Recommendations

Immediate (Next Steps)

  1. Deploy to staging environment for integration testing
  2. Conduct user acceptance testing with new distributions
  3. Run full QEMU/VM testing for all 25 distributions

Short Term (1-2 weeks)

  1. Replace English placeholders with proper translations (26 languages)
  2. Test mail server deployment on all new distributions
  3. Performance testing for download speeds

Long Term (1-2 months)

  1. Implement automatic mirror selection based on location
  2. Add parallel download support (multiple ISOs simultaneously)
  3. Implement automatic SHA256 checksum verification
  4. Add SELinux enforcing mode support

Running Tests

If any tests fail, run individual test suites to identify the issue:

# Translation tests
cd Website && node tests/translation-validator.js
cd Website && node tests/unit/translation-unit-tests.js
cd Website && node tests/e2e/translation-e2e-tests.js

# ISO tests
cd Core/Utils/Iso && ./test_iso_links.sh

# Recipe tests
cd Core/Utils/Iso && ./test_recipe_coverage.sh

# Project tests
./gradlew test

Troubleshooting

Issue: Download script shows "0 B/s" Solution: Wait a few seconds for speed calculation, check network connection

Issue: ISO URL validation fails Solution: Check iso_validation_report.txt for specific URL errors

Issue: Translation tests fail Solution: Run python3 fix-all-unit-test-issues.py in Website directory

Issue: Recipe coverage tests fail Solution: Verify all recipe files exist and are valid JSON
