Event Capture (Logger.php) + +Logger.php provides a centralized logging mechanism that both Pixel and CAPI events use: + +```php +// Can be called directly (not via HTTP) +require_once 'Logger.php'; +E2E_Event_Logger::log_event($test_id, 'pixel', $event_data); +E2E_Event_Logger::log_event($test_id, 'capi', $event_data); +``` + +**Thread-Safe:** Uses `flock()` for file locking to prevent race conditions. + +**Output Format:** +```json +{ + "testId": "pageview-123", + "timestamp": 1762240201866, + "pixel": [ + { + "eventName": "PageView", + "eventId": "event123", + "pixelId": "1234567890", + "timestamp": 1762240201866, + "custom_data": {}, + "user_data": { "fbp": "fb.1.123.456" } + } + ], + "capi": [ + { + "event_name": "PageView", + "event_id": "event123", + "event_time": 1762240202, + "action_source": "website", + "custom_data": {}, + "user_data": { "browser_id": "fb.1.123.456" } + } + ], + "errors": [] +} +``` + +### 2. Client-Side Capture (PixelCapture.js) + +Intercepts `fbq()` calls in the browser: + +```javascript +// Inject capture script into page +await page.addInitScript(() => { + window.capturedEvents = []; + const original = window.fbq; + window.fbq = function() { + if (arguments[0] === 'track') { + window.capturedEvents.push({ + eventName: arguments[1], + customData: arguments[2] + }); + } + original.apply(this, arguments); + }; +}); + +// After action, extract events and log +const events = await page.evaluate(() => window.capturedEvents); +``` + +### 3. Server-Side Capture (API.php) + +Before sending to Facebook, log the event: + +```php +public function send_pixel_events( $pixel_id, array $events ) { + $request = new API\Pixel\Events\Request( $pixel_id, $events ); + $response = $this->perform_request( $request ); + + // Log to E2E test framework if successful + if ( $response && ! $response->has_api_error() ) { + foreach ( $events as $event ) { + $this->log_event_for_tests( $event ); + } + } + + return $response; +} +``` + +### 4. Error Capture (ErrorCapture.php) + +Captures PHP errors during test execution: + +```php +class E2E_Error_Capture { + public static function start($test_id) { + // Set custom error handler + set_error_handler(array(__CLASS__, 'error_handler')); + register_shutdown_function(array(__CLASS__, 'shutdown_handler')); + } + + public static function error_handler($errno, $errstr, $errfile, $errline) { + // Only capture Facebook plugin errors + if (strpos($errfile, 'facebook-for-woocommerce') !== false) { + self::$errors[] = array( + 'type' => $type, + 'message' => $errstr, + 'file' => $errfile, + 'line' => $errline + ); + } + } +} +``` + +### 5. Validation (EventValidator.js) + +```javascript +const result = await validator.validate('ViewContent'); + +// result = { +// passed: true/false, +// errors: [...], +// pixel: {...}, +// capi: {...}, +// phpErrors: [...] +// } +``` + +**Validation Steps:** + +1. ✅ Check for PHP errors +2. ✅ Check event exists (Pixel & CAPI) +3. ✅ Check event count matches +4. ✅ Check required top-level fields +5. ✅ Check custom_data fields +6. ✅ Check event ID matching +7. ✅ Run custom validators: + - Timestamp sync + - Value matching + - Currency matching + - Content IDs matching + - FBP/browser_id matching + +--- + +## 🚀 Running Tests + +```bash +# Install dependencies +npm install + +# Run all E2E tests +npm run test:e2e + +# Run specific test +npx playwright test tests/e2e/test.spec.js + +# Run with UI (debugging) +npx playwright test --ui + +# Run headed (see browser) +npx playwright test --headed +``` + +--- + +## 📝 Writing New Tests + +### Step 1: Add Event Schema + +```javascript +// lib/event-schemas.js +module.exports = { + MyNewEvent: { + required: { + pixel: ['eventName', 'eventId', 'pixelId', 'timestamp', 'custom_data'], + capi: ['event_name', 'event_id', 'event_time', 'action_source', 'custom_data'] + }, + custom_data: ['field1', 'field2'], + validators: { + field1: (pixel, capi) => { + return pixel.custom_data?.field1 === capi.custom_data?.field1; + } + } + } +}; +``` + +### Step 