LLM testing: Versioned golden cases as schema migrations

By PulseAugur Editorial · [1 sources] ·

This article proposes a method for managing LLM regressions by treating test cases as versioned schema migrations. It suggests using a catalog of "golden cases" that include specific inputs, expected tool calls, and assertions. These cases should be stored in JSON format to ensure stable hashing and allow for clear diffs in version control. The proposed approach emphasizes deterministic checks before subjective scoring to catch most production errors, ensuring that model outputs remain consistent even as prompts, tools, or serving models change.

    Version Golden Cases Like Schema Migrations

    <p>Silent prompt regressions rarely raise exceptions and instead arrive as answers that still parse cleanly. The durable fix is a versioned golden-case catalog whose graders fail closed rather than a larger model. Treat every fixture like a schema migration that hashes inputs and…
