Assert that the left and right Series are not equal.

This function is intended for use in unit tests.

Parameters:
left

The first Series to compare.

right

The second Series to compare.

check_dtypes

Require data types to match.

check_names

Require names to match.

check_exact

Require float values to match exactly. If set to False, values are considered equal when within tolerance of each other (see rtol and atol). Only affects columns with a Float data type.

rtol

Relative tolerance for inexact checking, given as a fraction of the values in right.

atol

Absolute tolerance for inexact checking.

categorical_as_str

Cast categorical columns to string before comparing. Enabling this helps compare columns that do not share the same string cache.

Examples

>>> from polars.testing import assert_series_not_equal
>>> s1 = pl.Series([1, 2, 3])
>>> s2 = pl.Series([1, 2, 3])
>>> assert_series_not_equal(s1, s2)
Traceback (most recent call last):

AssertionError: Series are equal
