## Background: - Currently, the mock has the limitation, that it only can run UDF with static output parameters ## Acceptance Criteria - The user has a way to define the default_output_columns() function - If the user doesn't define output columns, call default_output_columns() before running the run method - Check if the output of default_output_columns() is valid - Provide a way that the user can validate the output default_output_columns() regarding its own criteria - Validate the output of the run method against the output of default_output_columns()
