56. What are ETL tester responsibilities?

This question is specific to those looking to take on the role of ETL tester. It will require the same knowledge as those who run the ETL system, but may also require knowledge about double-checking the system and how to go about that process.

An ETL tester is responsible for writing SQL queries for various scenarios. They run a number of tests including primary key, duplicate, default, and attribute tests of the process. In addition, they are in charge of running record count checks as well as reconciling records with source data. They also confirm the quality of the data and the loading process overall.
