ETL testing is totally different from database testing or any other conventional testing and hence the challenges faced in ETL testing also will be different. Data Warehouse always contains historical data and hence the data volume will be large. This makes ETL testing difficult in the target system. ETL Testing – Automation ETL testing is mostly done using SQL scripts and gathering the data in spreadsheets. This approach to perform ETL testing is very slow and time-consuming, error-prone, and is performed on sample data. ETL Testing – Interview Questions. ETL stands for Extract, Transform, and Load. It is an important concept in Data Warehousing systems. Extraction stands for extracting data from different data sources such as transactional systems or applications.
To conclude we can say that, the difference between manual testing and ETL testing is that manual testing covers all the areas of the application/product (UI, DB, Functionality, APi, etc), whereas ETL testing specifically focuses on the Extraction, transformation and Loading of data from the source to the target. ETL Testing is one another kind of testing that is preferred in the business case where a kind of reporting need is sought by the clients. The reporting is sought in order to analyze the demands, needs and the supply so that clients, business and the end-users are very well served and benefited.

To conclude we can say that, the difference between manual testing and ETL testing is that manual testing covers all the areas of the application/product (UI, DB, Functionality, APi, etc), whereas ETL testing specifically focuses on the Extraction, transformation and Loading of data from the source to the target.
There are several emerging data trends that will define the future of ETL A common theme is to remove the complexity by simplifying data management as a whole. ETL refers to extract, transform, load, and it is generally used for data warehousing and data integration
