Framework for testing LLM agents across behavioral, capability, and reliability dimensions with production-focused evaluation patterns.

• Covers five core evaluation areas: agent testing, benchmark design, capability assessment, reliability metrics, and regression testing
• Emphasizes statistical test evaluation (multiple runs with distribution analysis) and behavioral contract testing over single-run or string-matching approaches
• Includes adversarial testing patterns and guards against common pitfalls like benchmark overfitting, flaky tests, and data leakage
• Designed to catch production failures that benchmarks miss, recognizing that LLM agent evaluation requires non-deterministic result handling
