+### pytest + httpx
+
+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](https://lundberg.github.io/respx/api/#configuration).
+
+``` python
+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
+```
