6. TESTING RESULTS
================================================================================

✅ Dry-run test (2026-02-14T12:52:53Z)
   Output:
   [2026-02-14T12:52:53.451Z] Starting email digest (DRY RUN)...
   Found 0 users with preferences
   [2026-02-14T12:52:53.524Z] Digest complete: 0 email(s) sent, 0 total matches
   [DRY RUN] No emails actually sent. Run without --dry-run to send.
   
   Status: ✅ PASS (Expected 0 matches with no user preferences)

✅ Syntax validation
   - server.js: ✅ OK
   - send-digest.js: ✅ OK
   - All files pass Node.js -c check

✅ Dependencies check
   - nodemailer: ✅ 8.0.1 installed
   - pg: ✅ 8.10.0 (existing)
   - dotenv: ✅ 16.3.1 (existing)
   - express: ✅ 4.18.2 (existing)

================================================================================
7. FEATURES IMPLEMENTED
================================================================================

✅ Email Digest Matching
   - Matches keywords in tender title/description (case-insensitive)
   - Filters by tender value range (min_value to max_value)
   - Filters by location (substring match)
   - Filters by authority type (substring match)
   - Filters by sector/CPV codes
   - All conditions AND'd together

✅ Email Generation
   - Professional HTML template
   - TenderRadar branding
   - Responsive design (desktop/mobile)
   - Tender details in table format
   - Call-to-action button
   - Link to manage preferences
   - Unsubscribe link
   - HTML entity escaping for security

✅ Duplicate Prevention
   - Uses matches table to track sent emails
   - Marks matches with sent=true
   - Prevents duplicate sends to same user

✅ Error Handling
   - SMTP connection errors caught and logged
   - Database errors caught and logged
   - Process exits cleanly on error
   - All errors written to digest.log

================================================================================
8. ENVIRONMENT CONFIGURATION

2. Verify user setup:
   - Mark test users as verified in database
   - Create test user and set alert preferences

3. Monitor first run:
   - First automatic run: 2026-02-15 at 7am UTC
   - Watch logs: tail -f /home/peter/tenderpilot/digest.log

4. Test the API endpoints:
   - GET /api/alerts/preferences (retrieve preferences)
   - POST /api/alerts/preferences (set preferences)

5. Verify email delivery:
   - Check test user receives digest emails
   - Verify HTML formatting displays correctly
   - Test email links work properly

================================================================================
