Pytest plugin for testing async python code
Project description
pytest-aio
pytest-aio – Is a simple pytest plugin for testing async python code
The plugin supports all popular python async libraries: (Asyncio, Trio, Curio)
pytest-aio has been strongly influenced by AnyIO. Since 2021-02-09 AnyIO has dropped support for Curio, so the plugin has been created.
Requirements
python >= 3.7
Installation
pytest-aio should be installed using pip:
pip install pytest-aio
optionally extras are available:
pip install pytest-aio[curio,trio]
Usage
When installed the plugin run all your async test functions/fixtures.
async def test_async():
assert TrueBy default each test function will be run with asyncio, trio, curio backends consistently (only if trio/curio are available). But you can customise the libraries for all your tests creating the global fixture:
# Run all tests with Asyncio/Trio only
@pytest.fixture(params=['asyncio', 'trio'])
def aiolib(request):
assert request.paramIf you want to specify different options for the selected backend, you can do so by passing a tuple of (backend name, options dict):
@pytest.fixture(params=[
pytest.param(('asyncio', {'use_uvloop': False}), id='asyncio'),
pytest.param(('asyncio', {'use_uvloop': True}), id='asyncio+uvloop'),
'trio',
pytest.param(('curio', {'debug': True}), id='curio'),
])
def aiolib(request):
assert request.paramTo set a specific backends for a single test only:
@pytest.mark.parametrize('aiolib', ['asyncio'])
async def only_with_asyncio():
await asyncio.sleep(1)
