Test Data Management (TDM) is the diligent process of creating, overseeing, and curating data for software testing.

This commitment ensures that every test runs on realistic and up-to-date data, making results more trustworthy and accurate. TDM guards against software unpredictabilities in live environments and minimizing the chances of unintentional data exposures.

TDM may involve creating realistic but non-sensitive data, subsetting production data, or masking sensitive data so that it remains useful for testing but doesn’t pose security or privacy risks.
