PromptPex introduces a novel framework for automatically testing LLM prompts as software artifacts, ensuring robustness before deployment.

• Generates test cases by identifying different input variations and edge cases
• Evaluates prompt performance across multiple dimensions including accuracy, robustness, and security
• Detects regressions when prompts are modified, similar to traditional software testing
• Helps developers build more secure and reliable LLM-powered applications

This research bridges the gap between traditional software testing and AI prompt engineering, providing essential security guardrails for organizations deploying LLMs in production environments.
