.. module:: cupy.testing
CuPy offers testing utilities to support unit testing. They are under namespace :mod:`cupy.testing`.
The assertions have same names as NumPy's ones. The difference from NumPy is that they can accept both :class:`numpy.ndarray` and :class:`cupy.ndarray`.
.. autosummary:: :toctree: generated/ :nosignatures: cupy.testing.assert_allclose cupy.testing.assert_array_almost_equal cupy.testing.assert_array_almost_equal_nulp cupy.testing.assert_array_max_ulp cupy.testing.assert_array_equal cupy.testing.assert_array_list_equal cupy.testing.assert_array_less
The following decorators are for testing consistency between CuPy's functions and corresponding NumPy's ones.
.. autosummary:: :toctree: generated/ :nosignatures: cupy.testing.numpy_cupy_allclose cupy.testing.numpy_cupy_array_almost_equal cupy.testing.numpy_cupy_array_almost_equal_nulp cupy.testing.numpy_cupy_array_max_ulp cupy.testing.numpy_cupy_array_equal cupy.testing.numpy_cupy_array_list_equal cupy.testing.numpy_cupy_array_less
The following decorators offer the standard way for parameterized test with respect to single or the combination of dtype(s).
.. autosummary:: :toctree: generated/ :nosignatures: cupy.testing.for_dtypes cupy.testing.for_all_dtypes cupy.testing.for_float_dtypes cupy.testing.for_signed_dtypes cupy.testing.for_unsigned_dtypes cupy.testing.for_int_dtypes cupy.testing.for_complex_dtypes cupy.testing.for_dtypes_combination cupy.testing.for_all_dtypes_combination cupy.testing.for_signed_dtypes_combination cupy.testing.for_unsigned_dtypes_combination cupy.testing.for_int_dtypes_combination
The following decorators offer the standard way to parameterize tests with orders.
.. autosummary:: :toctree: generated/ :nosignatures: cupy.testing.for_orders cupy.testing.for_CF_orders
