Test data management is the process of planning, designing, storing and managing software quality-testing processes and methodologies.
It allows the software quality and testing team to have control over the data, files, rules and policies produced during the entire software-testing life cycle.
Test data management is also known as software test data management.
The primary purpose of test data management is to create, manage and maintain the source codes of an application or software for testing purposes. These source codes are different from key production source codes. Test data management enables separating test data from production data, keeping the version of tested software, bug tracking and performing other software-testing processes. One of the key objectives of test data management is to minimize and optimize the size of software testing data, as well as to gather and centralize software testing documentation and resources.
