> The recent coercion test refactoring (SPARK-55114, SPARK-55135, SPARK-55164,
> SPARK-55235) introduced a pandas-based golden file testing pattern. These
> four test files in {{pyspark.sql.tests.coercion}} share significant
> duplicated code:
> - Timezone setup/teardown for deterministic results
> - Golden file read/write with {{SPARK_GENERATE_GOLDEN_FILES}} env var
> - Type/value string serialization helpers
> Proposing to extract a {{GoldenFileTestMixin}} in {{pyspark.testing}} to
> reduce duplication and make it easier to add new golden file based tests in
> the future.
