Running tests from wheel package with --pyargs ignores custom arguments

[fkromer]

I created a test only package like described here (wheel, tests deployed via data_package=). I noticed that if the tests are run on Ubuntu with pytest --pyargs <package-name> <custom-arguments> the tests are detected and run but they fail during setup because the custom command line arguments are not recognized from conftest.py. I found a workaround for this issue. Is this the recommended way to handle this my use case (deploy test only package with custom command line arguments)?

GitMate.io thinks possibly related issues are #821 (Running py.test without arguments raises missing argument error), #3198 (Ignore individual tests), #1484 (running py.test), #2371 (Running tests inside namespace packages ?), and #2544 (Run tests truly programmatically).

those need to be an actual pytest plugin in that case - early conftests are not discovered in packages

@RonnyPfannschmidt Thx for saving me time otherwise wasted for unsuccessful exploration 🙂

I know about pytest-dev/cookiecutter-pytest-plugin which creates a structure like this (only files relevant for this issue shown):

pytest-awesome/
├── pytest_awesome.py
├── setup.py
├── tests
│   ├── conftest.py
│   └── test_awesome.py
└── tox.ini

If I consider the exemplary test only package structure (inclusive their utilities, ideally importable by other packages/pytest-plugins, etc.):

• Can I place fixtures into some other file(s) instead of pytest-awesome/pytest_awesome.py as well? What's best practice for their location?
• Where should I place utilities e.g. utils.py and other_utils.py into the cookiecutter skeleton? What's best practice for their location?
• Where should I put tests for utilities e.g. test_utils.py and other_utils.py into the cookiecutter skeleton?

In essence: Is there something preventing me from structuring the package like following for a "easy" and a "full-blown" case?

Easy case with separate fixtures and utils:

pytest-awesome/
├── pytest_awesome.py
├── setup.py
├── fixtures.py
├── test_fixtures.py
├── utils.py
├── test_utils.py
├── tests
│   ├── conftest.py
│   └── test_awesome.py
└── tox.ini

Full-blown case with separate fixtures and utils:

pytest-awesome/
├── pytest_awesome.py
├── setup.py
├── fixtures
│   ├── fixtures_a.py
│   └── fixtures_b.py
├── utils
│   ├── utils_a.py
│   └── utils_b.py
├── plugin_tests
├──── fixtures
│        ├── test_fixtures_a.py
│        └── test_fixtures_b.py
├──── utils
│        ├── test_utils_a.py
│        └── test_utils_b.py
├── tests
│   ├── conftest.py
│   └── test_awesome.py
└── tox.ini
