A utility for mocking out the Python HTTPX and HTTP Core libraries.
RESPX - Mock HTTPX with awesome request patterns and response side effects.
Full documentation is available at lundberg.github.io/respx
RESPX is a simple, yet powerful, utility for mocking out the HTTPX, and HTTP Core, libraries.
Start by patching HTTPX
, using
respx.mock
, then add request
routes to mock
responses.
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
experience, RESPX includes a respx_mock
fixture for easy
HTTPX
mocking, along with an optional respx
marker to fine-tune the mock
settings.
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
Install with pip:
$ pip install respx
Requires Python 3.7+ and HTTPX 0.21+. See Changelog for older HTTPX compatibility.
