CI/CD Integration

These tests are designed to run in:

• GitHub Actions
• GitLab CI
• Jenkins
• Local development

See .github/workflows/test.yml for CI configuration.

Troubleshooting

Tests Failing

1. Ensure test dependencies are installed
2. Check if test server can start on port 18080
3. Verify test data directories are writable
4. Check model files are accessible

Performance Tests Failing

• Performance tests may be environment-dependent
• Adjust thresholds in test configuration if needed
• Run on dedicated test machines for consistent results

Memory Tests Failing

• Memory tests require stable baseline
• Close other applications during testing
• Use --test-threads=1 for serial execution

Contributing

When adding new integration tests:

1. Follow existing test structure
2. Add descriptive test names
3. Include error messages in assertions
4. Update this README with new tests
5. Ensure tests are deterministic and isolated
