Async client for testing ASGI web applications

Project description

async-asgi-testclient

Build Status PyPI version

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, ...), the same way people are doing ASGI servers like uvicorn or hypercorn that doesn't depend on the framework.

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"}
