Data Testing is about testing data. Also known as Data Driven Testing
Quite often, because "testing" has been application centric, testers for Data Systems fail to test data. They end up testing the data transport system or the database application. The data fails to be fit-for-purpose even after being "tested" because it wasn't tested.

Data Quality vs Data Testing
Unlike Data Testing, data quality doesn't seek to ensure that data has to pass a test suite in order to be usable. Data Quality seeks to probe, profile and measure data across the system/s. Data Testing is focused on application suitability.
