What is Testing?
Testing in data engineering involves verifying that pipelines, transformations, and data outputs behave correctly. This includes unit tests for individual functions, integration tests for pipeline components, and data quality tests that validate the output data itself. A well-tested pipeline catches regressions early and builds confidence in the reliability of data delivered to consumers.
