Background Tasks

Background tasks work with the same API as for Quart with the tasks themselves running on a nursery stored on the app, app.nursery.

Testing background tasks

By default the Quart test client is scoped to requests without any ability to run background tasks. To test with background tasks the test_app context manager must be used. This creates the nursery on the app which exists during the context. For example,

async def test_something():
    async with app.test_app() as test_app:
        assert test_app.nursery is not None
        test_client = test_app.test_client()
        test_client.get(...)
    assert app.nursery is None
