ETL stands for Extract Transformation and Load. As the name implies, ETL testing is the process of pulling data from source database and placing it in the destination database. It is also used to convert database from one type to another. The migration of data from one database to another forms data marts and data warehouses.
ETL testing uses two important documents for its migration process. They are ETL mapping sheets and DB schema of source and target. Before the testing process initiate, these two documents should be in complete state. The ETL mapping sheet consists of detailed information about the source and destination tables. It also includes information about every column that is present in the table.
ETL testing is categorized into four types namely new data warehouse testing, migration testing, change request and report testing. In new data warehouse testing, new data warehouse is created and built from the scratch. In migration testing, the data is moved to an existing data warehouse. In change request, new data from different sources is added to the existing data warehouse. In report testing, reports are tested by validating its layout and data.
