📚 Testing Best Practices

Healthcare Testing Guidelines

  1. Patient Data Protection

    • Never use real patient data in tests
    • Anonymize all test medical information
    • Implement data retention policies for test data

  2. Multi-Tenant Testing

    • Always set tenant context in tests
    • Verify data isolation between tests
    • Clean up after each test suite

  3. Compliance Testing

    • Test all HIPAA requirements systematically
    • Validate audit trail completeness
    • Verify access control enforcement

  4. Performance Testing

    • Test with realistic healthcare data volumes
    • Validate response times for critical workflows
    • Monitor resource usage during tests

🎯 Next Steps
