python setup.py test unable to fine tests when using pytest

Question

My project directory looks like this

setup.py
chtools/
  __init__.py
  perspective-tool
  lib/
  tests/
    __init__.py
    setup.cfg
    test_perspective.py

when I run pytest from my project directory (i.e. same level as setup.py) everything works as expected.

(.venv) desktop:cloudhealth-tools$ pytest
platform linux -- Python 3.6.3, pytest-3.6.3, py-1.5.4, pluggy-0.6.0
rootdir: /home/jjk3/PycharmProjects/cloudhealth-tools, inifile:

chtools/tests/test_perspective.py ... [100%]

but when I run python setup test it is unable to find the tests.

(.venv) desktop:cloudhealth-tools$ python setup.py test

OK

I added setup_requires and tests_require as stated in the pytest docs, https://docs.pytest.org/en/2.9.1/goodpractices.html, but no luck.

setup.py is as follows:

from setuptools import setup, find_packages

with open('README.md') as readme_file:
    readme = readme_file.read()

setup(name='chtools',
      version='1.0.6',
      description='Automation Tools for CloudHealth',
      url='https://github.com/bluechiptek/cloudhealth-tools',

      long_description_content_type='text/markdown',
      long_description=readme,

      packages=find_packages(),
      python_requires='>=3',
      install_requires=[
            'certifi==2018.1.18',
            'chardet==3.0.4',
            'idna==2.6',
            'PyYAML==3.13',
            'requests==2.18.4',
            'urllib3==1.22'
      ],
      setup_requires=['pytest-runner'],
      tests_require=['pytest'],
      entry_points={
            'console_scripts': ['perspective-tool=chtools.perspective_tool:main']
      },
      classifiers=[
            'License :: OSI Approved :: GNU General Public License v3 (GPLv3)',
            'Programming Language :: Python :: 3 :: Only'
      ]
      )

Thanks in advance for any help!

Answer 1

Your setup.cfg resides in a wrong directory: it must be adjacent to setup.py:

chtools/
  __init__.py
  lib/
  perspective-tool
  tests/
    __init__.py
    test_perspective.py
setup.cfg
setup.py

You should declare an alias test in setup.cfg:

[aliases]
test=pytest
