AI Testing in Commerce: Security Risks, Methods, and a Practical Checklist

AI systems in commerce platforms introduce a new class of security risks beyond traditional QA. Key threats include prompt injection via product descriptions or reviews, hallucinations producing false product info, unauthorized AI-triggered actions like refunds, data leakage, and business logic abuse. Effective AI testing requires adversarial testing across all system layers (input, data, model, output, actions), treating external content as untrusted, applying least-privilege data access, and validating outputs before rendering. Tools like Promptfoo can automate red-teaming scenarios aligned with OWASP LLM Top 10. A pre-launch checklist covers input security, data access control, output validation, permissions, monitoring, and business logic abuse prevention. Continuous testing and monitoring are essential as AI system behavior evolves over time.
