ETL TESTING What is ETL Testing: Much ETL testing today is done by SQL scripting or eyeballing of data on spreadsheets. These approaches to ETL testing are very time consuming, error-prone, and seldom provide complete test coverage.

ETL TESTING ETL stands for Extract-Transform-Load and it is a process of how data is loaded from the source system to the data warehouse.  Data is extracted from an OLTP database, transformed to match the data warehouse schema and loaded into the data warehouse database.  Many data warehouses also incorporate data from non-OLTP systems such as text files, legacy systems and spreadsheets.
