aiounittest 1.4.1

aiounittest

Info

The aiounittest is a helper library to ease of your pain (and boilerplate), when writing a test of the asynchronous code (asyncio). You can test:

• synchronous code (same as the unittest.TestCase)

• asynchronous code, it supports syntax with async/await (Python 3.5+) and asyncio.coroutine/yield from (Python 3.4)

In the Python 3.8 (release note) and newer consider to use the unittest.IsolatedAsyncioTestCase. Builtin unittest module is now asyncio-featured.

Installation

Use pip:

pip install aiounittest

Usage

It’s as simple as use of unittest.TestCase. Full docs at http://aiounittest.readthedocs.io.

import asyncio
import aiounittest


async def add(x, y):
    await asyncio.sleep(0.1)
    return x + y

class MyTest(aiounittest.AsyncTestCase):

    async def test_async_add(self):
        ret = await add(5, 6)
        self.assertEqual(ret, 11)

    # or 3.4 way
    @asyncio.coroutine
    def test_sleep(self):
        ret = yield from add(5, 6)
        self.assertEqual(ret, 11)

    # some regular test code
    def test_something(self):
        self.assertTrue(True)

Library provides some additional tooling:

• async_test,

• AsyncMockIterator mocking for async for,

• futurized mock for coroutines.
