Techniques Validation |
Formal : use math and logic to investigate design, documentation, functionality and behaviour of software Fault injection : purposely input wrong values to test how system behaves under fault conditions |
|
|
Techniques Verification |
Consistency test: To ensure correct system syntax, parameter correct parameter matching between each procedure and correct typing is used throughout system. Measurement technique : measures error possibilities, understandability and structure of system. |
