AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

A pytest fixture that mocks httpx HTTP requests and responses during testing, allowing you to define and verify request/response behavior without hitting real endpoints.

Low friction install with only two runtime dependencies (httpx and pytest). Actively maintained with recent release (126 days ago) and 454 repository stars; 100% test coverage and 298 passing tests indicate solid reliability.

MIT License permits free use, modification, and distribution with minimal restrictions—suitable for both open-source and proprietary projects.

Usage

pip install pytest-httpx

import httpx
import pytest

def test_mock(httpx_mock):
    httpx_mock.add_response()
    with httpx.Client() as client:
        response = client.get("https://example.com")

Requires Python 3.10 or later.

Verdict: Stable, well-maintained testing utility for httpx with permissive MIT licensing and no known vulnerabilities. Suitable for projects that need to mock HTTP interactions in pytest; active development and high test coverage provide confidence in reliability.

Needs verification

Whether the package supports all httpx client features (streaming, proxies, custom auth) in mocking scenarios.
