Choosing the right testing strategy for LLM agentic code involves separating deterministic logic, non-deterministic tool integrations, and evaluation-based validation. You align unit tests for fixed logic, VCR for tool integrations, and TruLens evals for agent decision quality.

Use TruLens evaluations for LLM components when validating non-deterministic agent decision quality and behavior. Use unit tests for deterministic logic with fixed inputs and outputs, ensuring clear separation of concerns between evaluation-based and standard validation.

The best way to test non-deterministic behavior in LLM tool integrations is using VCR integration tests to record and replay interactions. This ensures consistent testing scopes while accommodating features exhibiting non-deterministic behavior per EP08+ guidance.

Yes, you can apply EP08+ testing guidance to codebases with LLM tool integrations. The strategy helps identify and apply the correct testing approach for features exhibiting non-deterministic behavior across development, testing, and release workflows.

Separate deterministic and evaluation-based validation in agentic code by applying explicit recommendations per EP08+ guidance. Use unit tests for deterministic components and TruLens evals for non-deterministic LLM outputs to improve reliability and safety.
