RESPX - Mock HTTPX with awesome request patterns and response side effects.

Documentation

Full documentation is available at lundberg.github.io/respx

QuickStart

RESPX is a simple, yet powerful, utility for mocking out the HTTPX, and HTTP Core, libraries.

Start by patching

HTTPX

respx.mock

import httpx
import respx

from httpx import Response
@respx.mock
def test_example():
    my_route = respx.get("https://example.org/").mock(return_value=Response(204))
    response = httpx.get("https://example.org/")
    assert my_route.called
    assert response.status_code == 204

Read the User Guide for a complete walk-through.

For a neater

pytest

HTTPX

respx

import httpx
import pytest


def test_default(respx_mock):
    respx_mock.get("https://foo.bar/").mock(return_value=httpx.Response(204))
    response = httpx.get("https://foo.bar/")
    assert response.status_code == 204
@pytest.mark.respx(base_url="https://foo.bar")
def test_with_marker(respx_mock):
    respx_mock.get("/baz/").mock(return_value=httpx.Response(204))
    response = httpx.get("https://foo.bar/baz/")
    assert response.status_code == 204

Installation

Install with pip:

$ pip install respx

Requires Python 3.6+ and HTTPX 0.20+. See Changelog for older HTTPX compatibility.
