【问题描述】：

我在我的测试文件中导入了 pytest 并安装了 allure。我为 PATH 添加了魅力。我将目录更改为终端中的测试文件，当我使用此命令“pytest -v -s test_1.py”运行测试时，会发生此错误

您好，请在错误前插入您的测试代码（或简化版）
测试代码无所谓，因为当我在cmd中只运行pytest命令时，也会出现同样的错误。
请阅读How to Ask，然后阅读edit您的问题，并将您的代码包含为minimal reproducible example。目前，这可能会因为不清楚而被关闭。

【解决方案1】：

这是在打印“B”的测试函数之前运行打印“A”的 conftest.py 函数的示例。

cd 到父目录，在本例中为 py_tests 并运行。

pytest -s -v

输出是：

A
setting up
B
PASSED

带目录结构：

py_tests
 -conftest.py
 -tests
  --tests.py

文件：

conftest.py

import pytest

@pytest.fixture(scope="function")
def print_one():
    print("\n")
    print("A")

test.py

import pytest

class Testonething:

    @pytest.fixture(scope="function", autouse=True)
    def setup(self, print_one):
        print("setting up")

    def test_one_thing(self):
        print("B")
        assert True
