Bug: Dependency handling for Context breaks for multiple tests #2587
Description
This happens with FastStream 0.6.*. I have a few remarks, that might helpfully narrow down the scope
- This requires one to use a RabbitRouter. Declaring the subscriber directly on the RabbitBroker leads to unbroken behavior
- This requires one to use Context(). Depends works fine
import pytest
from faststream import Context
from faststream.rabbit import TestRabbitBroker
from faststream.rabbit import RabbitBroker, RabbitRouter
router = RabbitRouter()
@router.subscriber("in-queue")
async def handle_msg(broker=Context()) -> str:
return "test"
@pytest.fixture
async def test_broker():
broker = RabbitBroker()
broker.include_router(router)
async with TestRabbitBroker(broker) as br:
yield br
async def test_correct(test_broker) -> None:
await test_broker.publish(
{},
"in-queue",
)
async def test_again(test_broker) -> None:
await test_broker.publish(
{},
"in-queue",
)The error message is:
future: <Future finished exception=1 validation error for handle_msg
broker
Field required [type=missing, input_value={'context__': <faststream...ject at 0x7dadbcb9ead0>}, input_type=dict]
