Pytest helpers for AMGI applications

pytest-amgi

Pytest helpers for driving AMGI applications in-process.

Installation

pip install pytest-amgi==0.42.0

Example

This example uses AsyncFast:

from asyncfast import AsyncFast
from pytest_amgi import AMGIProducerFactory


async def test_message(amgi_producer: AMGIProducerFactory) -> None:
    app = AsyncFast()

    @app.channel("topic")
    async def handler(payload: int) -> None:
        assert payload == 1

    producer = await amgi_producer(app)
    response = await producer.send("topic", json=1)

    response.assert_acked()

The amgi_producer fixture starts lifespan before returning the producer and shuts it down when the test finishes.

Message Sends

Use assert_has_message_send to assert that the application sent a follow-up message:

from dataclasses import dataclass

from asyncfast import AsyncFast
from asyncfast import Message
from asyncfast import MessageSender
from pytest_amgi import AMGIProducerFactory


@dataclass
class ProcessOrder(Message, address="order.process"):
    payload: dict[str, int]


async def test_message_send(amgi_producer: AMGIProducerFactory) -> None:
    app = AsyncFast()

    @app.channel("order.created")
    async def handle_order_created(
        message_sender: MessageSender[ProcessOrder],
    ) -> None:
        await message_sender.send(ProcessOrder(payload={"id": 1}))

    producer = await amgi_producer(app)
    response = await producer.send("order.created")

    response.assert_acked()
    response.assert_has_message_send("order.process", json={"id": 1})
