Description
Currently dynamic UDF resolution is only testable through integration tests as it relies on communicating with an Artifact Management Repository, typically an external service. At this point, integration tests are not open source either. This issue is to track creating a unit test that tests this functionality by creating a local artifact management repository and leveraging it in unit tests.

Research direction
Start with coral-hive/src/main/java/com/linkedin/coral/hive/hive2rel/functions/HiveGenericUDFReturnTypeInference.java and trace how dynamic UDF resolution communicates with the Artifact Management Repository. Create a local artifact management repository for the unit-test setup, then verify the dynamic resolution path without relying on the external service.
