sklearn.utils.estimator_checks.parametrize_with_checks

sklearn.utils.estimator_checks.parametrize_with_checks(estimators)[source]

Pytest specific decorator for parametrizing estimator checks.

The id of each check is set to be a pprint version of the estimator and the name of the check with its keyword arguments. This allows to use pytest -k to specify which tests to run:

pytest test_check_estimators.py -k check_estimators_fit_returns_self
Parameters:
estimatorslist of estimators instances

Estimators to generated checks for.

Changed in version 0.24: Passing a class was deprecated in version 0.23, and support for classes was removed in 0.24. Pass an instance instead.

New in version 0.24.

Returns:
decoratorpytest.mark.parametrize
