获得；“空套房”；在Python（V-3.8）中使用PyTest运行测试用例时出错

下面是

conftest.py

和

test_1.py

文件的代码。知道我为什么会出现“空套件”错误吗

conftest.py

import pytest


@pytest.fixture()
def setup():
    print("hi")
    yield
    print("end")

import pytest


@pytest.mark.usefixtures("setup")
class Abc:
    def test_demo(self):
        print("hello")

    def test_demo1(self):
        print("Hey")

测试1.py

import pytest


@pytest.fixture()
def setup():
    print("hi")
    yield
    print("end")

import pytest


@pytest.mark.usefixtures("setup")
class Abc:
    def test_demo(self):
        print("hello")

    def test_demo1(self):
        print("Hey")

运行

test_1.py后

获取以下消息：

将

Abc

重命名为

TestAbc

，请参见是，它现在正在@hoefling工作。这是PyTest的新标准吗？请参阅尾部链接中的注释-“测试前缀测试类中的测试前缀测试函数或方法（不带init方法）。”
