Getting Started

Sanic Testing is the official testing client for Sanic. Its primary use is to power the tests of the Sanic project itself. However, it is also meant as an easy-to-use client for getting your API tests up and running quickly.

Minimum requirements

Python: 3.7+
Sanic: 21.3+

Versions of Sanic older than 21.3 have this module integrated into Sanic itself as sanic.testing.

Install

Sanic Testing can be installed from PyPI:

pip install sanic-testing

Basic Usage

As long as the sanic-testing package is in the environment, there is nothing you need to do to start using it.

Writing a sync test

In order to use the test client, you just need to access the property test_client on your application instance:

import pytest
from sanic import Sanic, response

@pytest.fixture
def app():
    sanic_app = Sanic("TestSanic")

    @sanic_app.get("/")
    def basic(request):
        return response.text("foo")

    return sanic_app

def test_basic_test_client(app):
    request, response = app.test_client.get("/")

    assert request.method.lower() == "get"
    assert response.body == b"foo"
    assert response.status == 200

Writing an async test

In order to use the async test client in pytest, you should install the pytest-asyncio plugin.

pip install pytest-asyncio

You can then create an async test and use the ASGI client:

import pytest
from sanic import Sanic, response

@pytest.fixture
def app():
    sanic_app = Sanic(__name__)

    @sanic_app.get("/")
    def basic(request):
        return response.text("foo")

    return sanic_app

@pytest.mark.asyncio
async def test_basic_asgi_client(app):
    request, response = await app.asgi_client.get("/")

    assert request.method.lower() == "get"
    assert response.body == b"foo"
    assert response.status == 200
