Execution-based testing is a process of inferring certain behavioural properties based, in part, on the results of executing the product in a known environment with selected inputs (Goodenough, 1979). What is the problem with this approach?
A. The tester has few clues to help find any faults: a set of inputs and a corresponding set of outputs.
B. The environment is uncertain - there may be faults in the hardware or software (e.g. operating system) environment.
C. In a real-time environment there is little control over the inputs. In a data processing environment the data used by tester may not be representative of that used by the end-users.
D. All of these are problems.
E. None of these are problems.
In a real-time environment there is little control over the inputs. What can be used to partially circumvent this problem? A:
A. real-time operating system
B. simulator
C. data base management system
D. virtual reality synthesiser
E. configuration control tool
Utility is:
A. the extent to which the user's needs are met when a correct product is used under conditions permitted by its specifications.
B. a measure of the frequency and criticality of product failure.
C. a function of the range of conditions under which it will operate.
D. the extent to which the product meets its constraints with regard to response time or space requirements.
