Test Philosophy

KBaaS testing ensures zero-tolerance for compliance errors and 100% availability for mission-critical documentation:

1. Compliance First: Every test validates regulatory accuracy
2. AI-Driven Validation: Agents verify document integrity
3. Global Performance: Sub-second response worldwide
4. Security by Design: Penetration testing for all access paths
