Question

我已经启动了一个小型Python包（基于python-telegram-bot），并希望进行基于测试的开发。所以我通过一些基本的单元测试激活了py.test。

但我总是在setup.py上收到错误，因为它需要一个命令作为参数，但py.test不提供任何错误。

以下是setup.py的缩短版本：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from setuptools import setup

requirements = [
    'python-telegram-bot>=5.3.0'
]

test_requirements = [
    'pytest>=3.0'
]

setup(
    name='project',
    version='0.1.0',
    packages=[
        'project',
    ],
    package_dir={'project':
                 'project'},
    entry_points={
        'console_scripts': [
            'project=project.cli:main'
        ]
    },
    include_package_data=True,
    install_requires=requirements,
    license="MIT license",
    zip_safe=False,
    test_suite='tests',
    tests_require=test_requirements
)

py.test结果：

我理解setup.py中的错误确实不是错误，而是py.test运行setup.py而没有任何争论的问题...但我怎样才能避免此错误毁了我的错误测试

Answer 1

使用以下文本将conftest.py文件添加到根目录：

collect_ignore = ['setup.py']

它会告诉py.test忽略setup.py。

如何避免在setup.py上使用py.test“提供无命令”
