[jira] [Created] (FLINK-40980) JsonRowDataSerDeSchemaTest array tests don't cover the JsonParser deserializer

Martijn Visser created FLINK-40980:
--------------------------------------

             Summary: JsonRowDataSerDeSchemaTest array tests don't cover the JsonParser deserializer
                 Key: FLINK-40980
                 URL: https://issues.apache.org/jira/browse/FLINK-40980
             Project: Flink
          Issue Type: Bug
          Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile), Tests
            Reporter: Martijn Visser
            Assignee: Martijn Visser


{{testEmptyJsonArrayDeserialization}} and {{testJsonArrayToMultiRecords}} in {{JsonRowDataSerDeSchemaTest}} pass {{isJsonParser}} to {{createDeserializationSchema}}, but they are plain {{@Test}} methods, so the field is always false and only {{JsonRowDataDeserializationSchema}} is tested. The top-level array handling in {{JsonParserRowDataDeserializationSchema}} from FLINK-18590 isn't covered by any test in {{flink-json}}. We should run both tests as {{@TestTemplate}}, like the other tests in the class that use the parameter.
