Pytest 跳过测试说 "asyncio not installed"

Question

测试以下代码时

@pytest.mark.asynico
async def test_handle_DATA(mocker):
    handle_mock = mocker.MagicMock()
    envelope_mock = mocker.MagicMock(mail_from="Test@From", rcpt_tos=["Test@To"], content=b"TestContent")

    result = SendToDictHandler.handle_DATA(handle_mock, "TestServer", "TestSession", envelope_mock)

    assert result == "250 Message accepted for delivery"
    assert email_core.testing_emails_dict == {
        "Test@To": {
            "from": "Test@From",
            "to": ["Test@To"],
            "msg": "TestContent",
        }
    }

我在项目环境中运行 pytest -vvv 时收到的警告：

PytestWarning: Coroutine functions are not natively supported and have been skipped.
You need to install a suitable plugin for your async framework, for example:
 - pytest-asyncio
 - pytest-trio
 - pytest-tornasync
warnings.warn(PytestWarning(msg.format(pyfuncitem.nodeid)))

我确实安装了 pytest-asyncio。我在项目的虚拟环境

中通过运行pytest --trace-config验证

我会留下这个问题，以防其他人遇到这个问题。我最初的问题是我在标记中拼错了 asyncio：pytest.mark.asyncio

一旦我确定我需要等待我的回复，所以我不得不将我的测试更改为：

@staticmethod
@pytest.mark.asyncio
async def test_handle_DATA(mocker):
    handle_mock = mocker.MagicMock()
    envelope_mock = mocker.MagicMock(mail_from="Test@From", rcpt_tos=["Test@To"], content=b"TestContent")

    assert "250 Message accepted for delivery" == await SendToDictHandler.handle_DATA(
        handle_mock, "TestServer", "TestSession", envelope_mock
    )
    assert email_core.testing_emails_dict == {
        "Test@To": {
            "from": "Test@From",
            "to": ["Test@To"],
            "msg": "TestContent",
        }
    }
