I have been working as a test automation engineer since beginning of my career. I rarely got a chance to write test cases and do test planning. I can not say that I have done the real Software QA stuff, as I am mostly involved in automating everything that takes manual efforts. I am good with technical.

Currently, I am working on a ETL project which does not have much of QA related works. We are currently dealing with large data. But, role of a QA is very limited. It is more like an analyst.

Can give me list of things I should be knowing and learning?

ETL- Extract Transform-Load is all about validating the data and the process in which data is transferred from Source to a Target System.
Similar to other types of testing, ETL also follows the same basic principles of testing.

As an ETL tester, one should know the following:

  • Basic knowledge on database concepts
  • Data validation
  • Data Completeness
  • The transformation logic used on the extracted data.
  • Data Integrity
  • SQL Queries
  • System Performance testing
  • ETL Concepts
  • DWH knowledge

ETL testing is a broad process and requires good analytical skills resulting which ETL testers are in high demand in many QA testing companies.

Thank you Sumit. I'm asking more generic question. Not only about ETL testing. Can you share something on that?
