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
