In its embodiment, ETL testing expects to respond to the inquiry:
How can one guarantee that the software does what it should do and doesn't do what it shouldn't do?
The essential objective behind ETL testing is to get sufficient certainty that the software under ETL testing produces the right result for a given input.
Something critical to remember while finding out about ETL testing is that ETL testing doesn't further develop programming quality by itself.
