capture-api-response-test-fixture

To capture API response bodies for regression testing, run a provider test script that logs the raw response JSON, then save the output into a `__fixtures__` directory for deterministic parsing assertions.

Testing streaming API responses reliably requires enabling the includeRawChunks and saveRawChunks workflow to preserve raw streamText chunks, ensuring you test against the provider's actual outputs for stable regression tests.

Store test fixtures for generateText and streamText responses by placing recorded raw response bodies or raw streaming chunks into a standardized `__fixtures__` folder, following the repository's existing naming conventions.

Provider response parsing tests fail intermittently because they do not test against the provider's actual raw outputs; capturing real API response bodies as test fixtures stabilizes response parsing and eliminates flaky test behavior.

You can trim captured API response fixtures before saving them, provided you only remove data when the semantics remain unchanged, ensuring the fixture still accurately represents the real provider response for parsing tests.
