## What it is
VCR.py is a Python library that records HTTP interactions to cassette files and replays them in later test runs, eliminating real network traffic. It is a Python port of Ruby's VCR library and supports pytest via pytest-recording.

## Use cases
- record and replay http requests in python tests
- make tests deterministic without hitting real apis
- speed up test suite by mocking http interactions
- run tests offline
- update recorded api responses when the api changes

## When to choose
- your python tests make http requests and you want fast, deterministic, offline runs
- you want record-once replay-many behavior like Ruby's VCR
- you use pytest and want cassette-based fixtures

## When to avoid
- you need to mock non-HTTP protocols
- you want hand-written mocks with fine-grained assertions rather than recorded responses
- you are testing the live behavior of an external API itself

## Facets
- artifact type: library
- maturity: active
- function: mocking, testing, http-client, serialization
- domain: testing, developer-tools, apis
- platform: python, cli
