5 Best ETL Automation Testing Tools in 2021

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 :

❓ What is ETL Testing?

ETL testing is a software testing process which is done to ensure that the data that has been loaded from a source to the destination after business transformation is accurate. It also involves the verification of data at various middle stages that are being used between source and destination. ETL stands for Extract-Transform-Load.

💥 Why is ETL Testing required?

While data transportation from extraction to loading, there are some chances of occurring some human or system errors that can result in poor information transferred through the whole system. ETL testing helps to ensure such errors do not occur and eliminates such defects which can harm the whole system.

✅ How to do ETL Testing?

Below is a process on how to do ETL testing:

  • Step 1) Identifying data sources and requirements
  • Step 2) Data acquisition
  • Step 3) Implement business logics and dimensional Modelling
  • Step 4) Build and populate data
  • Step 5) Build Reports
