如何避免在setup.py中使用py.test提供的「No commands provided」

我已經啓動了一個小Python包（基於python-telegram-bot），並且希望進行基於測試的開發。所以我用幾個基本的單元測試激活了py.test。如何避免在setup.py中使用py.test提供的「No commands provided」

但我總是在setup.py上遇到錯誤，因爲它需要命令作爲參數，但py.test不提供任何參數。

這裏是setup.py縮短版本：

#!/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 
)

而且py.test結果：

我明白，這是不是一個真正的錯誤setup.py，而是與py.test運行問題setup.py沒有任何爭論......但我怎樣才能避免這個錯誤毀了我的測試？

你可以顯示你的代碼嗎？ –

@NilsWerner：謝謝。我添加了一個簡化版本的'setup.py' –

你在你的pytest配置中設置了類似'python_files = *'的東西嗎？ –

conftest.py文件添加到根目錄與下面的文字：

collect_ignore = ['setup.py']

它會告訴py.test忽略setup.py。
