Async client for testing ASGI web applications
Project description
async-asgi-testclient
Async ASGI TestClient is a library for testing web applications that implements ASGI specification (version 2 and 3).
The motivation behind this project is building a common testing library that doesn't depend on the web framework (Quart, Startlette, ...).
It works by calling the ASGI app directly. This avoids the need to run the app with a http server in a different process/thread/asyncio-loop. Since the app and test run in the same asyncio loop, it's easier to write tests and debug code.
This library is based on the testing module provided in Quart.
Quickstart
Requirements: Python 3.6+
Installation:
pip install async-asgi-testclient
Usage
my_api.py:
from quart import Quart, jsonify
app = Quart(__name__)
@app.route("/")
async def root():
return "plain response"
@app.route("/json")
async def json():
return jsonify({"hello": "world"})
if __name__ == '__main__':
app.run()
test_app.py:
from async_asgi_testclient import TestClient
import pytest
@pytest.mark.asyncio
async def test_quart_app():
from .my_api import app
async with TestClient(app) as client:
resp = await client.get("/")
assert resp.status_code == 200
assert resp.text == "plain response"
resp = await client.get("/json")
assert resp.status_code == 200
assert resp.json() == {"hello": "world"}
