Standard: IEEE Std 829 - IEEE Standard for Software and System Test Documentation

From IEEE Software Engineering Standards Collection:

IEEE Std 829. This standard defines the content and format of eight documents that cover the entire testing process. The test plan prescribes the scope, approach, resources, and schedule of the testing activities. It identifies the items to be tested, the testing tasks to be performed, the personnel responsible for each task, and the risks associated with the plan. Test specification is covered by three document types, while test reporting is covered by four document types. The standard shows the relationships of these documents to one another as they are developed, and to the test process they document.
