trace-based-testing

You can convert production traces into regression tests by processing captured trace data through Python scripts, transforming problematic LLM application inputs into repeatable test cases for ongoing validation.

Trace-based testing is the process of capturing real production traces and promoting them into an evaluation set. You need it to ensure model robustness and prevent recurring bugs in LLM applications.

To generate test cases from production monitoring data, you capture problematic traces and add them to your eval set, enabling continuous evaluation and feedback to stop one-time bugs from repeating.

Yes, you can use Python scripts to process and analyze production traces, automatically adding captured cases to your evaluation set to keep it current with real production inputs for continuous improvement.

Trace analysis for bug reproduction works by directly converting captured production traces into test cases, relying on Python scripts for processing rather than requiring an external dedicated testing framework.

The best way to capture problematic traces and promote them into tests is to use trace analysis scripts that extract the specific failing inputs and add them directly to your evaluation set for validation.
