---------------------------------
[~liuyuchen777] is going to work on this
> Add E2E test for DropDuplicateWithinWatermark
> ---------------------------------------------
>
> Key: SPARK-48411
> URL: https://issues.apache.org/jira/browse/SPARK-48411
> Project: Spark
> Issue Type: New Feature
> Components: Connect, SS
> Affects Versions: 4.0.0
> Reporter: Wei Liu
> Priority: Major
>
> Currently we do not have a e2e test for DropDuplicateWithinWatermark, we
> should add one. We can simply use one of the test written in Scala here (with
> the testStream API) and replicate it to python:
> [https://github.com/apache/spark/commit/0e9e34c1bd9bd16ad5efca77ce2763eb950f3103]
>
> The change should happen in
> [https://github.com/apache/spark/blob/eee179135ed21dbdd8b342d053c9eda849e2de77/python/pyspark/sql/tests/streaming/test_streaming.py#L29]
>
> so we can test it in both connect and non-connect.
>
> Test with:
> ```
> python/run-tests --testnames pyspark.sql.tests.streaming.test_streaming
> python/run-tests --testnames
> pyspark.sql.tests.connect.streaming.test_parity_streaming
> ```
