ETL testing is performed before data is moved into a production data warehouse system. It is also known as table balancing or production reconciliation. The main goal of ETL testing is to identify and mitigate data defects.
Using tools is imperative to conduct ETL testing considering the volume of data. Here is a list of top 5 ETL Testing Tools with Key features and download links :
