cupy.testing
CuPy offers testing utilities to support unit testing. They are under namespace cupy.testing.
The assertions have same names as NumPy's ones. The difference from NumPy is that they can accept both numpy.ndarray and cupy.ndarray.
assert_allclose
assert_array_almost_equal
assert_array_almost_equal_nulp
assert_array_max_ulp
assert_array_equal
assert_array_list_equal
assert_array_less
The following decorators are for testing consistency between CuPy's functions and corresponding NumPy's ones.
numpy_cupy_allclose
numpy_cupy_array_almost_equal
numpy_cupy_array_almost_equal_nulp
numpy_cupy_array_max_ulp
numpy_cupy_array_equal
numpy_cupy_array_list_equal
numpy_cupy_array_less
numpy_cupy_raises
The following decorators offer the standard way for parameterized test with respect to single or the combination of dtype(s).
for_dtypes

for_float_dtypes
for_signed_dtypes
for_unsigned_dtypes
for_int_dtypes
for_dtypes_combination
for_all_dtypes_combination
for_signed_dtypes_combination
for_unsigned_dtypes_combination
for_int_dtypes_combination
The following decorators offer the standard way to parameterize tests with orders.
for_orders
