Apache Spark reassigned SPARK-25779:
------------------------------------
Assignee: Apache Spark
> Remove SQL query tests for function documentation by DESCRIBE FUNCTION at
> SQLQueryTestSuite
> -------------------------------------------------------------------------------------------
>
> Key: SPARK-25779
> URL: https://issues.apache.org/jira/browse/SPARK-25779
> Project: Spark
> Issue Type: Test
> Components: SQL, Tests
> Affects Versions: 3.0.0
> Reporter: Hyukjin Kwon
> Assignee: Apache Spark
> Priority: Trivial
>
> Currently, there are some tests testing function descriptions:
> {code}
> $ grep -ir "describe function" sql/core/src/test/resources/sql-tests/inputs
> sql/core/src/test/resources/sql-tests/inputs/json-functions.sql:describe
> function to_json;
> sql/core/src/test/resources/sql-tests/inputs/json-functions.sql:describe
> function extended to_json;
> sql/core/src/test/resources/sql-tests/inputs/json-functions.sql:describe
> function from_json;
> sql/core/src/test/resources/sql-tests/inputs/json-functions.sql:describe
> function extended from_json;
> {code}
> Looks there are not quite good points about testing them since we're not
> going to test documentation itself.
> For {{DESCRIBE FCUNTION}} functionaility itself, they are already being
> tested here and there.
> See the test failures in https://github.com/apache/spark/pull/18749 (where I
> added examples to function descriptions)
> We better remove those tests so that people don't add such tests in the SQL
> tests.
