pytestconfig warning: unknown config option: pythonpath

This warning is displayed when an unknown configuration option pythonpath is specified in the pytest configuration file (pytest.ini or pyproject.toml) or passed as a command line argument.

Explanation:

pytest allows customizing test execution by configuring various options. These options can be defined in a pytest configuration file or passed as command line arguments. However, if an unknown option is specified, pytest displays a warning to notify that it is not a recognized configuration option.

Example:

  • Specifying an unknown option in pytest configuration file (pytest.ini):

    [pytest]
pythonpath = tests/
unknown_option = value

    In this example, the pythonpath option is a valid configuration option in pytest, but the unknown_option is not recognized. Hence, pytest will display the warning for the unknown_option.

  • Passing an unknown option as a command line argument:

    pytest --pythonpath=tests/ --unknown_option=value

    Similar to the pytest configuration file, specifying –pythonpath as a command line option is valid. However, the –unknown_option is not recognized, leading to the warning.

To resolve this warning, make sure to use valid configuration options that pytest recognizes. Refer to pytest documentation or the specific plugin’s documentation to know about the available configuration options and their usages.
