This article details how to implement robust contract tests for the `/v1/chat/completions` API response shape, focusing on the non-deterministic nature of LLM replies. It advises developers to assert specific fields like `object` (which should be "chat.completion") and `created` (a Unix timestamp), while being permissive about newly added fields to avoid breaking tests due to vendor updates. The piece highlights the critical importance of correctly checking the `finish_reason` field to prevent data corruption from truncated responses. AI
