These tests are intended for third-party libraries to subclass to validate that their extension arrays and dtypes satisfy the interface. Moving or renaming the tests should not be done lightly. Libraries are expected to implement a few pytest fixtures to provide data for the tests. The fixtures may be located in either * The same module as your test class. * A ``conftest.py`` in the same directory as your test class. The full list of fixtures may be found in the ``conftest.py`` next to this file. .. code-block:: python import pytest from pandas.tests.extension.base import BaseDtypeTests @pytest.fixture def dtype(): return MyDtype() class TestMyDtype(BaseDtypeTests): pass Your class ``TestDtype`` will inherit all the tests defined on ``BaseDtypeTests``. pytest's fixture discover will supply your ``dtype`` wherever the test requires it. You're free to implement additional tests. All the tests in these modules use ``self.assert_frame_equal`` or ``self.assert_series_equal`` for dataframe or series comparisons. By default, they use the usual ``pandas.testing.assert_frame_equal`` and ``pandas.testing.assert_series_equal``. You can override the checks used by defining the staticmethods ``assert_frame_equal`` and ``assert_series_equal`` on your base test class. é)ÚBaseCastingTests)ÚBaseConstructorsTests)ÚBaseDtypeTests)ÚBaseGetitemTests)ÚBaseGroupbyTests)ÚBaseInterfaceTests)ÚBaseParsingTests)ÚBaseMethodsTests)ÚBaseMissingTests)ÚBaseArithmeticOpsTestsÚBaseComparisonOpsTestsÚ BaseOpsUtilÚBaseUnaryOpsTests)ÚBasePrintingTests)ÚBaseBooleanReduceTestsÚBaseNoReduceTestsÚBaseNumericReduceTests)ÚBaseReshapingTests)ÚBaseSetitemTestsN)"Ú__doc__ZcastingrÚ constructorsrZdtyperÚgetitemrÚgroupbyrZ interfacerÚiorÚmethodsr Úmissingr Úopsr r r rZprintingrÚreducerrrZ reshapingrÚsetitemr©rrúS/home/dcms/DCMS/lib/python3.7/site-packages/pandas/tests/extension/base/__init__.pyÚ+s
