python - Pytest:KeyError:WindowsPath ('D:/Local_Project_Directory/Lib/site-packages/matplotlib/testing/conftest.py')

Question

我是 Pytest 的新手，一般都在开发。我正在尝试运行一个简单的 pytest 断言，但是收到错误:

KeyError: WindowsPath('D:/ireact-tester-if/Lib/site-packages/matplotlib/testing/conftest.py')

During handling of the above exception, another exception occurred:

我尝试运行的 pytest 脚本很简单:

import pytest

@pytest.fixture(scope='module')
def nominal():
    x=1
    y=2
    yield x, y

def test_one(nominal):
    assert nominal[1] > nominal[0]

我正在使用 pyenv 和 python 3.6.8，我安装了 pytest 及其所有相关库。我不知道为什么会发生这种情况。有人知道如何解决这个问题吗？

您可以指定 pytest 将使用的多个测试目录:

pytest <my_test_directory1> <my_test_directory2> <my_test_directory3>

替换<my_test_directory1>与第一个目录和 <my_test_directory2>第二个目录包含您的测试。
