## What it is
A Python library for mocking out the `requests` HTTP library in tests. It lets you register fake responses with matching on method, URL, headers, and body via a decorator-based API.

## Use cases
- mock http requests in python unit tests
- fake responses for the requests library
- test code that calls external apis without network
- simulate http error responses like 404 or 500 in tests
- match request bodies and query params in mocked requests
- pytest fixture for mocking requests

## When to choose
- your code uses the requests library and you need deterministic tests
- you want to simulate api failures, status codes, and payloads without a real server
- you need fine-grained request matching (headers,  bodies, query params)

## When to avoid
- your code uses httpx or aiohttp instead of requests
- you need integration tests against real or spun-up servers
- you need mocking for async http clients

## Facets
- artifact type: library
- maturity: active
- function: mocking, testing, http-client
- domain: testing, developer-tools, apis
- platform: python, cross-platform
- tags: requests-mock, http-mocking, unit-testing, pytest
