WITH SOLUTIONS 2024
What is the difference between validation and verification? - ANSWER 'Validation: Are we building the
right product?'
'Verification: Are we building the product right?'
The aim of verification is to check that the software meets its stated functional and non-functional
requirements. Validation, however, is a more general process. The aim of validation is to ensure that the
software meets the customer's expectations.
What are the advantages of inspection over testing? - ANSWER -During testing, errors can mask (hide)
other errors. Because inspection is a static process, you don't have to be concerned with interactions
between errors.
-Incomplete versions of a system can be inspected without additional costs. If a program is incomplete,
then you need to develop specialized test harnesses to test the parts that are available.
-As well as searching for program defects, an inspection can also consider broader quality attributes of a
program, such as compliance with standards, portability and maintainability.
List 3 principle stages of testing for commercial software. - ANSWER -Development testing, where the
system is tested during development to discover bugs and defects.
-Release testing, where a separate testing team tests a complete version of the system before it is
released to users.
-User testing, where users or potential users of a system test the system in their own environment.
What tests should be included in object class testing? - ANSWER -Test all operations associated with the
object.
-Set and check the value of all attributes associated with the object.
-Put the object into all possible states.
What guidelines are suggested for defect testing? - ANSWER -Choose inputs that force the system to
generate all error messages.
