Hi,
ETL testing is where you verify if your source data is correctly extracted, transformed and finally loaded into the target database or not. You need to verify at each level if your source data is matching with the target.
Process for ETL testing is you first identify your source tables or raw tables where data is present. Then check for the transformation logic if correctly implemented to load the data into target. Now verify your target DB which will have the transformed data of the source. you need to verify the correctness of data in the target DB like null values are not loaded, any data types is mis-matched, values are correct, garbage value is not stored, etc.
ETL tester needs the knowledge on the ETL development otherwise he will not be able to understand the requirement completely.
Please let me know if you need any more information.
Thanks and Best regards,
