Pytest support for asyncio

Project description

https://img.shields.io/pypi/v/pytest-asyncio.svg https://github.com/pytest-dev/pytest-asyncio/workflows/CI/badge.svg https://codecov.io/gh/pytest-dev/pytest-asyncio/branch/master/graph/badge.svg Supported Python versions https://img.shields.io/badge/code%20style-black-000000.svg

pytest-asyncio is a pytest plugin. It facilitates testing of code that uses the asyncio library.

Specifically, pytest-asyncio provides support for coroutines as test functions. This allows users to await code inside their tests. For example, the following code is executed as a test item by pytest:

@pytest.mark.asyncio
async def test_some_asyncio_code():
    res = await library.do_something()
    assert b"expected result" == res

Note that test classes subclassing the standard unittest library are not supported. Users are advised to use unittest.IsolatedAsyncioTestCase or an async framework such as asynctest.

pytest-asyncio is available under the Apache License 2.0.

Installation

To install pytest-asyncio, simply:

$ pip install pytest-asyncio

This is enough for pytest to pick up pytest-asyncio.
