLI token
+7. Click **Add secret**
+
+### Pricing Note
+
+Wokwi CLI for CI:
+- Free tier: Limited usage (check Wokwi website)
+- Paid plans: Available for commercial use
+- Alternative: See `docs/E2E_ALTERNATIVES.md` for open-source options
+
+## Running the Workflow
+
+### Automatic Triggers
+
+The workflow runs automatically on:
+- Pushes to `mdev` branch
+- Pushes to `main` branch
+- Pull requests to `mdev` or `main`
+
+### Manual Trigger
+
+1. Go to **Actions** tab
+2. Select "End-to-End Testing with ESP32 Emulation"
+3. Click **Run workflow**
+4. Select branch and click **Run workflow**
+
+## Viewing Test Results
+
+After a workflow run:
+
+1. Go to **Actions** tab
+2. Click on the workflow run
+3. View the job logs for debugging
+4. Download artifacts:
+   - **playwright-report**: HTML test report with screenshots
+   - **wokwi-logs**: Simulator console output
+
+## Troubleshooting
+
+### Workflow doesn't start
+- Ensure workflow file is on `mdev` or `main` branch
+- Check GitHub Actions are enabled for the repository
+
+### "WOKWI_CLI_TOKEN" not found
+- Add the secret as described above
+- Verify the secret name is exactly `WOKWI_CLI_TOKEN`
+
+### Simulator doesn't start
+- Check firmware built successfully
+- Look at wokwi-logs artifact for error messages
+- May need to increase timeout in workflow
+
+### Tests fail
+- Download playwright-report artifact
+- Open `index.html` in a browser
+- Review screenshots and error messages
+- Check for actual bugs in web UI or test issues
+
+## Extending the Tests
+
+To add more tests:
+
+1. Edit `tests/e2e/ui-pages.spec.js`
+2. Or create new `*.spec.js` files in `tests/e2e/`
+3. Follow the existing pattern:
+   ```javascript
+   test('my test', async ({ page }) => {
+     await page.goto('/my-page.htm');
+     await page.waitForLoadState('networkidle');
+     await expect(page.locator('body')).toBeVisible();
+   });
+   ```
+
+## Future Enhancements
+
+Possible additions:
+- [ ] API endpoint testing
+- [ ] WebSocket communication tests
+- [ ] Form submission tests
+- [ ] Effect activation tests
+- [ ] Performance benchmarks
+- [ ] Multi-browser testing (Firefox, Safari)
+- [ ] Test with ethernet build instead of WiFi
+- [ ] Test different ESP32 variants (S2, S3, C3)
+
+## Alternative Approaches
+
+If Wokwi doesn't work for your use case, see:
+- `docs/E2E_ALTERNATIVES.md` for other options:
+  - ESP32 QEMU (open source)
+  - Renode (open source)
+  - Mock HTTP server (simple, but limited)

+## Summary
+
+✅ **Complete workflow implemented**
+✅ **12+ pages tested automatically**

+
+**Next Step**: Add `WOKWI_CLI_TOKEN` secret and trigger a test run!
