Скачать или смотреть Data Transformational Testing and Data Comparison

Understand how to implement white-box testing for data transformations using the Datagaps DataOps Suite. This video explains how QA testers can independently replicate transformation logic—without copying developer code—to validate data accuracy.

What You'll Learn:
Use raw source files and reapply transformation logic from scratch
Validate transformed results against expected output
Pinpoint mismatches down to specific fields (e.g., Geography Key)
Detect mapping or logic errors between environments

This is essential for maintaining trust in complex transformations and business rule implementations. Watch as we demonstrate isolating issues like logic errors in the Geography Key transformation.
