Pytest VCR Workflow

Use this skill when recording or re-recording VCR cassettes for tests, or when debugging cassette contents.

Prerequisites

• Verify .env exists: test -f .env && echo 'ok' || echo 'missing'
• Missing API keys will cause clear test errors at runtime

Important flags

• --record-mode=rewrite : Record cassettes (works for both new and existing)
• --lf : Run only the last failed tests
• -vv : Verbose output
• --tb=line : Short traceback output
• -k="" : Run tests matching the given substring expression
