What is the recommended recording mode for CI/CD?

It is recommended to use the 'none' recording mode in CI environments. This ensures that tests fail if a cassette is missing, preventing unintended live network calls during builds.

Can I use this skill with asynchronous Python code?

Yes, it provides implementation patterns for async tests using libraries like httpx and aiohttp, ensuring full compatibility with modern Python async/await workflows.

How do I handle LLM APIs that have dynamic request fields?

The skill includes a custom request matcher pattern that allows you to ignore dynamic fields such as timestamps or unique request IDs, ensuring cassettes match even when metadata changes.

How does VCR.py handle sensitive information like API keys?

The skill includes configurations to automatically redact sensitive headers like 'Authorization' and 'x-api-key', as well as logic to scrub specific fields from request bodies before they are saved to disk.

安全与测试

Automates the recording and replaying of HTTP interactions in Python tests using VCR.py to create deterministic, fast, and offline-capable test suites.

The vcr-http-recording skill integrates VCR.py into Python development workflows to capture real HTTP network traffic and save it as YAML 'cassette' files for future replay. This eliminates the need for live API calls during testing, significantly speeding up test execution, reducing costs—particularly for expensive LLM APIs—and ensuring tests remain deterministic even when external services are down. It features robust support for asynchronous clients like httpx, provides built-in mechanisms to redact sensitive data such as API keys, and includes specialized patterns for handling non-deterministic LLM request matching.
