Building a regression test suite for a voice agent

Why this matters

A prompt or integration change can fix one scenario and break another. A small stable test suite makes that tradeoff visible before release.

Recommended workflow

• Create tests from supported intents and known production failures.
• Include success, refusal, tool error, ambiguity, and escalation variants.
• Assert tool results and stored outcomes, not only conversational phrasing.
• Run the suite before and after every material change.

Quality checks

• Tests include caller interruptions and corrected details.
• Safety and scope boundaries have explicit expected outcomes.
• Failed tests block release or require documented review.

Practical takeaway

The most valuable tests preserve lessons already learned from failures.