2: Write Test + +```javascript +// test.spec.js +test('MyNewEvent', async ({ page }) => { + const { testId } = await TestSetup.init(page, 'mynewevent'); + + // Simulate user action + await page.goto('/some-page/'); + await page.click('.some-button'); + await TestSetup.wait(); + + // Validate + const validator = new EventValidator(testId); + const result = await validator.validate('MyNewEvent'); + + console.log('Result:', JSON.stringify(result, null, 2)); + expect(result.passed).toBe(true); +}); +``` + +--- + +## 🐛 Debugging + +### View Captured Events + +```bash +# View raw JSON +cat tests/e2e/captured-events/pageview-123.json | jq +``` + +### Enable Debug Logging + +```javascript +// In test.spec.js +const result = await validator.validate('PageView'); +console.log('Full Result:', JSON.stringify(result, null, 2)); +``` + +### Check for PHP Errors + +```bash +# WordPress debug log +tail -f /path/to/wp-content/debug.log | grep "FB-" +``` + +### Common Issues + +**No CAPI events captured:** +- Check if test cookie is set: `facebook_test_id` +- Check if Logger.php file exists and is writable +- Check API.php logs CAPI events after successful send + +**No Pixel events captured:** +- Check if PixelCapture is started before navigation +- Check browser console for fbq errors +- Verify Pixel ID is configured + +**Validation fails:** +- Check `result.errors` array for specific failures +- Compare `result.pixel` vs `result.capi` data +- Verify schema matches actual plugin implementation + +--- + +## 🎓 Key Concepts + +### Event Deduplication + +Facebook uses `event_id` to deduplicate Pixel and CAPI events. If both have the same `event_id`, Facebook counts it as ONE event (not two). This prevents double-counting. + +```javascript +// Same event_id = deduplicated +pixel: { eventId: "event123" } +capi: { event_id: "event123" } ✅ Deduplicated! + +// Different event_id = counted twice +pixel: { eventId: "event123" } +capi: { event_id: "event456" } ❌ Double-counted! +``` + +### FBP Cookie & Browser ID + +The `_fbp` cookie (first-party Facebook Pixel cookie) should match `user_data.browser_id` in CAPI events. This helps Facebook match users across Pixel and CAPI. + +```javascript +pixel: { user_data: { fbp: "fb.1.123.456" } } +capi: { user_data: { browser_id: "fb.1.123.456" } } ✅ Match! +``` + +### Timestamp Tolerance + +Pixel and CAPI events won't have EXACT same timestamps (network latency, processing time). We allow 30 seconds tolerance. + +```javascript +pixel: { timestamp: 1762240201000 } // 1:00:01 +capi: { event_time: 1762240202 } // 1:00:02 ✅ Within 30s +``` + +--- + +## 📊 Test Output + +``` +Running 4 tests using 1 worker + + ✓ PageView (3.2s) + ✓ ViewContent (2.8s) + ✓ AddToCart (3.5s) + ✓ ViewCategory (2.9s) + + 4 passed (12.4s) +``` + +**With Failures:** + +``` + ✗ ViewContent (3.1s) + + Errors: + - Pixel custom_data missing: content_name + - CAPI custom_data missing: content_name + - Validator failed: value +``` + +--- + +## 🔮 Future Enhancements + +### TODO: +- [ ] Add more events: Search, AddPaymentInfo, Lead +- [ ] Test error scenarios (API failures, missing fields) +- [ ] Performance testing (measure event timing) +- [ ] Visual regression testing (Pixel loading) +- [ ] CI/CD integration (GitHub Actions) +- [ ] Parallel test execution (multiple browsers) +- [ ] Test data factory (create products on-demand) +- [ ] Advanced Matching validation (email, phone hashing) + +--- + +## 📚 References + +- [Facebook Pixel Documentation](https://developers.facebook.com/docs/meta-pixel) +- [Conversion API Documentation](https://developers.facebook.com/docs/marketing-api/conversions-api) +- [Event Deduplication Guide](https://developers.facebook.com/docs/marketing-api/conversions-api/deduplicate-pixel-and-server-events) +- [Playwright Documentation](https://playwright.dev) +- [Event Parameters Spreadsheet](https://docs.google.com/spreadsheets/d/1fQvDwgHgq2jz1M_zfvKzW4PR8c_OgmsIJbGrRk1zMjY) + +--- + +## 🤝 Contributing + +When adding new validations: + +1.
