ETL Testing
ETL testing is a multi-level, data-centric process that validates, verifies, and qualifies data while preventing duplicate records and data loss.
What ETL Testing Does?
Asserts that an ETL process is completely extracting, transforming, and loading data.
Identifies data sources and requirements.
Validates and compares the input and output data transformed by the ETL process.
Involves the verification of data at different stages.

Well, we needed to test our application before a major release but didn't want to hire a dedicated team member. Tesvan guys filled the gap perfectly and provided the thorough testing we needed at this time. Kudos for the awesome work!
Arto Minassian
Founder, 10Web.io
Guys did a fantastic job by redesigning our application in a very short time with high quality. They are supporting you in every question during the collaboration even if it's out of the scope of their business. We just asked for videomaker contacts if any, and they made the video. That's amazing!
