Question

我想在pytest-sanic中并行运行2个测试，但是当我尝试关闭该事件循环并引发以下错误时，请执行以下操作。

RuntimeError('Event loop is closed')

这是简化版代码的样子

import pytest
import json
from main import make_app

@pytest.yield_fixture
def app():
    app = make_app()
    yield app

@pytest.fixture
def test_cli(loop, app, test_client):

    return loop.run_until_complete(test_client(app))



async def test_upload_api(test_cli):
    data = {
    "urls" : "asd"
    }
    response = await test_cli.post('/v1/images/upload',data=json.dumps(data))

    assert response.status == 200

    response = await test_cli.get('/v1/images')

    assert response.status == 200

如何在同一测试用例中运行多个请求，并在后台使用异步操作运行一次。

更新：：我正在API调用中运行异步任务，并且在禁用该任务时我没有收到该错误。但是，我需要在后台执行异步任务时对其进行测试。

在请求中运行后台异步任务，而无需在pytest-sanic
