ASF GitHub Bot updated SPARK-57363:
-----------------------------------
Labels: pull-request-available (was: )
> Add tests for Index.identical in pandas-on-Spark
> ------------------------------------------------
>
> Key: SPARK-57363
> URL: https://issues.apache.org/jira/browse/SPARK-57363
> Project: Spark
> Issue Type: Test
> Components: Pandas API on Spark
> Affects Versions: 5.0.0
> Reporter: tonghuaroot
> Priority: Minor
> Labels: pull-request-available
>
> Index.identical in pandas-on-Spark (pyspark.pandas.indexes.base.Index) has no
> positive test coverage. The method behaves like Index.equals but additionally
> requires the index name(s) to match, yet the test suite never asserts its
> True/False result - the only reference to it is a comment in test_equals
> noting that equals ignores the index name unlike identical. This adds
> positive parity tests in IndexBasicMixin
> (python/pyspark/pandas/tests/indexes/test_basic.py), comparing
> Index.identical against pandas for: a single Index compared with itself;
> equal elements with the same name (-> True); equal elements with a different
> name (-> False, the case that distinguishes identical from equals); unequal
> elements (-> False); a MultiIndex compared with itself and with another
> MultiIndex that has the same tuples but different level names (-> False); and
> an Index compared against a MultiIndex (-> False). Cross-object comparisons
> are wrapped in option_context('compute.ops_on_diff_frames', True), mirroring
> the existing test_equals. No product code changes; tests only.
