White-Box Testing
Assessing AI systems with full knowledge of internal workings (code, parameters, architecture) to verify correctness, security, and compliance.
Definition
A thorough validation approach where testers inspect source code, model weights, and configuration to craft tests targeting specific logic paths, parameter ranges, and potential vulnerabilities. Governance integrates white-box tests into CI/CD pipelines, requiring coverage thresholds for critical modules, automated security‐analysis tools, and manual code reviews to ensure models behave as intended and comply with policy.
Real-World Example
A self-driving car’s perception module undergoes white-box testing: engineers inject edge-case sensor inputs directly into the model’s internal layers to verify that object-detection logic correctly handles occlusions, and static-analysis tools scan code for insecure library calls before any deployment.
