Value boundary analysis is a functional software testing technique that tests the behavior of a software system or component when it receives inputs that are at the boundary or edge of the expected range of values. Value boundary analysis is based on the assumption that errors are more likely to occur at the boundary values than at the normal values. Test inputs are obtained from the derived threshold of the given functional specifications, such as the minimum, maximum, or just above or below the boundary values.Value boundary analysis can help identify errors or defects in the software system or component that may cause unexpected or incorrect outputs, crashes, or failures34Reference:CISSP All-in-One Exam Guide, Eighth Edition, Chapter 8: Software Development Security, p. 497;Official (ISC)2 CISSP CBK Reference, Fifth Edition, Domain 8: Software Development Security, p. 1015.
