示例1: _test_base

# 需要导入模块: from numpy import testing [as 别名]
# 或者: from numpy.testing import assert_warns [as 别名]
def _test_base(self, argsort, cls):
        arr_0d = np.array(1).view(cls)
        argsort(arr_0d)

        arr_1d = np.array([1, 2, 3]).view(cls)
        argsort(arr_1d)

        # argsort has a bad default for >1d arrays
        arr_2d = np.array([[1, 2], [3, 4]]).view(cls)
        result = assert_warns(
            np.ma.core.MaskedArrayFutureWarning, argsort, arr_2d)
        assert_equal(result, argsort(arr_2d, axis=None))

        # should be no warnings for explicitly specifying it
