Core testing clients for Sanic
Project description
Sanic Core Test
This package is meant to be the core testing utility and clients for testing Sanic applications. It is mainly derived from sanic.testing which has (or will be) removed from the main Sanic repository in the future.
Getting Started
pip install sanic-testing
The package is meant to create an almost seemless transition. Therefore, after loading the package, it will attach itself to your Sanic instance and insert test clients.
from sanic import Sanic
from sanic_testing import TestManager
sanic_app = Sanic(__name__)
TestManager(sanic_app)
This will provide access to both the sync (sanic.test_client) and async (sanic.asgi_client) clients. Both of these clients are also available directly on the TestManager instance.
Writing a sync test
Testing should be pretty much the same as when the test client was inside Sanic core. The difference is just that you need to run TestManager.
import pytest
@pytest.fixture
def app():
sanic_app = Sanic(__name__)
TestManager(sanic_app)
@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 response.body == b"foo"
assert response.status == 200
Writing an async test
Testing of an async method is best done with pytest-asyncio installed. Again, the following test should look familiar to anyone that has used asgi_client in the Sanic core package before.
The main benefit of using the asgi_client is that it is able to reach inside your application, and execute your handlers without ever having to stand up a server or make a network call.
import pytest
@pytest.fixture
def app():
sanic_app = Sanic(__name__)
TestManager(sanic_app)
@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 response.body == b"foo"
assert response.status == 200
TODO
- Create convenience decorators to inject
TestManager - Add more testing from Sanic core to make sure test clients are robust
- Add ability for reusable servers in sync testing instead of destroying them on every call
