Introduction

pytest-gather-fixture is a library that builds on top of pytest-asyncio that allows you to perform asynchronous fuxtures concurrently. It is designed to be used with independent fixtures that take a long time to set up/teardown.

from pytest_gather_fixture import ConcurrentFixtureGroup

  # we create a group of fixtures that can be executed concurrently
my_group = ConcurrentFixtureGroup('my_group')

@my_group.fixture # we register a fixture within the group
async def my_async_fixture():
    await asyncio.sleep(1)
    return 'async_fixture'

@my_group.fixture # we register another fixture within the group
async def my_other_async_fixture():
    await asyncio.sleep(2)
    return 'async_fixture'

@pytest.mark.asyncio
async def test_async_fixture(async_fixture, my_other_async_fixture):
    # setup for this test will take only 2 seconds instead of 3
    assert async_fixture == 'async_fixture'
    assert my_other_async_fixture == 'async_fixture'

Note that pytest-gather-fixture is not a pytest plugin, but rather a library that can be used with pytest, and requires pytest-asyncio.
