> Add unit tests for ReadLimitRegistry
> ------------------------------------
>
> Key: SPARK-60285
> URL: https://issues.apache.org/jira/browse/SPARK-60285
> Project: Spark
> Issue Type: Improvement
> Components: PySpark, Tests
> Affects Versions: 5.0.0
> Reporter: Anna Liang
> Priority: Minor
> Labels: pull-request-available
>
> Add unit tests for ReadLimitRegistry in pyspark.sql.datasource_internal.
> The existing Python tests (test_python_streaming_datasource) never rebuild
> ReadMinRows, ReadMaxFiles or ReadMaxBytes through the registry, and the
> missing/unregistered type error paths are not covered. Coverage reports show
> ReadLimitRegistry as uncovered.
> The new tests rebuild all five builtin ReadLimit types from their dict form
> and verify the PySparkException raised for a missing or unregistered type.
> Running test_python_streaming_datasource raises coverage of
> datasource_internal.py from 39% to 57%.
